Need source for canopy for Curare
 

HI,

I am building a Curare from the Eureka short kit and need a source for a canopy . Does anyone know ehere I might be able to buy something that will fit?

If all else fails aI could carve a block - but I would prefer the look (and weight) of a canopy.

Thanks!!

RE: Need source for canopy for Curare
 

Kemblin, I've ordered the same kit but it has yet to arrive. Should be here in next couple days. Might try Blue Jay for canopy from one of their Chaos'or one of their other Bridi reporductions. I don't know but I would think the canopies should be close to the Curare. Keep us posted how you are progressing with construction. Did you get the plans? Are you going to put retracts or go for non retracts? What engine are you using. I'm going with a new 61 OS FX. Don't think I will pipe it.

>>Did you get the plans? Are you going to put retracts or go for non retracts? What engine are you using. I'm going with a new 61 OS FX. Don't think I will pipe it.

I got the plans as a PDF file with the short kit - but also had a series of .pdf's that a kind soull from this forum sent me. These have been very useful for identifying the parts in the short kit (they are not labelled and it is quite fun working out all the parts!) and for cutting out some of the pieces that you supply yourself.

I am using Kraft electric retracts as I used these years ago and have 2 or 3 sets that I managed to acquire via ebay.

I am making this one electric (I have another with a Webra 61 rear exhaust). I am using a Scorpion 4025 motor with a 6S 500MaH battery (same as my Trex 600) - It will be propped to pull about 1600 Watts - or a little over 2 horsepower.

Right now I have sheetd the wings and tail - using 1/16 balsa and Gorilla glue - my first attempt - but it worked great. I have much of the fuselage done - but have not fitted and carved the noise blocks yet. There is quite a lot of carving and sanding to do!

I could post pix if you are interested? I have also been following an excellent build thread on anopther site where a guy is building an electric Curare for SPA competition. (you can Google it easily). I am attracted by competition but cant see not having retracts - or a tuned pipe on the Webra - so I guess it will be BPA for me!

RE: Need source for canopy for Curare
 

I ordered all the plans Eureka had but not sure what I will get until it all arrives. This will be my first attempt at scratch building, which is about what Eureka sells. He just cuts out the main pieces and up to you to try to read plans and glue together and dig up everything else like canopey or at least that is what I understand. Have build numerous regular kit planes, never a scratch. I'm not much on electric; to stupid to understand all the jargon with electricity so will stay with nitro. Besides like the sound and smell of burning nitro. Im either going with Robarts or Spring airs. I have a set of spring air for new Chaos to replace old leaky Rhom. If I like them I'll go another set for Curare. Sounds like you went with the foam wing route. Im going the built up. He's drilling ribs for wing jig. Tried foam a couple of times but have to have my son haul over all his slate and extra weight to sheet. Just more trouble then it is worth for stupid me. Can't teach old dogs new tricks.

RE: Need source for canopy for Curare
 

Yes, I went with the foam wings. It was my first time - but it went about as easily as I could have hoped! I bought wing skins (10 inches wide) from Balsa USA - so no edge-joining to do - then applied Gorilla Glue with a fine foam roller. I laid them all lined up in the foam shucks and sat a really heavy hi-fi speaker (I could barely lift it!) on top for 24 hours and they came out perfectly!

I used to build and fly Curares in the late 70's - they came as a fiberglass fusalage and obechi sheetd foam wings and tail then - much easier. I kept one form those days - but am almost to afraid to fly it in fear of losing it after all this time.

I am getting hooked on electric - so easy and convenient - but I like the sound of my Webra as it comes on the pipe.

You are right - the Eureka kits are closer to building ffrom scratch than a more typical 'click it together' modern kit - but at least you dont have to fret out all those plywood parts! Not to mention the 20 odd parts that make up the tail!

If you need any of the "component" .pdf files (they show each part full size with its ID) let me know. It is quite confusing in that the part kit provides multiple thinner parts that you sandwich together instead of the thicker wood on the plan - so you spend a lot of time saying "oh - here is F7 - or whatever - only to find 3 more!!)

Ah well... back to carving and sanding!

RE: Need source for canopy for Curare
 

Guys,

I will be making a canopy for the Curare using an original from an MK Kit. I'm not sure of the time frame, but you can watch for it at www.klasskotemo.com You will most likely see a laser cut short kit for the Curare from Laser Technologies in the future also.

RE: Need source for canopy for Curare
 

I'm definately in the market for one as I'll bet Kemblin is also. Just post when you have them ready for shipment and I'll send either check or credit card or what ever else you want.

Kemblin: I'll be in touch for part file when the kit arrives. I ordered it last week but Eureka was waiting on an order of Balsa. Got a note the other day it arrived so he will probably be shipping soon. I may not start for a while as I need to fly a couple of others for a while before spending time in the shop on a new bird. I also have a p-40 I need to start also. I to think the enjoyment and pride of the sport is building. I like to stick out my chest with my origional colored model and proudly announce, "I built it!"

RE: Need source for canopy for Curare
 

Kemblin: Postman just left the Curare. Just glanced at plans and cut wood. My first objection is the plans are in German and meters and I don't speak German nor do I measure in meters. However, perhaps I can figure it all out. I am impressed with the plans detail and how complete they appear to be. Just glance at the parts they are cut cleaner then most other kits I have built. With Blue Jay the parts are cut out completely rather then left in the sheets like sig or GP., but then there are not that many parts in a chaos. However, I think the component pdf file would be very helpful. If you don't mind send it to [email protected]. THANKS

RE: Need source for canopy for Curare
 

I sent the individual pdf's by email. I think they help a lot. If you look closely on the plan (at least the one I got from Eureka) it has (some) english equivalents for wood sizes.

RE: Need source for canopy for Curare
 

Kevin,
You might give Sid Austin a call and ask him about a canopy. Sid builds up the Eureka kits and sells them as ARC. His ARC kits have a plastic canopy included (I know this because I'm building one).
Although he is not specifically selling the canopies, you might be able to work something out with him.

RE: Need source for canopy for Curare
 

Kevin; did not get an email PDF file on componats to identify. I'm not a computer guru so may have missed something. How about an email with an attached PDF with the componants? Thanks guy!

RE: Need source for canopy for Curare
 

I have a copy of the PDF's.....I should , I drew them. Check your mail.

Regards,

Pedro Luzuriaga

RE: Need source for canopy for Curare
 

Thanks Pedro,

I hit his email size limit (6 megs) - I think he will like them they are just so darn useful!!!

Thanks for drawing them and for re-sending them!

Kevin

RE: Need source for canopy for Curare
 

Thanks Kevin and Pedro for the copy of the compoants they will help when I start making big parts out of the little ones. By the way Kevin, called Sid Austin at Old School Airplanes and bought his last canopy for the Curare at $8.95 plus postage. He will be getting some more in a couple weeks. He said this one is shadded rather then clear, but no problem for me. I wont have a pilot in the bird anyway. If I owe anybody anything for the copy of compoants, let me know and an address. Stay in touch and keep posted on outcome of bird.

RE: Need source for canopy for Curare
 

Don at Eureka sells a canopy, but they may be an extra or he hasn't got them in stock. You can get the same canopy from Wing mfg.
It is listed as a pattern canopy. They sold a kit of the Curare years ago, and still have the canopy available. Price was $10.00.

Anyone have any idea about retracts? Someone mentioned B&D but I don't know where to find them or if they are still in business.

matadco,

I saw Sonny Brown the Owner of B&D at The Toldeo Show yesterday. They are very much in business. Your best bet to get in touch with him is to call him. He is in and out of the shop and does not have voice mail. You have to keep trying until you get him.

RE: Need source for canopy for Curare
 

Hey Guys,

As far as the part indentifying, the PDF on Curare page shows the parts included, and the part numbers. That should be enough to figure out what is what. Since this seems to be confusing, which I understand, I will start including a layout of each sheet in my kits with part numbers listed. I will also list the parts that need to be laminated, along with any minor changes I made in the kits, which should be few. Usually changes only include converting to standard motor mounts to accept a wider variety of engines, or as on the Curare, changing the tri stock sizes to sized that are actually available, like the top turtle deck tristock that was about 1" x 1/2" on the plans. I don't know anywhere you can find tristock that isn't 'square'. Definitely check with Sid for the canopy, and I check with Wing when they get back from Toledo to see which canopy number is for the Curare.

I strongly believe that the kit's design should be left as is, not modernized to tab and slot building. It just doesn't seem right to do that. I respect the older designs too much.

As for the EAC kits are like scratch building, you are right. I am a kit cutter, and that has always been the job of kit cutters, to bridge the gap between full kits and scratch building. I try to cut all of the parts that need to be cut to shape, such as fuse sides, formers, doublers, wings ribs, etc. The sheet stock and sticks aren't hard to get. Cutting the parts to shape is a problem to a lot of builders, either lacking the equipment, time, or incentive to cut the parts them selves. That is where kit cutters have always come in, although we are few and far between now adays.. I will also include wing jig holes in the ribs if you let me know when the short kit is ordered.

Any suggestions on parts I missed on kits would be appreciated. I will try to add it on future kits. It is easy to miss something when starting at the plans that much, a second set of eyes is always helpful.

To bring everybody up to date on the foam wings I sell. They started life with Ralph Andre at wing Mfg. That is why the list goes back so far. Brian & I purchased the wing division of Wing Mfg from Ralph in the early 90's, including patterns, inventory, and the cool machines Ralph designed for cutting wings, back when I was a partner in Dynamic. Last October, I aquired the wings from Brian, to expand EAC, and give Brian more time to concentrate on the cockpit kits he makes, which he has turned into an art form, in my opinion.

Eureka Aircraft is starting it's 4th year, and I want to thank all of the builders who have made it possible for me to bring back to classind birds, and bring back building into the RC hobby. Long live building. Wouldn't it be great to never see an ARF again????

Thanks for listening....

RE: Need source for canopy for Curare
 

Guys,

I completed the Curare Canopy Plug today. It is made using a canopy from an original MK Curare Kit. This is an exact reproduction, not a "close" copy. The plug needs to cure for a few days. It will them be primed, sanded and polished. It will be ready for vacuum forming in a week to ten days. PM if you are interested in one. Please see the attached pictures.

RE: Need source for canopy for Curare
 

Don,

I hope I did not cause any offence regarding my comments about identifying parts etc.!! Certainly not my intention.

Any weakness (in identifying parts etc.) would be my own stupidity.

I am more than happy with the short kit and every part of the service that I received from you. I have been recommending you to my club mates.

I am very much enjoying building my Curare - in fact I am thinking of coming back for a second one!! It IS a big change from the ARF world that we have all become used to - but that is a GOOD change from my own perspective - I am enjoying a side to the hobby that I had almost forgotton.

The foam parts have also come together better than I ever expected - as this was the first time that I ever sheeted foam wings. Ed Lyerly (whose build thread I am following closely) pointed me at an SPA article that told me how to use Gorila glue and it all worked great.

Like Ed I am building an electric version - which requires a few minor changes - but it is SUCH FUN to be building again.


So ... in summary I am VERY HAPPY with my short kit and my project!!

Kevin

RE: Need source for canopy for Curare
 

Don, I to want to express my complete satisfaction with the Curare you just sent me a couple days age. I can recommend your work to anyone. I have not started the kit, but as we talked on the telephone I look forward to the challenge. This will be my first experience at what amounts to scratch building. I have the parts numbered from the PDF Pedro emailed, so ready to go just as soon as I get time. Thanks, Tom Matthews

RE: Need source for canopy for Curare
 

Canopy looks good, Leo. Good luck on it.

Kevin, no offense taken. Any input is helpful to me, since a lot of customers don't relate any issues back to me, so the kits can improve. Those that have given feedback have helped immensely.

I am glad to help bring building back to RC... There are so many forgotten gems out there, that I have tended to stay with vintage stuff, and will be doing some short kits of magazine plans of some cool rarely done kits.

In a couple days, I will have the Atlas short kit ready, and the scaled Tiporares from Doxilla's thread.

Keep on building.. A day at the field with NO ARFS is a great day indeed!

RE: Need source for canopy for Curare
 

Kevin/Don: Looking over the plans they call for 3 servos mounted in wings, one for alerons, one for flaps and the third for main retracts. Looking over fuse I fail to see a separate servo for the nose retract. I can't imagine how to connect a wing mounted servo to retract the nose gear in the fuse nor can I imagine how to mount a retract servo in the fuse to retract wing mounted gears. Only way I know is to use pneumatic retracts, but I am open to learning how to use manuel retracts on detachable wings mains. I have always been dedicated to OS engines but am thinking about either a Rossi or Webra in the Curare. What is your opinion and pros and cons of each? I am a neophyte when it comes to patterns.

O.K Well first let me admit that I am spoiled here as I have mostly used electric retracts that only require a wire like a servo to connect them. I really like the old Kraft units they are so tough - they laugh at grass fields!! I have seen mechanical setups using either a servo in the fusulage under the wing. that operates the nose retract - I have also seen single servo solutions with the retract servo mounted in th wing. They all looked much more complicated to me than either the electric (easiest) or the pneumatic (next easiest IMHO).


>>I have always been dedicated to OS engines but am thinking about either a Rossi or Webra in the Curare. What is your opinion and pros and cons of each? I am a neophyte when it comes to patterns.

Probably Fords and Chevys!! I use Webra 61's - like the original. Fairly powerful with the Dynamix carb, tuned pipe and a Perry pump. I like them and they are freely available. I have also heard "powerful" and "Rossi" in the same sentence many times, but have no personal experience. These days I would be very tempted by the Jett range.

Talking of servo's - I decided to follow Ed Lyerley's lead and mount a servo in each tailplane half and one in each wing. The rudder I have kept as a "pull-pull" mounted under the wing.

I am nearly at the stage of having to decide if this is going to be a 3/4 oz glassed and epoxied ship - or monokoted. I am abit worried about the weight of a glass and epoxy finish for my electric bird.

RE: Need source for canopy for Curare
 

Thanks Kevin, actually I was giving consideration to Spring Air retracts.They are air up, spring down which offers a certain amount of security in the event of air failure. However, I personally favor the manuel retracts but never thought about it on a trike gear and I don't want to build this one tail dragger. I have no experience on electricts. Really my understanding of electricity is simular to my understanding of Greek. However, how much do they draw from a standard 7.2 v/110 amp nicad? Any chance of loosing radio power operating retracts? Just asking. Right now I am concerned about Spring Air. Ordered a set to replace Rhoms in my Chaos two weeks age and they haven't arrived yet. Surly the pony express can ford the Mississippi in two weeks. Any way thinks for input. Will advise of my decissions.

RE: Need source for canopy for Curare
 

The Kraft retracts (and I think that there are modern equivalents) just use Servo motors inside (1 in each retract) so they draw similar power. They plug in just like a servo too (an amplifier about the size of a micro servo plugs into your retract channel and 3 wires from it pluig into the retracts. I have never had one hang up in all the years (too many!) that I have used them.

I hear good things about the Spring Airs. ONly thing is I constantly hear "I cant use retracts I fly off grass" which leaves me to believe that some retracts are not that strong. I have always flown off grass with the Krafts and never had any issues.

My Curare is coming along. I was delighted to find that the 6S 500 battery from my Trex 600 fits in just fine under the canopy. I just have to make the decision - to glass or to monokote. I am leaning towards the latter for weight - but still have a hankering after that gleaming epoxy finish! Silly really - once they are 5 feet away you cant tell!

I am quite tempted by the Atlas that DOn mentions - it would be an ideal home for one of my Webra 61 Rear exhaust motors. Cant have too many pattern planes!

I would like to enter a BPA contest - but to do so it either means an long trip (I live in Maryland) or tryng to get a group together and create an event up here. Anyone reading this interested?

Anyway ... let us know how your build goes!

RE: Need source for canopy for Curare
 

I'm still waiting on Spring Airs for my Chaos. Had some old Rhoms but they leak and I have no idea how to repair so ordered two weeks ago new Spring Airs. Got an email they were retooling but would finally ship this week so should get installed and test the Utter Chaos. Where can I find about electric (Kraft) retracts. Sounds like I may consider them in the Curare instead of pneumatic. Really like mechanicals better, but not sure I want to go into the two servos deal. Still thinking about an engine for Curare. I have a 61 OS in another bird I'm not flying so make take it out for Curare. Save a couple hundred. Got to get another receiver. Have an extra 72 meg but probably go with 2.4 gig. Just a lot of stuff to buy for the Curare or take it out of other birds, which I don't like to do. May want to fly one of them and then go through to R&R. Give us pictures of how things are coming.

RE: Need source for canopy for Curare
 

I have been flying two servo mechanicals (Hobbico's) off grass in my Curare for about 5 years now, other than a drop of oil on the pivots and sliding bits there has been no other issues. I use two 1/8" (3mm) nylon bolts on each leg, and never had a dingle to prove whether the bolts would actually break as intended... With modern batteries (1100mAh) there has never been any power/capacity issues either, even up to 10 flights per day. KISS works every time with retracts, just look at the thing every now and then and make sure the legs haven't bent and sticking in the wells and there really isn't much to go wrong with them.

RE: Need source for canopy for Curare
 

I don't know about not flying off grass fields with retracts. I have three birds with retraccts, two mechanical and one with pneumatic Robarts. No problems but then again maybe our grass field is in pretty good condition. We have over 100 members in our club and several have retracts all on all sizes of birds with no problem. But then again maybe we keep the field in good condition by mowing weekly and occasionally, depending on rain, more often.

Kevin, where would I look for electric retracts? Can't google Kraft other then Phil who is now by by.

RE: Need source for canopy for Curare
 

Yeah - everything Kraft is now bye-bye. I found mine by watching ebay etc. Although old they really work well and are great value when you can pick them up. All you have to do is change the Kraft plug for Futaba or JR. Years ago (late 70's) I flew pattern competitively (in England) and used the then state of the art Kraft Signature series radio (still have it - and still prefer its control sticks even to my 12X!!) - so I had some stuff left over from then (including the Curare I flew in the British Nationals!) - and some I got via ebay - brand new amazingly enough. If you are the patient type and can watch ebay (or other for sale lists like this site) - they are great retracts and SO easy to install.

I typed "electric retracts" into Google and found a couple of current vendors. You might want to check them out.

I'll post some photos of mine so you can see.

Kevin

RE: Need source for canopy for Curare
 

I think the idea that retracts can’t be used on grass is a myth sort of like the myth about nose gears being difficult to use. Have no clue how this stuff gets started.

RE: Need source for canopy for Curare
 

What, you mean people fly of stuff that ISN'T grass? What sort of stuff is it, and where do you get it from?:D
Evan, WB #12.

RE: Need source for canopy for Curare
 

I am about ready to start building this Curare BUT, I can't read the plans to determine what additional wood and its size I will need. What do I do? I am measuring the triangle top and bottom side and then the thickness of the top and bottom fuse planks. Is that right and if not what is right. I can't find any numbers other then 25 X 18 triangler stock. It measures out on the plans 1/2 inch triangle but to lighten up I could use smaller say 3/8 in triangle. Same with the top planking measures 1/4 in. thick but how about 1/8 in. thick? This will be the first bird I have built from plans only and then not have them in English, which is the only language I understand.

RE: Need source for canopy for Curare
 

You can measure the plan sizes in mm and convert to inch stock quite easily, it won't make any difference to the build. Use only the lightest stuff you can find for the fuselage, and it you decide to use thinner wood than specified, remember that you might not be able to achieve the same cross sectional shape, you might run out of wood to sand. There is a lot of wood in the Curare fuselage, and most of it ends up in the scrap bin.
Evan, WB #12.

RE: Need source for canopy for Curare
 

Matadco,

I used 1 inch triangle for the top of the fuse and 3/8 triangle for the bottom. I used 1/2 inch for the top and 3/8 for the bottom. DO NOT go any smaller - or your fuse will look like a box instead of the beautiful rounded shape that you end up with after carving most of the above away! Also your ply fuselage members will be cut for this size of triangle and wont fit right if you skimp on the wood. Even with the size I used I was worried about shaving it too thin to achieve the nice rounded section needed.

Also... these things move pretty fast and are subject to quite a load as you do aerobatics - I dont think too light is the way to build. Also if you use soft balsa it really does not add much (or save much by skimping). I think you save more by careful use of epoxy (not too much) and using cyano when possible.

I ordered 2 sheets of 1/2 inch * 3, two of 3/8 * 3, 2 of 1/8 * 3, aileron stock, strip balsa for the trailing edges (remember I had foam wings), a couple of blocks (3 * 1 inches) for the nose etc., 2 sizes of dowel (for the wings and the removeable canpy, nose block etc. - [you may not want a removable nose block - but it is great for getting at an electric motor). I also ordered some 1/16 and 1/32 ply for re-inforcing the removable parts etc. , a little 1/8 ply for servo trays etc.and finally some hardwood "engine bearer" wood for mounting the retracts in the wings. That was about it I think. (I did not mention the wood for skinning my wings and tail as you dont have foam - but if it is not in your kit add that - I think 3/32 is normal for skinning built up wings and 1/16 over foam).

After that it was just hinges, servo extensions, the wire for the pull-pull ridder link, control surface horns, fiber glass for joining the wings and glassing the fuselage (have not decided about the wings yet - might use monokote).

Its hard to think of everything - and having just lost my local hobby store I am now reduced to ordering on line. I hope I am not violating any rules here by saying that I am delighted with the quality of both wood and service from Balsa USA.

Let us know how your build is progressing. I hope to post some photos of mine soon.

RE: Need source for canopy for Curare
 

Thanks Kevin, you have been a world of help in this project. Trying to figure this out is considerable different then kit building. I have a short ruler with one side metric and the other side standard. The fuse top triangle stock calls for a 25 X 18 which according to this ruler is about 1" X 3/4". The bottom triangle is 10 X 10 which equals about a 3/8" X 3/8. I have also ordered another set of plans which I hope will be in English and std. measurements. I ran down some old articles and printed them off. The articles call for spoilers along with flaps and 3 servos in the wing, 1 for retracts, 1for alerons and one for the flaps. That would put 4 more in the fuse, one rudder, elevators one nose retract and engine. Is that what you have? The other side of the coin I could use pneumatic retracts but where do you put the tank and action valve? The Rhoms I had in the Chaos turned out to be ok. The problem was a line popped off at the wing cross over and the end went below the skin. I finally noted an open T but being forgetful, I exchanged it for a coupler and then one side main did not work but the air leak stopped. I finally reconnected all lines and everything works like it is suppose. I now have an extra set of new Spring Airs which I had intended to put in the Curare, but may change my mind and go with manuels and two retract servos. What do you think? About to decide to go with the OS power. That is what my hobby shop owner recommends who is ex competative pattern flyer and sponsored my two kids when they were competative pattern flyers but then again that is what he sells. I'm trying to get the list of woods together. Picked up a couple of pieces yesterday but will order the rest from Balsa USA. Porbably take a week to get here. Will keep you advised on progress. I thought I was a pretty good builder but this project is definately keeping me humble.

RE: Need source for canopy for Curare
 

Since Servos are so cheap now (relatively!) I plan to put the aileron and flap servos in the wing in line with each control in the modern manner - so 4 (small, digital - Futaba 9650) servos in the wing - but not in the center as they did it in the 80's. I am going with the combined flap and spoiler arrangement like the earliest Curare - rather than the seperate flap and spoiler - really just to save effort and weight.

For the elevators I plan to do the same thing - putting a servo in each tailplane half (futaba 9650 again), mounted on plywood "covers" underneath each half. I use 2.4Ghz radio - so no worries about long servo leads.

So that leaves me with motor and rudder in the fuselage under the wing (remember I use electric retracts - just plugged in like servos). For the rudder I plan to use a "pull-pull" arrangement with fishing line. I am using a Futaba 9252 for that.

I think that there is plenty of room in the fus. in the space over the wing (or if , like me you mount the fuel tank there for balance you could put the tank up front where the fuel tank "should" be) for an air tank for pneumatics. The actuating valve could be mounted on the servo tray next to a retract servo (you would not need a particularly special servio just to actuate the valve). My other Curare (the one with the Webra 61 in it) has the tank mounted over the center of gravity (I used a Perry pump) so that the CG does not change as the tank empties. It works fine - but does consume space over the wing. Not such a problem with the new modern radio as it is much smaller.

I hear good things about OS engines I am sure that you will be happy with it - especially if you dont plan to use a tuned pipe al la SPA.

RE: Need source for canopy for Curare
 

Kevin: Being unemployeed and unemployable I don't think I will go the digital servos route but rather stick to "el cheepos". However the idea of individual servos in the rear on elevators sounds like a plan. I to think moving the servos out in the wings for alerons is also a plan, which is what I do on all birds now. Fuel tank will be mounted according to planes, in the nose behind the firewall. I too am unsing a 2.4 gig and with that received takes up very little space and very little weight. So the small retract air tank can be mounted in fuse aft of wings.Using Spring Air with a small control valve and one air line would not take up the space the Robarts would. I also use a Hobbico mini servo to operate the control valve the same as I do on Rhoms in Chaos. It only requires a 1/4 travel and little resistance so the mimi servos are great space and weight savers. This leaves the battery pack forward of the wing saddle behind the tank which should off set the weight of the servos in the tail and keep balance. There is plenty of length in fuse but width is only about 2" , just wide enough for side by side cervos for rudder and engine over wings. This sounds like the plan but you know the best laid plans of mice and men are spoiled by things that might have been. I'll let you know. Again thinks for all your help.
