RE: GP Cap 232
 

Bubbagates, Lou55..... thank you both for the info! The Cap fits and it's going to be ordered tonight. Again thanks!

RE: GP Cap 232
 

:)ricomari...

Glad it fits in your present vehicle. Shame to see you purchase a new truck just to haul the CAP.

Thanks
Barry

RE: GP Cap 232
 

New truck would be cheap compared to the price I'd pay to my bride! :)) Naw, she's very understanding, only a few dirty looks when I ordered the Cap, engine and things needed to complete............oh, oh, just got the honey do list, got to go, can't play now ........Later :))

RE: GP Cap 232
 

hey bubba, just wanted to say HEY, and was wondering how ur cap is going,?? u been flying lately.? Every night during the week after work a keep cleaning it hehe its spotless but i cant help it hehe
I just purchased another plane, i couldnt help myself and a DA 50 im putting it in a Aero works Extra 260 that should be arriving just after xmas i think..
hope the build and quality is as good as the cap, well i wont be flying the cap this w.e comming because the Wife has something planned :( cant help bad luck, hehe
wait till i tell her i just spent another 1000 bucks HAHA i dont know how im going to to explain that HEHE

RE: GP Cap 232
 

Hello ricomari,

The GP CAP 232 will be a great entry level plane to Giant Scale Gas models. For that reason any GP Performance Series model would do very well. The YAK 54 is great for all around sport flying, though a little on the fat side for serious 3D. The Yak has a much smaller cowl which is a tad tight fitting for anything bigger than a 40cc gasser. The CAP and the Yak (as well as the GP Super Chipmunk, and the Wagstaff Extra) need all the weight you can have in the nose to balance right on CG without adding extra weight. A Fuji will, provide the most weight possible. Specially the magneto ignition model. That would be detrimental on the power to weight and wing loading of the aircraft, but it will be fine for sport flying.

As far as value for the money, the new 25% Wild Hare Yak is also an excellent choice, and it can be powered with a smaller gas engine. This makes the plane a great sport flyer with anything from an OS 1.60 or Saito 1.80 on glow or a Brison 2.4 or similar gas engine. And with a DA-50 it is as hot it can get. Other possibilities are Moki/Mark 1.80 or 2.10, Saito 270/300 twin, Saito or OS radial engines, 3W28, Roto 35, Evolution 36, ZDZ-40 or 50, almost anything in that weight range will give excellent performance.

If you have the cash the QQ 73" Yak will fly beautifully with an Evolution 26 GT2. [link=http://www.somenzini.com/downloads/videos/evo73_hi.wmv]Check the video out.[/link]

I am about to finish my CAP and I am very satisfied with the finish and engineering quality that has gone into this plane production. Some of the points on the plus side :) are; (1) the quality of the Monokote finish is outstanding. (2) The cowl is big enough to almost completely conceal a 50cc size engine (3) the overall weight is less than 16 Lb, for a 27% plane with 1168 Sq. In. of wing area that's a very good loading. (4) The landing gear struts are built from a composite material which makes them fairly flexible and at the same time stiff enough to contend with the harshest landings, and they have a very scale sweptback with a thin airfoiled profile. The fiberglass wheel pants are finished with their respective reinforcements and 4-40 mounting blind nuts. (5) The canopy don't need to be glue in position, it fasten with four sheet metal screws. (6) All flying surfaces are hinged with Robart style hinges, and the pre-drilled holes are a perfect fit, requiring little adjustment for a very tight/gapless finish. (7) The fuse interior is quite roomy and can accommodate a smoker system if you like. (8) The harware package is very extensive and complete. It even include a nice aluminum spinner, problably a $40 to $50 dl. value)

On the minus side [&o] I only found one problem area; (1) the horizontal stab is not mounted scale like. In the full size 232 the stab seats much higher in the tail, in fact is much higher than the engine thrust line and quite forward of the rudder hinge line. That arrangement provides a shorter stab moment arm, and is instrumental in the excellent tumbling abilities of the full scale CAP. This oddity of the Cap’s in general is not a good thing for the model Cap’s. Probably due to excessive roll coupling induced by the off centered pitch axis, most model CAP's with scale stabs tend to roll during violent pitch excursions (i.e. very tight and fast loops). The problem with the lower location of the stab is that the elevators interfere with the rudder linkage when one uses the longer SWB servo arms. I had to bend the link a little to clear the elevator on the one side since I installed a single rudder servo in the tail.

My CAP is powered with an Evolution 45GX. The radio gear will consist of Hitec’s Fusion receiver with an Electro Dynamics Research EDR-111 Pow'r Bus Pro, four (4) Hitec HS-645 MG’s on ailerons and elevators, two (2) HS-425 BB on throttle and choke, and one HS- 5955 TG on rudder. Receiver power is provided by two (2) FROMECO RELION 2400mAh LiIon packs regulated by a dual power Smart-Fly SuperRegulator with Pin type Failsafe switch. Ignition power is provided by a FROMECO RELION 4800mAh battery through a FROMECO Badger Failsafe Switch and a Smart-Fly 5.2volts Ignition Regulator. All power connections are Dean’s plugs with 18 gauge wire.

RE: GP Cap 232
 

Air Tech: Thanks for the loads of information and time you took to put it out here. I've been a member of RC Universe only a short time but am amazed at the wealth of information and to the extend most are willing to shared it. Folks like yourself , Bubbagates and Lou55 make RC Universe possible, again thanks!


Okay, that is one nice airplane! Not sure what most of the gear in the fuselage is , looks complicated compare to most glow models.....Funds are not an issue( I'm lying), technical knowledge is....or more like the lack of! :)) I ordered the Cap232/Fuji and it should be delivered TOMORROW, I can wait to get elbow deep and start learning! Hope you guys don't mind a few more question.

RE: GP Cap 232
 

That's also what makes the CAP snap. The GP Cap almost never snaps (never had mine do it) but will snap roll and 3D with the best of them. As for the weight. I just went from a OS 160 to a BCMA 40cc gasser and had no problem balancing the plane with either engine. I used the pull-pull for the 160 and put all the servos in the tail for the BCMA. Not sure why you would need or want the extra weight of a Fuji. Lots of wing loading. My BCMA weighs in at 51 ounces with ignition and muffler. You decide. The last thing you need is a lot of extra weight in a plane that is purposely built very light and handles great!!

RE: GP Cap 232
 

The 43cc Fuji will still have him around 14lbs. I thought the same thing when I had it in mine but the deadstick I had showed it still floated.

RE: GP Cap 232
 

Lou, how BCMA 40cc working for you hover vice, are you above or below 1/2 of the throttle? Any pics or vids?

RE: GP Cap 232
 

Haven't had chance to fly it yet due to weather but the break-in looks very promising. This engine will put out 20 pounds of static thrust with a XOAR 20X8 after break-in which is two pounds more then the OS 160 with the APC 18x6W. Right now it spins an APC 18x6W at 8700rpm on a 32:1 mix for break-in. The weight is not much different at 51 ounces as I ran a on-board glo-driver on the 1.60. As soon as I can get it in the air I'll post some video. It's all together and I'm going to try and get it out today. Hope it likes cold air!!!

RE: GP Cap 232
 

Got my Cap/Fuji in yesterday . This is a really nice airplane. The cowl had a crack about an inch long on the bottom side, looked like the box was dropped and a corner was accordion-ed a little right where the cowl was packed, anyway, one call to Tower Hobbies this morning and a new cowl is on the way! I did get a kill switch, after looking at the Fuji with the EI can I just use a regular RC radio switch between the battery and the engine instead of the kill switch?

RE: GP Cap 232
 

Here's RC 100 I used for the BCMA. http://www.rcatsystems.com/electronics/rc100.php You just cut the red wire mid-way on a extension and solder the two red wires in-line. Then plug the extension between your EI battery and EI unit. It runs right off of your receiver and works great. Light weight and solid state. I also bought the one from Tower and left it in the box.

RE: GP Cap 232
 

Weather turned nasty again so we decided to run in my 40cc in the CAP a little more. This is only the fourth tank through it. Here's the video.

RE: GP Cap 232
 

Hello, getting ready to start the wing on the Cap and caught off guard with the instructions. The control horns are attached to the aileron surface with wood screws and no back plate. Has anyone had any problems with this set up? I have gone over this thread a few times and have not read mention of any concerns.....or did I miss it? Thanks............

RE: GP Cap 232
 

Nope, no concerns at all. I'm well into 200 flights on mine and not a problem. Just screw the screws in, take them out, drop some thin CA into the holes and screw the screws back in.

Just an FYI folks. I now have 13 flights on mine with the new DX7 system and the DX7 is handling this plane very well. We have RF issues at the corners of our runway due to TV, Microwave and cell towers and this radio does not even flinch. Up to this point I have to use filters on everything even with dual conversion receivers because it could get bad at times but not anymore. I was using a JR2000 with a 10X previously. The only thing I wish is that the DX7 had better programming. Once you get used to having a premixes for dual elevators and rudder to elevator/aileron you kinda get spoiled;)

RE: GP Cap 232
 

I never had a problem. Just be sure and harden the holes with some thin CA.

RE: GP Cap 232
 

Lou55,
I am very impressed with the BCMA engines so far. A few friends at our club have purchased the 26cc and the 40cc versions, and they are proving to be very reliable. Most important it seems that BCMA provides excellent customer support for their products, and their prices are very competitive even against some glow engines. I feel the 40 would be an excellent choice (as you well can testify) for the CAP.

On the weight issue I am mostly speculating because I am not completlely done with mine. So far it looks like it may be a little tail heavy, but I can move my batteries up front, and may not need any additional weight after all.

RE: GP Cap 232
 

I have mine mounted forward. The EI battery is in the engine box and the receiver battery is forward of the servo tray. It seems to work very well. As for the BCMAs, they are great. They just discontinued the 40cc but are coming out with a new line called BCMA-MT Pro that will offer a 42cc. They also offer a 62cc based on Zenoah castings but much lighter then the Zenoah. The 26 is still available. Adam's service is excellent and he is more then willing to go the extra mile to get you what you need for your application. When I changed my mind about putting the 40 into my Christen Eagle he custom machined stand-offs for my CAP at no cost to me. Try and get that from DA, 3W, or Fuji.

RE: GP Cap 232
 

I was told at the flying field that I may need to go to a PCM radio in order to safely fly the Cap due to RF that the engine (Fuji) may put out due to the EI? Any thoughts? I have a 6ch JRSport FM......Anyone having problems with FM?

RE: GP Cap 232
 

Never ever use PCM to mask an RF problem. RF never goes away on it's own and only gets worse.

I've used 2 different EI fuji's and not once did I have a problem with RF as long as you remember the 12 inch rule which you can do on this Cap

RE: GP Cap 232
 

If you keep electronic ignition parts away from radio parts and take proper care that linkages arn't metal to metal you should be ok ... I never needed pcm in 10 years of flying giants with gassers.
Make sure you range test it with engine running

RE: GP Cap 232
 

Thanks guys! I'll stick to my FM for now. I'm in the process of gluing the point hinges to the ailerons using Gorilla Glue. I've never used the stuff, not sure if I'm putting enough. I did oil the center of the hinges and all seem to be going good so far. I'll wait till the morning to do the pull test.

RE: GP Cap 232
 

ricomary,

I never have used a PCM radio for my gas powered planes. Bubagates is right in that one must get rid of the cause of any RF interference before spending money in expensive electronics. Only time I was hit by RF noise was due to a loose spark plug vibrating and causing arcing that went right to the receiver.

I use an EDM EDR-111 Pow'R Bus Pro on most of my giant scale planes mostly for my own peace of mind. That's because the EDR-111 provides buffering and amplification to prevent noise and loss of signal when you are using very long servo lines and to isolate the power source from the receiver and servos. That's a personal choice, not in any way mandatory, as long as you don't have any source of RF interference.

RE: GP Cap 232
 

hey bubba, i just got my da 50 sitting in front of me, and i was just wondering How the heck did u work out the thrust line to put this motor on the GP cap.... and the bolt pattern??

RE: GP Cap 232
 

I put my EI unit on the left outside of the engine box and wrapped it in 3" aluminum foil ducting tape for further shielding. Don't have any problems with RF interference but it sounds like you may be getting outside interference. Pretty hard to control that without PCM. Ask your club members if they have tried any other fixes for the outside RF they are experiencing and make sure you program a failsafe to cut your engine if you do get a hit. Be careful with that polyurethane glue, it foams up quite a bit.

RE: GP Cap 232
 

The Cap is on the bench being built, not at the field. The big gasser pilot's at the field recommended that I use a PCM, they fly the BIG gasser 96 to 120 inch with DA-150's. The inside of their Fuse looks like an electronic store, very intimidating to say the least. Any way, putting things in perspective, my Cap is much smaller and will be set up for sport flying (not 3Ding). I didn't think it was necessary to jump on a PCM when I have not had any problems yet. I do agree that any bad RF should be fixed and not masked by the PCM as mentioned by Bubbagates, makes sense to me. The guys at the field are great guys and really know their stuff when it comes to the big one, I'm just don't think my Cap is in their class and needs the very top of the line equipment....I'd like to keep it simple, safe and enjoyable for me. Y'up that Gorilla glue does foam up :))

RE: GP Cap 232
 

Aussie

I have a template that you can use. You can download it from here

http://www.hiddenhangarrc.com/pdf/DA...l-template.pdf

RE: GP Cap 232
 

I just finished my Cap 232 with the FX1.60 engine and Pitts muffler. It was just a little over l2 lbs. I was supprised with the light weight. Mine usually come in a little heavy as I do a lot of re-glueing. Everything fit well. Hope it flys a well as it looks.
Bob[sm=lol.gif]

RE: GP Cap 232
 

Bob,

Here is a video of one a friend of mine had with the same setup you have at the same weight

http://www.hiddenhangarrc.com/video/...vincentcap.wmv

The 160 definitely flies it well

RE: GP Cap 232
 

oh thanks bubba,
maybe another dumb question about the da, The 4 Bolts hold the prop on and the one Bolt thread is for the spinner right..?? The bolt that comes with the cap ( Spinner ) does that fit on there.??

RE: GP Cap 232
 

Bubbagates, I just mounted the Fuji to the firewall and it's 9/16 too short front to back of firewall. What did you use as spacers? Should I also use a fender washer on eadh bolt between the engine and firewall to spread out the bolt pressure over a larger area of the firewall?

RE: GP Cap 232
 

:)ricomari...

If I have to make spacers, I make them out of lite plywood. Just make them about the size of a nickle. Drill them first and then glue them to the firewall. Works very good and is very solid.

Thanks
Barry

RE: GP Cap 232
 

ricomari,

What Barry suggested works well. Yep, you do want fender washers to help spread the load out. I had some 1/2 aluminum spacers left over from aseembling an Aeroworks Yak so I used those and just moved the cowl back 1/8th inch. If I remember the manual correctly you have about 1/2 inch of play with the length from the firewall to the prop shaft. If it is a bit shorter than the suggested length just move the cowl back a bit

Aussie,

The cneter prop shaft is threaded for a 10/32 bolt which comes standard with most every aluminum spinner I have ever seen

RE: GP Cap 232
 

hey bubba, im just curious.. u have the Yak 50cc from Aero Works. i just bought the Extra 50cc. i was wondering if you could possible tell me ur setup.?? Im not sure if i should run a Power box sc 12 to power my servo's im going to be running 8611 all round
or just stick with the Lith ion and regulators ??

RE: GP Cap 232
 

Aussie,

I saw you thread and questions on that plane

Here ya go

AeroWorks 50cc Yak red version
3W 55i on the 3W aluminum "S" header and KS1060 tuned pipe
PT Models 23x8 prop or the Vess 23b depending on what I'm flying that day
3.5 inch Pete's CF spinner
JR8611's on all surfaces using SWB 1.5 inch control arms everywhere and H9 Pro-Links on everything. Stock pull-pull on the rudder
2 Fromeco 2400's through Badger switches going into a Smart-Fly Super Regulator that then goes into the Smart-Fly PowerXpander
1 Fromeco 2400 on the ignition through a Badger Switch, no regulator as 3W engines do not need it.
JR2000 receiver and a 10X for guidance
Stock control horns
Stock fuel and smoke tank
Sullivan Skywriter smoke pump using a Li-Poly 11.2 volt battery

Total weight with everything above installed is 19lbs 4 ounces

If I remove the spinner and wheel pants it's 18lbs 14 ounces

If I remove the smoke pump and battery along with the wheel pants and spinner then I'm down to 18lbs 9 ounces. I'm not including the prop weights because they both are exactly the same weight. The CF prop gives me great 3D. The Vess wood prop pulls like there is no tomorrow and nice slow downlines so it works well for IMAC sequences

Vertical is really good but not unlimited with everything on, remove everything like I mentioned and it now becomes unlimited. It does not go uphill in a hurry but I can get 3 deep snaps and it will keep on truckin' going straight up.

BTW... other than what I listed above, everything else is stock

Now, the reason I use the Power Xpander is for the filtering it does. Where I fly we are surrounded by cell towers, TV and microwave towers. We get RF on occasion due to all of this. It's not bad but I'm not about to risk planting a GS plane

We used to have IMAC meets. The last one was in 2001. I was not a member at the time but the way I understand it is that year is when most of the cell and microwave towers went up. The last meet saw 6 very expensive planes go down due to the RF so when they tried the next year no one came.

It actually has gotten quite a bit better, both TV stations are in the process on moving, one is already gone and things really improved. The real thing is it is such a nice field for the area I live in with tons of flying room.

A couple of us are currently looking into some ground that one of the guys knows about for our own field to fly our BIG toys at without having to worry about RF issues. So if that does come about then on 50cc to 100cc planes I would not worry about using any type of power box

Now that I said all of that, this Yak will be going away. My girls and their husbands got together and bought me a Comp-Arf 3.0m Extra 260 Kiwi scheme for Christmas and this is after I bought myself the Comp-Arf 2.3m Extra 330L for Christmas. I need to sell off a few things to be able to get the equipment I need to get the 3.0m flying.

I've had 3 people very interested in the Yak since I mentioned it to them. All three have either actually flown it or saw it fly. It's a typical Yak, they all fly the same. I actually had the 50cc Extra on order since the Toledo show. There was a mixup on AW's part when they came in so by the time it weas realized, the first run was sold out. I did not want to wait for the next run so I cancelled the order. AW did everything they could to make me happy, but by the time it was all said and done I just was not going to do it. In hindsight, considering what my kids have done, it's best anyway

RE: GP Cap 232
 

oh thanks you so much for that Bubba,
Im going to run the 8611 on every surface and im also going to use the Fromeco 4800 lithium for reciever and im going to use the Powerbox Champion 40/24, with sensor switch just for the servo's so they can get full power all the time....thats basically it hehehe and im going to run my da 50 in it inverted pitts style muffler with smoke im just contemplating right now as we speak if i should use the fromeco lith ion batts or go with 2 big NiMH batts they plug straight into the power box and regulate the servo's at a constant amp.
oh decisions decisions...
Are Lith ion batts the same as lipoly battery

RE: GP Cap 232
 

guys
a friend of mine just got this CAP
HW as follows:

servos - all hitech 5645/5695rudd/645TH
engine: MOKI2.10
FUT 9CAPTX\8chRX pcm

here is my Q?

does the moki will do the work? - F3a?
would it do 3D???

please advice?
thx

RE: GP Cap 232
 

GADI,

Yep, the Moki 2.10 will be plenty and then some. There was someone running the same engine near the beginning of this thread and the last I heard from him it was absolutely a great match

RE: GP Cap 232
 

hey is lipoly the same as lith ion batts>??

RE: GP Cap 232
 

Bubbagates, the 1/2 inch aluminum did the trick. Do you know if I'll have to cut the spinner if I use the PT CF or TBM wood propellers. I ordered the APC 20X8 prop that Tower Hobbies recommended. I don't want to use it, maybe except as a spare or above my shop door! Thanks
