World Models Super Chipmunk Setup??
 

Hello all, i have a NIB world models Super Chip and a NIB OS Surpass 92 for the business end of it. I would like to set it up with a smoke system. I need some help on what you all think would be my best choice for a pump and such. Any ideas would be welcome.
I have never used smoke before but i have been asked to perform a RC show at our town's summer fair in july. I would like to have lots of time to make sure that i get the plane perfect before then. It is -25 degrees C and we have several feet of snow and lots of wind. I am going to spend the next while building airplanes to keep from going stir crazy. Well that and watching RC videos on youtube.

Sorry I can´t help you with the smoke, but want to congratulate you, you have bought a fantastic plane. Powered with that OS 4 stroke will do everything. I have it since end of august and have done more than a hundred flights.

Unfortunately I did not use a 91 4 stroke, but a 60 2 stroke, although powerful moves a 12x8 and the 91 would move a 14x8, with that, verticals should be unlimited. In fact I am thinking in buying another one to put there a 91.

Lots of luck with your show and your plane, the "chippy" will not dissapoint you at all. Hope you find a good smoke system.

Regards, from Spain

This should prove a very interesting thread. I too have this plane, powered by a Saito 100. I would love to add a smoke system to mine for the show aspect. I'll be watching![sm=what_smile.gif]

Right now i am way busy managing the senior hockey team and my son's peewee hockey team to get started on it. But hockey should be done in about 2-4 weeks and then i will have time. I just thought that if someone had ideas i could purchase all the things i would need and be ready to go. When i get working on a plane i get tunnel vision. This usually happens right up until my wife smacks me in the back of the head!!!!! Just a love tap mind you to remind me about the fact that i'm not paying attention to her and the kids!! LOL

RE: World Models Super Chipmunk Setup??
 

OK hockey is over and it's time to get started. This will be a slower build as i won't have a lot of time during the week-days to work on it. Tonight all i did was pull the box out and check to make sure all the parts were there. I have to say that while the box that it came in was mashed up good i was really impressed with the quality of the plane and the hardware that came with it. One thing i will be changing is the pushrods, they are really stiff and don't take a bend well. I will swap them out with some softer ones. I did epoxy on the servo mount blocks to the aileron hatch cover, and read the manual several times cover to cover. Now is the time to chime in with what smoke system you are using and if you have any ideas for mine. I have never dealt with smoke before.

RE: World Models Super Chipmunk Setup??
 

I should mention that this box has sat out in my garage the entire winter with temps ranging from -5 C to +20 C depending on if i have the heater running out there and the covering was beautiful, i have one small sag that i will hit with the iron and other than that it is mint. Even the manual is decent which is saying something coming from China. Thats it for tonight

Wait till you try the KE on this baby ... she is one of the finest scale planes I have flown. I had 2, 1st was powered with a ST90 and 2nd was in EP then with a YS110. Just take some care when you install the tail wheel, please cut a recess/trench for the wire to sit along the bottom of the rudder.

RE: World Models Super Chipmunk Setup??
 

I have had one for 2 years, really a fun airplane. Recently bought the gp version. The only thing I changed out of the whole box was the fuel stopper for a sullivan. Fly's with a magnum 91 4st. and 14-6 prop. Never have used the flaps, dont need them. KE's are extremly easy, goes where you point it. Will have to get another, hide it for a spare.

RE: World Models Super Chipmunk Setup??
 

Ya this is number 2 for me as well, the first one is in more pieces that it should be due to a take off stall (totally my fault). It had an OS .61FX in it and flew beautifully. I should be able to do a bit more work on it tonight. Was messing around looking at the wing and when i held the 2 wing halves together tight at the front and as tight as i could at the back i had a small gap at the back. Should i just sand it a bit until it is flush or does anyone else have any ideas to cure it. If it is not tight at the back i am betting that the wing mount screws will not line up right.

flyboy76

RE: World Models Super Chipmunk Setup??
 

Flyboy - small gaps are ok, when the holes for the bolts line up. If you are not comfortable with it then why not just add some wood dust with epoxy and fill her up.

RE: World Models Super Chipmunk Setup??
 

Sounds like a good idea to me. I didn't get a chance to work on it last night but i plan on getting the wing together tonight.

RE: World Models Super Chipmunk Setup??
 

Flyboy, I still intend to get you a pic of my inverted Saito 100 installation. I used a fuel dot and remote glow adapter as well. It's a very neat setup.

RE: World Models Super Chipmunk Setup??
 

I had one of the very first Chipmunks from World Models way back when, I lived thirty minuets from the distributor, Airborne Models in Livermore that supplied Sheldon's Hobbies which was twenty minuets from me in San Jose.

The Chipmunk is a very good flier and construction has come a long way from the first generation birds in that they no longer use "hot glue" like in the retracts on the one I had.

I used a inverted Super Tiger 90-K with a "war bird" in cowl muffler from Top-Flite, seemed to be a perfect match.

I don't recall just how much room is in the fuse for smoke but don't go over board with the tank, eight ounces should be enough for show work. I used a 12 oz. tank in my Goldberg Sukhoi with a Webra 120, 12 oz's of smoke oil and 16 oz's of fuel made for some harry flying for the first five minuets or so till the plane lightened up a little.

It was so long ago I can't remember the name of the smoke pump but it plugged into my receiver, any switched channel except retracts and had it's own 600 mil battery.

Good luck.

RE: World Models Super Chipmunk Setup??
 

Ya i was thinking that with dual aileron servos flaps and such i would just run an extra battery pack and using a y harness plug the retracts and smoke pump on the same servo, when the wheels are down the smoke is off and when they are up the smoke is on. I was also thinking i might rig it up with my throttle servo and when the throttle is over 1/2 the smoke would come on. Not sure but an 8 oz. tank would be tops in my eyes. Lots of ideas and a little while until i am there yet.

RE: World Models Super Chipmunk Setup??
 

Got the wing epoxied together last night and used a couple of clamps like it showed in the RCU review. Worked pretty good and when i trial fitted the wing the bolts lined up just right. also got the aileron servos and flap servo mounted and hooked up. Also got the tail feathers epoxied in place and will start work on the control horns and linkages once i get a chance and i will glue the servo tray in and start on the engine mounting.

RE: World Models Super Chipmunk Setup??
 

I installed smoke in my cg pitts monster, my first smoke install. i used the sullivan skywriter pump, 8 oz tank, and a bme smoke nipple. I drilled and tapped the exhaust pipe close to the cylinder head and installed the injector. Some people wrap tubing around the pipe then into it for maximum heat, i didn't bother. i have the pump set on channel 5 at about 50 percent atv to get this smoke with my saito 150. Will smoke for 5 min. Just watch your weight on the chippie. I bet with full 8 oz tank, lines, pump and auxilary battery, you will be adding close to a lb.

RE: World Models Super Chipmunk Setup??
 

flyboy better come in with some speed or with full flaps! Maybe can try a harrier landing!!! :)

RE: World Models Super Chipmunk Setup??
 

I will only be using a 5 oz. tank as i don't want to weigh it down to much and i am hoping to slid it in under the fuel tank if possible. I was looking at the sullivan as well and will probably go with that.

Flyboy76

RE: World Models Super Chipmunk Setup??
 

Got the retract servo mounted and hooked up, and got the servo tray glued in. Also trial fitted the 91 on the front and drilled the engine mount holes. The only thing that has been a pain in the butt to date was when i was epoxeing the tail feathers in place and trying to get the tail wheel in place and glued as well, other than that this has been a pleasure to build. This will be my first 4 stroke so i am really looking forward to it.


Flyboy76

RE: World Models Super Chipmunk Setup??
 

Yeah ... the tail wheel is a pain if this is your 1st time, that's why I said to cut a notch for the wire to sit in and also to do dry fitting first before you try to glue it.

RE: World Models Super Chipmunk Setup??
 

I did all that like you said i was just commenting that even with that it is still a pain. My first chippie had the wire come loose and that was a real challenge to get a notch cut out and then glue it back in after. I will get a chance to work on it more on Sunday and i hope to get all the servos in and control rods hooked up.

Flyboy76

RE: World Models Super Chipmunk Setup??
 

Having fun with the elevator push rods? Heheheheee ... that's about the last problem.

RE: World Models Super Chipmunk Setup??
 

Ya i remember from last time they were a real pain because you have to bend them out so they will exit the fuse but you have to squeeze them together in order to get them to the back of the fuse through the formers first. Any tips on how you did this. I have been puzzling on it. IF there was a weak spot in this plane as far as building i would say that this is it. I am thinking about running seperate pushrods and tying them together right before the servo.

Flyboy76

RE: World Models Super Chipmunk Setup??
 

Tips? Well the only one I can think of is to use 2 HS81 MG servos!

RE: World Models Super Chipmunk Setup??
 

As in mounting them at the back of the fuse? Not sure what you mean.

Flyboy76

RE: World Models Super Chipmunk Setup??
 

Got a bunch more work done last night on the chippie. got all the control rods in place and hooked up got the engine mounted and throttle set up as well. I will take some pics tonight but i bought a 6oz dubro tank for the smoke and it fits perfectly between the servo tray and what would be the bottom of the cockpit. Also got the charge jack power switch mounted and installed the reciever. That sponge with the cutouts for the reciever and battery is a nice touch. The list of things to do is getting shorter

RE: World Models Super Chipmunk Setup??
 

got some more work done last night. Good thing the wife has crafts she wants to work on out in the garage, this way i can build and we can still spend time together. Anyways got the pilot and canopy on but i am thinking i should add some clear tape at the front of the canopy or put a screw there as my last canopy ripped off in the wind due to the front lifting. Also got the cowl cut out and installed. I was a little worried and i haven't had much luck in the past with cutting and fitting but i am ok with how this one turned out. I had a bit more to work with as i still had the old canopy from my crashed chippy so i slit the side of it and used it instead of the clear plastic one. I am having trouble uploading pics from my work computer so i will give links to my photobucket album. The wires are quite messy right now and i still have to run the tubing for the smoke oil tank and install the sullivan smoke pump but the end is in sight. I set all the control throws as well. I just set the spinner and prop on for looks but will be replacing it with a chrome spinner and a black master airscrew prop with red tips, should look good. If things go well and the weather cooperates i should be able to maiden it this weekend. Getting pretty excited.

RE: World Models Super Chipmunk Setup??
 

Flyboy - you should have gone inverted ... that hole is really big! :)

RE: World Models Super Chipmunk Setup??
 

I am ok with it. I did cut away a little more that i would have liked and i could have ran the muffler inside the cowl pointing out the bottom and cut a lot less out but this is the way i did it so what's done is done. I am by myself tonight so i should get it pretty much finished.

flyboy76

RE: World Models Super Chipmunk Setup??
 

Flyboy - wait till you see me do a cowling job, its PERFECT ... A PERFECT DISASTER!!! Its like the Texas Chainsaw Massacre ... I can build ok but I have no finess for cowlings.

RE: World Models Super Chipmunk Setup??
 

got pretty much everything done tonight. I need to break in the engine and install the smoke pump when it arrives. I will have to add a little weight to the tail to get it to balance but i will wait and fill the smoke tank before adding anything.

Flyboy76

RE: World Models Super Chipmunk Setup??
 

Swapped the empty tank and the reciever/battery pack around and that did the trick as far as balancing goes, plus the smoke tank is right on the CG so it won't make a difference if it is full or empty. Ran a couple tanks of fuel through the 91 last night does it ever sound awesome. This is my first 4 stroke and i have to tell you i think that is the end of the 2 strokes for me. Anyways here is a couple pics, i had the assembly engineer with me as well. She love planes i am going to get her a rubber band one to play with. IF it is calm tonight i will maiden it right now the wind is blowing pretty good. Going down to the lake today to open up the cabing i guess i had better get my beaver on floats ready to fly. Spring is officially here!! IT's about time!!!!!

Flyboy76

RE: World Models Super Chipmunk Setup??
 

Flyboy - please get us some pics of the pouring smoke! I got a nephew and he is just over 4, he gets to keep my slighly damaged EP planes ... he always promises not to tear them apart but he has been lying to me for the last few planes!!! Hope to get him flying soon too, maybe when he turns 6. Wanna hook him up with your daughter? Hahahaa ...

Here is a pic of my No. 2 Chippie on its maiden ... noticed how nice my cowl is? :)

RE: World Models Super Chipmunk Setup??
 

Great looking plane Flyboy! Yours too Tianci. I too have a couple of pride pics as well as an "assembly engineer". :D Let us know how it flies!

And although it's a little late, I am adding a pic of the inverted mounted front shot.

RE: World Models Super Chipmunk Setup??
 

[img][/img]Trying to upload a pix of my chippie, flyboy I think you need to put a elmo pilot in your chippie, I am sure your engineer would agree

RE: World Models Super Chipmunk Setup??
 

Nice pics guys, hopefully tonight is nice and calm. Was down at our cabin this morning and the ice is starting to come off the lake a little already, so i'll have the get the engine back into my beaver. Hindsight being what it is i should have mounted the engine inverted but i am happy with how it looks. The smoke pump is supposed to be here on Monday so i can mount it and program everything and hopefully tuesday night i should have a smoke show. Anyways cheers for now

flyboy76

RE: World Models Super Chipmunk Setup??
 

I still haven't maidened my Chippie the wind never came down and i would still like to run another tank through it as well. Man that thing just purrs. I spent today working on my other chippie a Nitro models one that i bought used after the owner had a really rough landing and messed up the landing gear and cowl. Just about ready to mount the engine and then it will be time to order another cowl and landing gear. Cheers for now.

Flyboy76

RE: World Models Super Chipmunk Setup??
 

I've been flying my WM Chippie for 5 years with a YS 1.20. It has never flown as good as my Goldberg Chipmunk(s) due to weight issues. So...I re-engined it with an OS .91, removed the twin elevator servos and put in an MK elevator crank from Central Hobbies. I could not make myself do the elevator pushrod thing, way too flexy for my taste. I also got to take out 5 oz of tail-weight. In total, I removed nearly 3\4 Lb. so I am excited about the way it should fly now.

Good Luck Flyboy76 on your maiden!

RE: World Models Super Chipmunk Setup??
 

The elevator pushrod has bothered me as well, but the first one i had didn't have any problems so for now i will go with this. If i feel i am not getting enough authority i will swap it out for something more rigid. I was considering dual elevator servos but would prefer not to do that for weight reasons. On a pos. note my smoke pump showed up today so i will be installing it tonight and hopefully will have a chance to try the smoke out.

Flyboy76

RE: World Models Super Chipmunk Setup??
 

Here is a pic of the MK elevator crank on another airplane of mine. Simple to set-up, but with less weight and more rigidity than twin pushrods.
