I haven a super chipmunk that i just built but i was wondering if 2-56 rod is sturdy enough for this plane

If you mean for the split elevators and the rudder, I would say yes. If you are planning on doing some serious aerobatics you may want to upgrade to the system you like best.
I haven't had any problems with mine so far...

I used the included push rods. However after a couple of flights I opened up the bottom of the fuse near the stab so I could put a bearing support on the elevator push rod. I was getting a lot of flex at the Y. Very nice flying plane. The retracts are a pain. If I had it to do over again, I would get the fixed gear version.

jabowil,
What's the problem with the retracts? I didn't know they had both versions. I had thought about converting the retract to fixed.

The 2-56 are not enough. i had about 20 flights on the and could not figure out why i was falling out or loops, and why they would get flat at the bottom, as well as twiching up and down at level flight. Then I changes the elevator push rods to 4-40 with a hard wood dowel and glassed it. MUCH BETTER. The rudder replace with a 4-40. I am at about 50 flights and can't imagine life without this plane. If you ahve any questions let me know.

You can order the Chipmunk with fixed gear, comes with nice fiberglass wheel pants. Also saves about $20

I recently put together one of these models.....I installed a Saito 91 (inverted), hooked up the flaps, installed a Dubro remote glow starting device, used 2-56 all the way, the retracts are a delight, and the plane flies great. I did however use Hitec 605's for the rudder and elevator. It's total weight is 7 lbs 6 oz. It will weigh about 7 lbs 2 oz when I install a lighter battery. I'm usually cautious about putting larger rods in but saw no need to for this aircraft.

Hey Boisebee,

The plastic housing on my original set broke on the 2nd landing. Replaced them with some metal ones. The struts bend a lot and require frequent bending back in shape so they will open and close OK. This rebending is pretty hard to do. I guess to me they are just more trouble than they are worth. If you fly off a pave surface and have good smooth landing skills, they are probably OK for many people.

Thanks jabowil. Sounds like 5/32" wire. Planes which weigh 8lbs or more need 3/16". If 3/16" wire will fit in the retract, that may solve your re-bending problem.

does anyone have a link to the WM chipmunk with fixed gear?

Thanks,
WOOD

try www.airborne-models.com

sorry, but I opnly see the one with retracts, where is the chippy with fixed gear?

just call and tell tem you want fixed they sell at the same price! There is another company that sells fixed for less but i cant remember the name right now.

go here and check out the chipmunk. http://www.winnerrc.com/Arfairplane/...RF.htm#Comment

thats the web address i was triing to think of they are about $20 cheeper on fixed gear

Well i just went there and they are no longer cheaper for the fixed gear sorry!

For those that may be having problems with the retracts on the WM SuperChippy check out a thread entitled: Retracts: How to Cure Nose-Overs and Bending Wires.
I believe the last post date was 4-8-02.
