On several occasions I have substituted such cranks with metal control arms. File a flat area on the rod and use loktite, and make sure to check regularly

Metal control arms

Someone had one of these at my field today. Looked great on the ground and flew amazing. Only issue with it was the pilot was powering it with glow so I could not see how it worked as a EP flyer.

I have one with an e-flite power 60 in the nose on 6S. Flies amazing! Very quick. I have had it a bit over a year, and the only problems I have had with it is from the e-flight electric retracts.

I am running the same setup here, power 60 on 6s using a 16x10 zoar prop. No complaints at from me. Flies with good power and authority. So far the retracts have been holding up pretty well for me, though I think I may have squeezed one of the struts with the little allen bolt in the gear door mount. The strut does not compress very well now.

Just finished putting mine together. I have it setup for both inner and outer flaps but having some trouble setting up the radio programming to get all 4 flaps working in unison. The outboard flaps are working fine as they are assigned to the FLAP SYSTEM channels on my JR 11X.

However, the inboard flaps are each assigned to their own channels then mated to the FLAPS. Whats happening is when I hit the flap switch, the inboard flaps are not in sync with the outboard flaps. Matter of fact, the two inboard flaps are not even in sync with each over.

Any suggestions on the best way to set this up? Should I just tie each inner flap to their respective outboard flap via a y-cable and just mechanically try to get the inboard flap to be in alignment with the outboard flap?

Any input would be greatly appreciated.

TIA,

hk

You could probably make these work with minimal mods:

canopy

Anyone have trouble getting the canopy to fit properly. If i have it down in back and on the sides, it stick up about 1/8 of an inch in front. If I push it down there, the sides buckle out. It seems like it is not molded in the correct shape to fit the plane.

Thanks.

look for something interfearing with it in the middle of the hatch.

Canopy

Nothing interfering, just a bad fit I think. If I put the front down flush, the back is in the air and vice versa. The canopy requires bending to get both the front and back to fit flush.

You can VERY carefully heat the canopy with a heat gun while in place on the fuselage and greatly improve the fit.

Thanks Craig. I had thought of that but it will be a last resort. I'm putting this together for a friend and envisioned a blob of molten plastic or a hole melted in it.

I've done it on a couple of them but just to get small gaps to sit down. The temperature where the plastic transitions is reached suddenly, so care is needed. At that point the only warning is that it will begin to wrinkle slightly, the heat must be removed or it will get pretty bad in a hurry. Once it is barely wrinkled I use something like a tongue depressor to push it down and close the gap until it cools.
