 After upgrading the rear wing support with a piece of wood, I am finding that my wings are now taking the damage on either side of the rear plastic piece that the rubber bands go over. The wings are wanting to move vertically, and the foam is shearing. I'm in the process of stiffening the wing with a small piece of plywood. If it works I'll post pics. Is anyone else having this issue? |

Yeah. that's a weak spot. I used tape on my old Cub. I covered the new one with epoxy and it hardened it.

I just covered the middle of my wing with some cloth tape to prevent any damage to it from rubber bands or the cub's fuselage. Well, my last wing anyway, my new wing is just coated in profilm.

I may go that route when I can stop crashing - my biggest issue us that all the convenient locations for me have trees and houses and mailboxes and light poles. I would put a piece of styrene under the plastic on top and bottom before covering with film. |

Here's the portion of the wing that I grafted in new foam from an old wing I had laying around. I took a fresh piece of foam from the outer portion of the wing. Of course, there's no molded in bend, like the original. The packing tape, covered the seams, and kept the white Gorilla glue from foaming up too badly. (sort of) You can see the seem just outwards of the plastic brace, on both sides.  |

And here's the underside of the wing. There are two strips of very thin plywood running side to side. The one on the back of the wing runs from aileron to aileron. The one just forward of that, is just wider than the fuselage. One pic has the two pieces outlined for clarity, and the other is just a picture of the finished product. Now, the plywood edge rests against the plywood reinforcement to the saddle. Hopefully the rubber bands will still allow some give so that the fuselage is not destroyed next time I run into a pole or crash, etc....  I haven't flown it yet, because I am still waiting for my ESC to arrive from the crash that necessitated this rebuild. And yes, I know the wheels needs straightened.    |

Thanks CB! I have yeat to fly it, as the engine and ESC was damaged in the crash that caused me to do this repair, due to not turning of the throttle and the prop was trapped between a tire and the ground. I have the replacements, so it's just a matter of some wood working to get it back together now.
