RE: GP CAP232 Build
Well, you asked for tips and the time is now. I highly recommend strengthening the gear mount. After having my gear removed by a fast landing on a grass field, I had the chance to rework mine. Using the scrap plywood from the fuselage doubler as a pattern, I made an 1/8" thick plywood tripler that extended from F-3 forward. This gives the landing gear base a larger gluing surface to adhere to. I also added corner gussets where the base meets the tripler.
Also, instead of installing the 8-32 nut insert, install 1/4-20 inserts and use nylon bolts to secure the landing gear. 1/4-20 nylon bolts are more than adequate for this plane, they will withstand any landing the stock landing gear mount will.
