The U-Can-Do 3D is not mine. Here at State the RC Club has a few room to store/work on RC airplanes.
The mistakes are very miner (messed up cuts, stuff not fitting right the first time, buying new wood, ext.) nothing that I think will effect its flying. As to the comment about taking months, this kit went together very fast (a little to fast for my liking) but very straight. (Its not done I'm thinking ~1 week to cover and ~1 week to get every thing ells finished)
