One suggestion on the UCANDO covering is to use a seringe needle and go thru the wood in to the hole where it makes the bubble to le the air out so it can strech, don't do it on the covering with no structure(I guess everybody nows this anyway), I just built my second UCANDO after the first one crashes (during an inverted low flyby corrected to lower more and I had an interference between the brain and the finger "I was flying in 3D rates!"), and this model flys as well as the first and I have almost no rudder coupling (YS 91, all equipment in the back (under the wing),I will measure the CG today, never ripped a gear, so I don't know what is going on with the rest my two kits were good and straight, my only suggestion to those with problems is to really check angles and distances with a string and an incidence meter, remember if the aileron have some ofset even if it looks right it will have rudder coupling, when I mean no coupling I mean that I do low knife edge flybys at half throtle with only slight corrections because of the wind, etc.

If you guys are looking for the best in craftmanship I can only recommend airplanes from Top Model like the Diabolic, I have never seen an aircraft with this finish is absolutly perfect, when I received mine I really looked for defects and could not find one, I'm very good builder and I guess most of you too but I can assure you there's no way to do it better than that. Hope this can be useful.
