Mine built very well. Jerry's plans were very good, though I didn't like his linkage set-up on the flaps and dive brakes. I ended up putting seperate servos in for the left and right sides. With full cockpit detailing and 12 servos, finished weigh is about 40# dry. The G-62 pulls around nicely in the air at about 1/2 to 2/3 throtle; though it's a little sluggish on takeoff. I think a 3-bladed prop would help, I just haven't had a chance to try one yet. I used Bob Holmann's laser cut flap kit, and would recomend it if you're going to replicate the perforated flaps. They are very effective in air, but the plane is very stable in a dive with them deployed.
