Assembly was very easy and the parts all fit up well. I used Gorilla glue throughout as CA just does not have the needed strength (IMHO). Initially balanced per the instructions, and it was tail heavy. Added 1 oz of lead to nose above the battery, and that seemed to work much better. With the flap servos configured, needed to assign L flap to one channel, R flap to another channel via Spektrum DX9 TX and 6-channel RX. I put a Dynam 13 x 6 prop on and this gives much better vertical performance. After initial flights added a HITEC gyro, 7 channel RX, and this combination works well. I initially glued the wing tips with Gorilla glue, but this was not adequate and they came off in flight. Revised the wing tip attachment by using bamboo skewers inserted into the wing ends and the wing tips, and this arrangement has survived some rough landings and aerobatic maneuvers. It is a bit sensitive in pitch, and I plan to try a reduced elevator throw for landing in particular. I get about 10 minutes of flying by allowing at least 1/2 minute between any full-throttle maneuvers. Overall good value and fun to fly.
