mups53, I saw the prototype on a high dollar set of digital scales at the Lanier/CGP factory. RTF weight (dry) was 4.8 lbs. This is with a YS63 and Futaba 148 servos. The use of mini servos would get the weight down even more. Performance at this weight was exceptional. I really like the bellcrank set-up on elevator, eliminating the wire elevator joiner.
