Thanks again, you have been very helpful to me.

Thanks to Twisted Hobby's fast shipping, my Yak55 arrived yesterday and I already have it built and flying! Using HXT900 servos for control. A KDA 20-22L motor and Hobbywing 18amp esc with APC 11x4.7 prop used for power. First flight was a few hours ago at dusk and it flew beautifully! No trim was needed and I was already feeling confident enough to hover close down, and do rolling harriers on the deck.

CG is about 100mm from the LE. The throws are maxed out, and I'm flying without expo or DR programmed yet.

This is the perfect 3D banger I was looking for. Thanks RCF and TH!
