Tailspnr, I'd be very interested to see the results of putting a DA50 on this plane. Be sure to report how it goes. From my experience with my DP Extra w/ a run of the mill 50cc sachs, total weight close to 16lbs, the power was crazy enough 1 click of throttle was the difference between hovering and pulling out. DA 50 produces even more power yet. I've seen a few videos of DA50s on even heavier planes such as the Kangke Laser2000 and Wildhare Extra special, both planes weighing 17lbs and over, both having STRONG pullouts out of a dead hover.

Chip's video shows a O.S. 1.60 FX whipping the plane around like mad. I guess what I'm getting at is that it seems the DA will be unmanageable power when bolted to this plane. Hope you have good results however!
