RE: H9 Extra 260 quality?
I tried one with an Evolution 26. Not enough power. It was VERY light though so it flew very good, just not enough power. I think it was just a tad over 12 lbs.
I think a very good glow engine would make performance spectacular (YS 160 DZ on 30% nitro) and still have reasonable weight. 1 servo on each surface and 1 good battery with 2 wires and 2 switches. Makes for a very expensive setup but quite simple.
