That looks really nice, I'll bet you could use thinner carbon sheet on the sheer webs and the top plate to save a little weight. I like it much better than my FPV250 from HK but at least it was cheaper. I've only used one other commercial frame and that was from Rusty.
This is Kiss Esc Emax 1806 with 5x4 HQ props Quatos R432, I am using the pre-load with reduced preload values. It's got BT, 5.8 video link with MinumOsd and camera tilt. Since the risk is so low I find I fly it a lot with a remote 5.8 receiver and a outdoor Spektrum antenna.
I consider it very heavy at 500 grams but fly's at a throttle factor of .5.
Cheers
