Beavertail, definately agree with you. I honestly think vectorflight airplanes are probably one of the best I have seen. Also maybe the least known on this planet! Dont know why they dont advertise much.

I would recommend using some epoxy to beef up the firewall from the inside in case you still want to use a larger engine, and make sure the tailplane is glued strong. I only had maybe 1 degree down thrust and that seemed to work great for inverted.
