I've got mine at 6 1/2" with no snap at all. That said, I built mine ultra light. It comes in at 14 lbs 10 oz. with smoke system.
So the fact that it does not snap and did not need a lot of roll/pitch/aileron mixing may be partly due to weight.
To give an example of what it will do, I can come straight down the runway at 20' 3/4 throttle, chop throttle slam the elevator full rate back to go into a wall, as soon as it's vertical slam the stick full forward and it will pivot 360 around the cg and back into a hover.
I'm not a great pilot, only fly 3 or 4 times a year (if I'm lucky).
It is also a very easy plane to fly knife edge and to do nice 4 point rolls with. Another manuever it does beautifully is a Lomczavak (sp?).
Yep it's a real sweatheart. It would be a complete redesign to do plug in wings and it would have to be heavier to do that. Same with the removable hatch. I wasn't going to add smoke, but I came out so tail heavy it was either put in smoke or add a pound of lead to the nose. Smoke is so much cooler!!!!
Happy flying,
Scott
