Wow, its been over a year since this posting started. I will say that the 40 % Extra exhibits excellent 3D characteristics, and is quite stable in both upright and inverted harriers. Very little wing wag and I've come down on the learning curve tremendously with this airplane. Interesting, I've been tracking the 33% version as well, and the pilot has moved the CG back quite a bit. Yes, he has the hovering and torque rolling down to about 3 to 4 feet consistently, and he (Bill) does not show much wing waggle on the 35% either. Trade off is is does not feel as locked in during sequences with the cg that far back.

One note for comparison though, the best (locked in wing during 3D) was the Hangar 9 Cap 232 I've flown (33%). Each aircraft design has strengths, pick your favorite.
