For you Pro v1 and v2 owners, the new v3 upgrade rocks! I haven't had time to appreciate it until now. Been busy tuning the 7200bx to the DFC head.
Now that I have confidence in the old bird, I've been practicing my backwards inverted flying. SOLID tail! Even with my poor backwards flying I have not had it blow out on me. Of course the 8910a+ is good part of it too. Big big big tail slides and backwards loops even a tad crooked, no problem for the tail.
Just some observations about the upgrade. The plastic links from the yoke to the grips are shorter so you don't have mount the tail hub a couple mm out to get more pitch (right yaw). Just these links would be of benefit to the v1 v2 tail. Also, there are 2 versions of the upgrade,one for the v1 like mine (has the little silver tube at the very back) and the v2 I'm guessing with the machined in "stump" on the gear box half. Zero slop!
