It is a powerful little beast Joe, Pulls my 8Lb plane out of sight in a few seconds, hovers at 1/4-3/8 throttle. I would reccomend it to anyone
for it's ease of use and tuning, not to mention OS reliabilty.

I have seen the 120AX turn a APC 17x10 Narrow, with a tuned pipe on a Zen 90 pattern plane. I use a 16x8 APC when I fly my Yak precision
and a 17X6 for 3D. the plane flies a bit faster with the 16x8 which makes it look a little less twitchy to the judges.
