Hi everyone.
Finally I went with the 120ax and carbon pipe combo on my fixed venus. After 1 1/2 gals of 10% fuel, I am getting 9.400rpms hot, backed for flight, on a apc 15x11. Ihave to tune the pipe yet. The power is really great, uplines are fast, and i can maintain speed going up, down or just straight.
About the right thrust, I also needed a little more so I made the throttle -> rudder mix with great succes. My aproach is to add right thrust just if a lot of correction is needed, and fine tune with the mix.
By the way, the link that Mprediger posted is for athrottle curve, so you can have a more linear throttle response. Good trick, but doesn&acute;t help with the thrust issue.</p>
