Hey djFrank, have you tried reversing the Rudder channel(4) in the mixer? if it's set to -100, change it to 100, or vice versa. If you find that your Tri uncontrollably spins in either direction, I heard this can be resolved by updating the firmware to version 1.6.

Aside from that, changing the prop direction of one of your motors can help as well in offsetting the torque, as opposed to having all 3 spin in the same direction. Some say you don't need to do this with a tri, as the yaw movement of the servo can counter this but it definitely can't hurt. The way I look at it, if the servo has turn 10 degrees just to counter the torque, that's 10 less degrees of movement you'll have in the yaw.

Check to see that your servo is centered and that your quick connect set screws are REALLY tight on the control rods. Looks like a metal gear servo, so I'm ruling out a stripped gear.

Yes, the -100 is for digital servos and +100 for analog.

I really like the looks of those motors! Any vibration issues?

Glad I could help.

Yeah, I do too. They kind of remind me of the Apollo Saturn V rockets.

Thank you so, so much for the answer here. This may be the answer to someone else's bad day too.
