electronic throttle failure

ATV on the Tx not set to 100% on the forward end??

Two possibilities - first, you're hitting the ESC's current limit, if it has one, and it's cutting power to protect itself. Second - and probably more likely - as you move the throttle forward, the current increases and the voltage drops, so you may be hitting the low-voltage cutoff. I had one ESC doing that when I was using a 2 cell pack and the ESC was expecting a 3 cell pack, so it didn't take much of a voltage drop to go below the 3 cell LVC.

What size pack, what motor, what ESC?

Ted shuffled out of his cave and grunted these great (and sometimes not so great) words of knowledge:

If the ATV is set to 100%, it sounds like the motor is pulling more amps than the controller can handle.

If this is what is happening, the ESC is shutting down to protect itself from burnout.

Try a higher capacity ESC and see whether your problem continues. I think your problem will disappear with a higher rated ESC.

...Than the PACK can handle. Its hitting LVC.

Probably a Kokam pack. Real capability=66% of claimed ability.

Which would pull more amps? Higher RPM, less pitch or lower RPM, more pitch on the prop?

I am running a JEIT PHASOR 15/3 BRUSHLESS MOTOR and a JETI ADVANCE PLUS 30 AMP CONTROLLER
