I am currently having some problems with my esc. I run Spektrum DX3.0 and have this same problem with all 3 of my Futaba (2 x MC330R, 1 x MC230R).

When i ease on the trottle, it powers up fine to 100%. But when i dump to full power from the neutral position, i think the esc is activating its overcurrent protection.

If i turn the forward throttle EPA down to 90%, then its fine and i can throttle my heart out. But then i lose 10% of my speed as well.

Any help would save me $300 worth of electronics. Please help...
