Ok i got some bigger batteries and it still cuts out as i blip the throttle up around half way to full.It's like it goes into some type of freeze mode,even looks like the brakes have been applied.The red light flickers then it goes solid and i have control again..It has to be something to do with programming i'm thinking.Not sure if its the programming of the radio or esc or both.Once again the radio is a Specktrum DX-2 and the the motor/esc combo is the Novak HV 6.5 unit.I have tried my FM radio and the samething is happening..Hope someone has some ideas for me..the battery is a 4600 Ni-mh and the lipo cut off feature on the esc and been turned off
