Loss of power and steering

[topperj]

Hi

When running my Associated RC8e I constantly get problems with steering and throttle response after about 6 - 7 minutes of runnning.

It comes and goes.

I'm running the Mtroniks G2 Beast ESC and P2 Beast brushless motor 3000kv; 2x2s Reedy 4900 Lipos.

Any ideas why it's happening.

I've added a fan to the motor to help keep it cool.

Help?
