Thanks for the replies guys.
I'm not using Schottky Diodes, I was informed that that was a BIG NO NO with Reversible ESC's. I have three capacitors installed as per the Novak instructions.
I tried moving the ESC and Reciever as far away from each other as possible to no avail.
The timing of the motors is set to 0 degrees, should that be alright?
On another forum a guy said it could be something as simple as replacing my transmitter batteries, so I'll try that tonight.
Thanks again
Dave
