Updated V2 chatting to itself

[ICUBoy]

Hi all.
Thanks to the input from everyone on these boards I lashed out and put together a new Emaxx, MedUSA 60-2000, MMM (V2 with update to 1.20) and 5S2P A123s.
Wow this thing really goes! Flips on the lid with a gently throttle caress.
BUT off-throttle the motor just sits there cheeping and chipping away like a budgie. I am using the stock radio- any idea why the motor wants to chat so much?
I must say I don't mind- it's still BIG fun.
Thanks again and enjoy!!
