My G&P M249 said to use it on Nimh and DO NOT USE OVER 7.4v
It was rubbish, really dissapointing. It's weird, boxmag is wired to Large tamiya on a battery and the boxmag is wired to deans into the RIF.
Chopped off the large Tamiya, soldered on a Deans, chucked on a 4000Mah LiPo 7.4v and it's in GOD MODE now.
Huge improvement.
I'd of done it straight away but as it recommended the Nimh I tried as told. Utter twaddle. Go LiPo....
