Overheating problems!

[Jez Thain]

Hi all

Suffering major overheating problems to the point where my battery connectors have melted!

I'm running a Tamiya DB01 with an LRP brushless set up in (9.5) and a 4600 NiMH battery. After about 15 mins fairly quick driving it all gets a bit hot, yesterday the connectors melted, any one any clues as to how I can stop this happening. There's a 'slipper' fitted and 26t pinion (too high??)
