doesnt that comment make this thread kinda pointless?

I've been impressed with the botbitz escs... use them in diablo without fault on some 500 size whyachi drives, and in 720 on the 700size motors, i blew a motor and the esc was still fine... if a tad warm.

I think a tz85 would run a bosch 750 powered heavyweight.... maybe not for very long though as Ed said- the heat would melt it... the fets are lightly pressed against a heatsink with a bit of compound to transfer heat.. in the big esc's the fets are bolted to a heatsink- much more positive.

However i'd like to see if someone could hack something like the castle ice 200a, capable of up to 300a with current limiting....but then before hacking there £200 isn x 2 = £400 ish... plus all the development time etc... just buy a wotty.
