OK guys, thank you for the info, i'll order a Quark 125 or a Barracuda, but probably more a Quark, for the Mike's service

And cut the casing, and put some heatsink on it., and void the warrenty
But somes guys tell me that the Barracuda is great in a monster truck, and work great with neu motor too. No heatsink on it and seem to hold well.
