I have also had good luck with the sidewinders... but with that battery/motor combo it might be a *little* much. Your batteries can supply between 90 and 110a and the motor can definitely pull it. You could try a sidewinder but i'd keep an eye on temps. If you fried it I'm pretty sure it'd still be under warranty assuming you didn't make any mods (the crt.5 is "1/10th" scale, right?).

To be safe I'd probably go for a Mamba Max.

I have a Mamba Max and a Sidewinder for sale if you're interested (link in my signature)
