should work fine. Micro Sidewinders can handle 35a continuous, and this motor is rated for 33a continuous. If you're worried about heat, you can also get a rc18t xps heatsink and slap it right on the micro sidewinder:

Of course the 1/10th sidewinder will run MUCH cooler (since it can handle 70a continuous and has a great heatsink built in). So it all really depends on what you're looking for. My micro sidewinder will reach up to 120*F after a really hard run in a detta st, and the 1/10th sidewinder only gets warm (~100*F) after a hard run in the detta st (with all other things held equal).
