hobbywing esc in a e-revo

[jsr]

Medusa motors are 4-pole which generate a LOT more torque than a 2-pole so size doesn't really equate one-to-one here. A 50mm or 60mm Medusa will generate as much or more torque as a 9XL (if you choose about the same kV rating). The larger the motor, the more torque you'll get. If your E-Revo fits a 70mm or 80mm, those will work fine and be a bit more efficient at moving all the weight around. Keep in mind tho that most of the E-Savage crowd with trucks ranging from 8lbs to 10+lbs (with batteries) already have too_much_to_handle power and torque from a 50mm 2200kV or 3300kV or a 60mm 2200kV or 3100kV. I'm not sure how much the E-Revo weighs, but it's probably not that much more than an E-Sav with aluminum arms and bits. My TTR ST-1 BL truggy weighs 7lbs no batts, same as my E-Sav.
