## Description

desertcart.com: HobbyStar 3660 4-Pole Waterproof Brushless Sensorless Motor for RC Car, Truck 3300KV, 4T : Toys & Games

Review: Excellent 3300Kv motor, worked great on a RC10GTe conversion - I did a LOT of research into what brushless motor to use for my RC10GTe 1/10 truck. This motor seemed to be the perfect combination: 3660 size, 3300Kv rating, compatible with 3s batteries, and a 3.175 mm output shaft. I paired this motor with a 100A ESC, and 16T pinion/66T spur gearing, and it ABSOLUTELY RIPS. The rear of the truck squats under full acceleration, something the nitro motor NEVER did. I previously bought ESC/motor combos for this truck and was burned by junk quality and inoperative parts. NOT this motor!! I do not have any input on longevity or durability, but initial impressions are great! No complaints thus far.
Review: have it in a arma granite runs good on 2s and flies on 3s - great motor for 1/10 scale off road truck
