panayiotis_1984 it's 3660 I just measured it .

panayiotis_1984 it works with 2s and 3s lipo. The less kv the more powerful is the motor and less top speed, the higher kv the less power has the motor but is faster in top speed. Generally a 3300 kv motor or smaller kv they are powerful for 1.10 or 1.12 rc's. Even a 4000 kv motor can take 3s lipo when use it in 1.10 rc cars. Over 4.000 kv the motor start to become less powerful. if you want higher top speeds choose higher kv motor's and don't put very big pinion gears or else you push the motor to do work that can do easily. If you want to do high speed passes put bigger pinion gear and big battery but don't drive hard in off road.

panayiotis_1984 thanks man appreciate it. i was curious to because is 1.12 scale it came to my mind the cr12.
