BertyvN Dont mind Cody's answer, think he had a few too many drinks when he answered Crawlers tend to start up smoother with a sensored ESC and motor combo, this motor is sensorless but will work with a AM32 128kb or BLheli Dshot1200 software ESC.

BertyvN I have V1 and balances slow but fine

BertyvN My motor arrived with a 3.17mm or eigth inch shaft

BertyvN yes, but very strong for buggy use.

BertyvN Yes, but gear it slow. This motor does not have a internal fan like other sealed can 550 motors. Set the timing to 0° as it comes with 10° timing from factory. Motor is very smooth but esc has limited settings like hobbywing 1060, also not waterproof as claimed.

BertyvN yes Standard 1:10 scale 25mm apart.

BertyvN It doesnt matter what length it is, it falls in the 3660 bracket, much more power than a 3650. Mine last 26mths with lot of offroad abuse including beach, mud wet grass and high speed pulls from a dig. Ran it on 3S 5Ah 45C batt with 120A 1:8 ESC.

BertyvN i have had mine submerged plenty of times and have had no problems. But do open the servo to double check all O-rings and silicon grease all joints as a precaution.
