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.

BertyvN standard 1:10 size 25spline

BertyvN pls contact the service department for assistance, place item questions in the q&a.

BertyvN unfortunately it will not fit the 144001

BertyvN 2200Mah 3S fits in mine with the battery box to its biggest adjustment. This will smoke the motor and ESC in about 5mins but it fits.

BertyvN The 3100kv is rated up to 15V so technically you can use up to a 4S ESC or battery but the 60A will be to little then, the 3100kv motor has a maximum draw of 80A.

BertyvN Yes it is adjustable.

BertyvN Yes, 3,175mm or you can buy other 48P gear if your motor have different size shaft.
