Would this motor fit straight into a arrma infraction?
Asked by Brian on 8th January 2020
Hmm, diameter on the stock motor is around 41mm, diameter on this is 49mm so it is a good chunk larger. I've not tried it - but would suggest this will not have enough clearance against the chassis to fit, so will not fit without modifications.

Asked by Stuart on 2nd March 2022
No, this is for the bigger 8s Kraton, you would need something arround 2200Kv like SPMXSM2700

Hello I have a pro boat sonic wake v2 would this motor work in my boat I’ve got a 160amp esc want a power full motor to run 8s LiPo please can you get back to me carl
Asked by Carl on 5th October 2023
If you can physically get it mounted that will work on 8s but it is not water cooled so you may have problems finding a water jacket to fit.
