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
Carl / 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.

Will this fit in typhon tlr ? I have spektrum 160amp esc to run it with, if not can you recommend one that will . Kind regards Stuart
Stuart / 2nd March 2022

No, this is for the bigger 8s Kraton, you would need something arround 2200Kv like SPMXSM2700

Si @ Wheelspin Models
Hi, would this fit in my RC8B3.2e?
Emma Giles / 22nd February 2021

I suspect it'll be too large sorry

Ben @ Wheelspin Models
Hi there do you have a mounting bracket for me to fit this into my kyosho scorpion xxl . The one already in there is just a little small Kind regards Annette
Annette Senior / 13th August 2020

Afraid I don't know to one sorry

Ben @ Wheelspin Models
Would this motor fit straight into a arrma infraction?
Brian / 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.
