I sent an email to Kyosho America; they replied that the x-speed is compatible with the MR03 sport with no modifications needed.

I bought some upgrades that ended up not being compatible after I got them like the FRP T plates, so I want to make sure the next upgrade I get will be compatible.
Looking to upgrade the motor, will the xspeed V motor work on my MR03s ? Do I need to do anything to the board to make the motor work like adding FeTs ?
