RE: RC Snowmobile Polaris Fusion 900 Build Thread
Here are some close up pic's of the motor and tranny.I am still useing the stock tranny and gears.They are still holding up fine and i have run it about ten times.
You can see i drilled a couple holes for cooling on the motor mount side of the tranny.I also cut the round area on the motor side of the tranny to allow a 550 motor to fit and to provide enough room to adjust the gear mesh.I also elongated one of the motor mount holes to be able to swing the motor,also to provide propper gear mesh.
