Motor Mount Question
 

I am converting a nitro powered Air boat to electric. Can someone tell me what the hole circle or measurement across the mounting holes on the Park E-flite 450 Brushless motor is. I am waiting on the motor and would like to build the mount.

Thanks,
John (Retired Machinist)

It's best to wait for the motor. It comes with an X-mount, and is easy to install.
