Hi All,

I was wondering, with all the outrunners around, how close are they to the same distance from back of mount (rear mounting) to back of spinner backplate (1)? And is there a standard bolt pattern for these rear mounts (3)?

Pletty
Rimfire
Axi(s)
Hacker
Hyperion
Eflight
Cyclone

anymore I'm missing?

After I drew the motor, what about the same for the front (2)?
