T4 Quad Arm for CF2822 Motors (22 mm hole spacing)

New design for the arm for using the Emax CF2822 1200Kv motors with 22mm hole spacing. The motors mount on the outside of the cup with cable ties or screws.
I use independent 30A ESC so I made a recess on the arm for it so it would be on the prop wash for cooling. The ESC do not get very hot but as a EE I know that cooling power electronics is the key for long life.
I will include the Alibre file as well as the .igs export for those wanting to make changes to fit their motors.
