Bixler 3 motor mount 7deg offset 25mm

Motor mount for a Bixler 3
Offset 25mm, 7deg. Motor mount holes 19mm-16mm, dia 3.5mm. Centre hole 9mm.
Allowing 0.2mm for printing clearance the screw holes fit perfect.

Most of the Bixler motor mounts are 5deg offset. If you do it by the book it really should be 7deg.
Measure the line from the centre of the motor to the centre of gravity = 200mm. Offset one end of the line 25mm and you get 7deg.
Assuming the Bixler 3 motor angle is correct, this should be the right offset.

I have decided to use a different mount so, i wont know how this one performs, and if the angle is correct.
