Simple universal motor mount
The simplest way to mount any can shaped motor on
your Mugi is with heavy duty cable ties. This solution
is extremely strong, quick and easy. The motor sits
at the rear of the aircraft in the middle portion
of the M shaped silencer cutout. The motor must act
in pusher mode.
Making holes for the cable ties
The motor on the Evo is attached by two heavy duty
cable ties. 4mm wide cable ties are perfect for this
application (these are included in the Mugi Evo kit).
Place the motor in the required position central to
the aircraft and as far forward as you can get it
without the prop interfering with the trailing edge.
In practice it may be necessary to cut the tail point
off the silence cutout for extra clearance.
For high torque motors - e.g. brushless motors, a small piece of self adhesive hook and loop fastener between the motor and the aircraft will prevent the motor from rotating in its mount.
With the motor in place, take a pen and mark four dots
either side of the motor, the motor's width apart.
Two dots should be made as far forward on the motor
as possible while still allowing the cable tie to
grip the case of the motor. The other two marks should
be made near the trailing edge at the rear of the
motor. You can then insert the cable ties through
the wing as shown in the first diagram
Tightening the cable ties
Place the motor in position and then tighten the cable
ties as follows:
The front cable tie should be pulled as tight
as possible - this will pull the nose of
the motor into the wing and create the desired thrustline.
The rear cable tie should be tightened to provide
a light grip on the motor - in practice this
cable tie merely keeps the alignment of the motor
and prevents it from yawing.
