Drop chute, cargo door suitable for RC Bushmule - Hobbyking (Avios).

Drop chute,cargo door suitable for a RC Bushmule from Hobbyking (Avios).

The Bushmule has a cargo door built in as standard.
I did not like this design and I have designed a new one
This one fits exactly into the hole from the cargo door.
Only for the servo mount you have to cut out a small piece of foam.

Both flaps are opened and closed by a sophisticated mechanism, with only one servo.
The complete flap without servo weighs only 45g.

The servo mount is suitable for a HK939MG servo (23x12mm).
The servo mount is screwed to the frame with 2x M2 screws.
Two different servo holders are available, depending on the depth of the servo.
So you are flexible for other servo mounts according to your own design.

The frame can be glued into the model or clamped into the shaft.
The big advantage if you only clamp the frame is that it can be dismantled again at any time.
Take the smaller holder for the rear and the larger for the front.
There are 4x 3mm holes in the frame which are not drilled through.
You need to clamp the frame 4x M3 x 25mm screws.
If the frame is glued in, do not drill through the holes!

Clamp in the ejection chute:
Drill these 4 holes carefully
Insert the frame into the fuselage cutout
Drill holes through the foam
Insert Clamp Holder and clamp it with long M3 screws.

Small sheet metal screws are needed to tighten Rudder Mechanics and Rudder Horn.
I used M1,4 x 5mm flange pan-head screw cross recess.

For the flaps I used 2mm GFK (or CFK) rod.
For a good function the flaps must move easily and not jam.

Take care during assembly
The "rudder mechanics-1" must be mounted on the side of the servo on the flap.
Otherwise the flaps will not close

Frame, Flaps, Servo Frame, Clamp Holder with 0,3
Rudder Mechanics and Rudder Horn with 0,2
