Caliber 30 model helicopter radio control installation for my machine
A mechanically mixed radio control installation was used on this helicopter.
Above pictures show the rotor head of the model helicopter and the radio control installation for the cyclic and collective controls.
The helicopter can be setup with two alternative mixing arrangements, a mechanical sliding servo tray which is the system I'm using or a completely electronic mixing system.
The mechanical mixing system uses four ballraces on the servo tray and works very well. I tried the electronic mixing setup at first but had some trouble due to the fact I've misplaced the computer radio's manual. Must be somewhere under all this junk :-)
When I finally dig the manual out I will try again.

The tail rotor servo on this helicopter is mounted directly onto the tail boom tube. This gives a shorter and more positive control linkage arrangement than more conventional designs but care should be taken that the mount cannot move up and down the boom.

The tail boom is supported by twin aluminium tube rods as shown above. Tail fin and horizontal stabiliser are made from a plastic similar to polypropylene (could be polypropylene). Skids are aluminium mounted into plastic arms, these are quite narrow but the model is quite stable on the ground when taking off and landing.
The helicopter's main rotor blades are of symetrical section. These are made from wood (looks like spruce and balsa) and pre-covered in a transparent plastic material. Fly-bar paddles are hollow plastic components.
The tank is quite a large rectangular unit, this is pre-assembled with a standard clunk arrangement. To fill you need to pull off the carb feed pipe and pump the fuel down the pickup tube into the tank, I would prefer a separate dedicated filler.
