Stephens collective (the "throttle" for helicopters).
This is the top part that houses switches for fuel cutoff, engine start, landing light, and trim.
Lots of hot glue :-)
The part with the yellow gear wheel is turnable to control engine rpm. Its a PVC pipe on a PVC pipe on a metal pipe...
The potentiometer and the gear wheels.
Here you can see the outer PVC pipe (the one thats turnable for engine control) the inner one and the metal pipe inside that one.
Many cockpit builders have found out that the red switch guards as found on real airplanes are very expensive. Stephen made a small version himself. This switch is the fuel cutoff switch on the collective.
