What is the recommended timeframe for a gearbox coupling replacement on my HF-110?
Are you referencing the torsion damper or the actual coupling itself. The torsion damper every 5 years. The other should never need to be changed unless it hasn't done the SB's
I'm referring to the 3 rubber couplings that go to the gearbox
Those are every 5 years :)
Looks great John, The cool thing is you have one of the very first Vikings ever made, the HF-110 is like owning a piece of history. Very happy everything is working as intended. Like what matte paint does, gives things a more rugged/utility look.
Do think increasing the pitch on the Warp Drive prop would make any difference?
Takeoff RPM is 5,500
