Thought I'd ask for comments before doing something stupid and
irreparable
to our propeller.
...
It's a homebuilt, so I'm deep into "experimental" mode on this one.
Anyone
want to warn me about how I might kill myself doing this? Has anyone done
this before?
Sure, I'd be happy to warn you.
Has anyone killed themselves after cutting down a prop?
Yup.
Cut down props were popular on the early T-18's - at least until the first
few fatal accidents. When the blade broke due to resonance / fatigue the
engine would part company with the aircraft and the result was typically a
dead pilot / passenger.
Changing the length of the prop changes the resonant frequencies with
unpredictable results.
