And before you flame me, I want to comment that this is another area where the Internet is not like reality. At my field, if you ask someone how they balance their small props, they will look at you like you're from another planet.
OK, having got that out, I am willing to listen and learn. Is there any science that shows how much vibration is caused by the engine itself (just the piston going up and down) vs the amount of vibration caused by the worst case manufactured prop, and what bad things that vibration can do, assuming the receiver is isolated from the vibration?
Well thats why I asked .
TO EARN.
I have to agree that the piston going up and down at 19,000+ rpms and comes to a full stop each way would do more damage then anything else.
I cancelled the balancer because I feel that my home made one is just as good.
Plus I also question the nut being off balance.
I feel that if I need to balance it then i'll replace it.
I think maybe the manufacture of the engine is perhaps thinking of harmonic vibrations and they will run all along the model.
Thanks for the input
