i have the cheaper EPP black type 12x45 props from jDrones,
as i mounted one of the on the motor, it's clear it needed to be balanced.
as a temporary method i put electrical tape on top of one of the prop's sides,
it did the job and i could reduce the vibrations.
but how about a long term solution ?
i've read about sanding down the prop (off the surface i guess) to take material off on the wanted side.
would you do that ? what is the preferred method ?
