Hi Guys, have 3 blade prop problem. 1 blade is extra heavy. unable to get blade 1, 2, 3 marked as heavy prop blade ends up pointing straight down. Have drilled several holes in it sanded the crap out of it and its still points straight down. I have ordered Master airscrew replacement as factory balanced. how would you advise sorting this problem

Add tape to the light blade(s). Something like Sellotape crystal clear which is UV resistant.

I use superglue on the rear face, keep adding layers until balanced

I use the wife's clear nail lacquer, dries real quick. Lay it on with brush either lightly or heavy. In the end she gave me the little bottle. :lol:

And how do you balance a prop Phil?

This might seem daft, but is the mounting hole central? Manufacturing errors do happen, and quality inspectors do sometimes "let one through". I suggest this as I have a brushless motor that vibrates, I thought the shaft was bent and replaced it, there was no reduction in the vibration. Eventually and by accident, I found that the mounting hole for the prop shaft had not been drilled correctly and is at a slight angle, this throws the motor completely off balance. Unfortunately the motor was a Giant Shark purchase, just before they closed down so no chance of a replacement.

Don - Don't know how you balance props, but a DuBro "Prop Balancer " just appeared on the BMFA website - Ad ref 104750.
He's also selling a servo lead crimping set - ad ref 104749.
Regards
Colin.
p.s - Cannot help with nail manicure aids.
