sorry dude but you're doing something wrong then. if you sand them to balance them then you have to seal them up again. that's why i don't sand them to get them balanced, i use blasts of spray paint for weight and that gets them perfect.
i sometimes check them for balance after they've been on there a while and don't generally find much wrong with them unless they've been dinged.
carbon fiber is good too but there's nothing wrong with wood if it's done right.
sorry dude, you're wrongI'll bet you no matter how you seal them wood props will not stand up to mid summer humidity. Vib meter. I bet at least a 10% increase in vibes during July/August in Ohio compared to Carbon or composite folding props. BET?
i need to ask the supplier if they are interested in selling more of the clamps. the second time i ordered a bunch of them i got a call from their engineering director asking what i was using them for! they're not a heli supply place so they we curious why i was buying them thirty or forty at a time.
