Okay been flying scale helis for a while now. However I have never given this much thought as to how tight the screws holding the main and tail rotor blades should be. On both my main and tail rotor blades I’ve kept them pretty snug for the most part. However I find myself constantly having to straighten out my tail rotor blades after a few flights. Anybody have any advice on this?

It's very odd that you have to straighten them after a flight. Centrifugal force usually straightens them out when they spin up to flight Rpm n they normally remain straight unless you hit something with them on spooldown or in the event of an accident. Very odd indeed.

I think what’s going on is the fact(on the tail blades) is I have them pretty tight. So when they do move that stay that way. Do you recommend keeping them loose?

I would snug them up "well" At 7K or so on the tail blades they will make there way straight. The mains I set up so if you tilt the heli to its side (full 90deg) they dont move. Tighter is better here as there is less chance of a boom strike.

Grim is right, keep em snug. Too tight n they may not spin fast enough to straighten out under centrifugal force but snug does help against a boom strike in the event of a hard landing.

Yeah Copter Doctor, I think all along I have had my tail rotor blades to tight. I thought that would be best for scale flying. But once they move they seem to get stuck in that position. And I am using scale main and tail rotor blades as well.
