I'm wondering how tight to tighten my blade grips on a Raptor 50? Is there some kind of rule of thumb? I had a blade fold slightly and loose tracking a few times on my Raptor 30 (both wood and carbon). To check the 30 I would tip it towards me 90 degrees resting on the edge of a skid and support it holding the blades (about an inch from the end). If a blade floded I would tighten it. Using this method I feel I may over tighten the 50, especially when I get oil in the grips.

You should be able to put your heli on its side, while holding in your hands, and give it a light shake, up and down, and the blades should almost not move. Your always better to have them tighter then looser.

Steff is right, that has been the standard answer for years but myself I go pretty snug, but not 600LB Gorilla tight. If your blades are flopping back and forth they are too lose, they should pretty much stay where you put them but still fold back into your blade holder without feeling like your forcing them. At the RPM's we run our heads at nowadays, you can trust the blade will have enough lead/lag even if they feel very stiff on the ground.

The guys doing blade stop autos just about spot weld the blades in place before doing it because if the blades rabbit ear on you, your done. If you have to bail and power up again your going to take out the boom if the blades are loose. Bad all round, snug 'em down good.

One last point is that if your blades are loose, if you need to tune the engine or something after flying and you go out and stick your hand on the headbutton, it's a real pain and you look dumb if the moment you apply the slightest pressure your blades fold around and tip the heli over. I really don't know much about that though.....

Keep em snug, it's like keeping your stick on the ice.

One brand of heli is no different than another in this respect.

What steffgiguere said.... I just learned this very technique from a Sponsored Pilot I get to fly with.

He also showed me a similar technique for belt tension. Loosen the boom, and hold the heli in the air by the tail and giver her a little shake. Then tighten down the frame.

Hey, neat idea on the belt, never thought to try that, sounds like a good idea. Typically though, the boom is pretty snug in the blocks or frames (depending on the heli) and I'm not sure it would drop into place properly, I'll give it try next time I'm putting on a boom.

Thanks for the tip.

Thanks for the replys. I'll keep with the method I described above. I was just worried that I may be over tightening them and could weaken the plastic grips. Guess it may be best to clean the oil out of the grips from time to time

Steff, I'll give your method a try as well. I think mine is about the same. In mine I support the heli by holding the blade near the end. If either blade folds I tighten it. About the same just not sure which method would require a tighter grip.

They need to be able to lead and lag a bit so if they are too tight you get vibration.

If they are too loose then you risk chopping off your tail boom if the head speed gets too low like in an auto.
