Just tight enough to support themselves and not fold when stationary.

I Run Mine like CapeBob says tight enough to hold themselves up when it sits still like on display but as soon as you pick it up or bump it they move.
I used to fly with my Tail blades locked in place so hard no one at IRCHA had the strangth in their hands to move them in the grips.
but the whole Heli Freak crew next to where i camped set me straight. Thanks Guys!!!

Sorry to Hijack the thread, but what tightness should the main rotor blades be?? I just had a little mishap this morning and will now be rebuilding. I had them about the same tention you are talking about for the tail rotors.
I am a complete Newbie, and am just working it out step by step.

Some set the main blades tightness up so when they turn the heli on it's side, the blades won't move in the grips, unless jerked or bounced.
Too tight, and it will get the wobble at part throttle.
You want em lose enough to prevent that, but tight enough so that there is some tension.

Yes, if the blade grips are too tight you will get a head bob at low rpm, but if too loose your are much more likely to get a boom strike if your land firmly with a decaying head RPM vsuch as an autorotation. What happens is that when you hit harder than normal and centrifugal force is diminished because of lower RPM the blades will fold forward and make it very easy to hit the boom. Try it by folding one of your blades 20 or 30 degrees forward and see exactly where the blade will hit your boom.
Blades should be tight enough that when your helicopter is held on its side, it takes a good shake to displace them, but not so tight that you get a head bob at low RPM. If you don't think your blades are tight enough and you're getting head bob you should consider increasing your minimum RPM.
Ohiobowhunter, it's OK to run your tail blades loose. However, if they won't support themselves they may strike the boom on spool up. This usually causes no harm.

Yep,
I just checked mine and I can turn it on the side and shake it pretty good and they stay put.
If it jumps around a lot on spool up, loosen up the blades a little at a time till it's acceptable.
