Default Main rotor bolt torque?

Anyone have any advice for how much torque to put on the bolts that hold the main rotors on? How about the tail blades? Should they be able to freely and easily swing around or should it take a little effort to move them?

I keep mine loose enough that I can move them with my hand-but snug enough that they stay where I put them

Thats pretty much correct. If you hold the heli on its side the blades shouldn't flop but if you bump them they should move. A little tighter for learning/practicing autos.

Too loose and they can lag too much and chop off the boom if the head speed drops, too tight and they can't lead and lag and you get vibration.

Thanks for the info guys! If it wasn't for this site I'd prolly have a $2000 pile of parts right now instead of a heli.
