I have been using these for years. With most of my fleet of planes, I use not the cheapest but maybe the next one up on most of the plane except for the elevator. Too me, need a good one on the elevator.

So with helis, I plan on sticking with Hitec but unsure of what is what as i am not too familiar with the mini's. Not going to get the rock bottom but what are decent servos. I was looking at the HS-81mg for everything but the Tailrotor and probably a decent fast one for that. Any thoughts on this would be nice. Thanks

hs65hb ( carbonoite gears ) or hs65mg ( metal gears ) for the swash and futaba 9650 digital for the tail seems to be the hot ticket.
you don't have to go digital on the tail but if you can afford it, it sounds like it will work alot better with a hh gyro.

Anything better than the hs55's and you are good, the hs56's are ok but like rest said, the 65's are probably the most popular.

Which heli are you considering? That will make a difference in servo suggestions.
