I'm building my first scale helicopter and have no idea of what servos I need for the retracts, that will fit the hole. I need 3. Can someone give me some idea?

Thanks

I have seen standard servos used and may be your best bet because retract servos cannot have their end points adjusted and that makes for a hassle adjusting the pushrods. the std servos can be a hassle as well but I think its the lesser of two evils. the holes are purposely made undersize so you can customize them for the servos you choose.

Ok I'll look into them. I looked at the retract servos. I wonder if a mini servo would fit the holes better and do a good job. I'm not to good on modifying yet, lol

What ever servo you get get a fairly high torque rating(nothing crazy needed). It will also help greatly.

A mini servo should do fine and like Coach says, get something with good torque, there are several on the market with metal gears too.
