I use a 9303 for collective on a Futura SE.

circa 12 months, no problems. Very powerful, but I've never been sure about its smoothness when I test it on the ground. Still it feels fine in the air, and so far no problems, but make sure you have no possibility of control binding as it will just snap linkages etc.

I learned this the hard way with a poorly set up heli after a rebuild. A friend with a 3D NT uses 3 x futaba 9206 which are similarly strong but seem a bit smoother. They are the recommended servo for the heli so you can bet they've been thoroughly tested by Jan Henesleit.

9303 servo
The 9303 was originally designed as a off road car/buggy steering servo. The resolution of the servo (gearing) is not as smooth as servo's designed for aircraft use such as 9204/9206.

The 9303 is also a brass gear servo which hold very well in heavy load without stripping gears. The 9204/06 uses an alloy gear which is lighter and strong enough for just about anything.

If you already have the 9303, it will work. If you are looking to buy new servo's for a heli and need hi torque, get the 9206, 9252, or 9151.

I use the 9151's which are digital. They are awesome!!!

Thanks for the reply guys,
I have about 10 of them that are new I was going to use on some plank stuff and decided to bail on the project. I currently use 9252's on all of my Heli's and am going to build a couple other ones, a night flying Heli and a camera ship video link.
