New to pattern flying what is a good hitec servo for two metter plane, Thanks Steve

You will find most Pattern pilots use futaba or Jr servos. My experience with Hitec servos is that they don't center well and that is a big problem with precision flying.

I have a set of Hitec's ultra high resolution servos and don't like them for precision flying. Even with the dead band adjusted you can very easily see that the surfaces don't return to the same neutral position.

JR DS821 is a nice entry level (inexpensive) servo for pattern flying.

What Futaba servos would you recommend.

That depends on a couple things..
1. what is your budget
2. are you going 6 volt or high voltage.

If budget is no problem, then look at the brushless servos
My general rule of thumb is 100 ish oz-in for elevator, and 200 ish oz-in for aileron and rudder.

pull down the servo tab and you can look at the spec's and prices.

For Futaba, I would recommend these. They aren't the latest and great brushless, but they are more than adequate for anything we do. The top guys will run the more expensive brushless, but for entry level, these are much more cost effective and work great. These are the servos I used on the Vanquish build thread as well as on my wife's Monolog, and another friend's Monolog. Elevator, S9650, Aileron, S9551, and Rudder, S9155. Great servos but not ultra expensive. For pattern we don't need that much torque. Even on rudder, we dont need a lot. Our rudders aren't that big. For elevators, and ailerons especially, speed and precision are much more important than torque. I know for a few years I flew S9254 tail rotor servos on the elevator on 2m planes, CPLR did the same. Only about 50oz of torque, but it was plenty to run BOTH elevators. Incredible speed and centering though.

I'll be using 6.6V A123, It appears the S9551 may be discontinued. Not on towers or Futaba's website. But the other servos look good. I am not a JR fan, seen to many with loose gear train and I use Hitec titanium gear for my 3D and IMAC but they don't seem to center very well even with a narrow dead band setting. So looking into Futaba. Also, someone mentioned Hyperion servos, although I have no experience with them...

The 9551 is not discontinued, it is backordered. Should be in later this month. ALL Futaba servos will comfortably handle 6.6V. Initially when Futaba only offered 4.8 NiCD packs, they said 4.8 only, but they will comfortably run at 6.6. In fact, in my wife's Monolog, and the Vanquish I put together I ran them at 6.6 V regulated with a tech aero regulator. No problems at all.

Arch I have two futaba s9154 tower says 4.8 volts only and box says 4.8 volts will they run 6.6 volts Thanks

Yes, flew the 9154's on 6.6 volts for a lot of years. All of the 4.8 only servos run fine on 6+ volts. When you get above 7 they start to act weird, but they will comfortably handle 6.6 with no problems. As I said, when those servos came out, Futaba only sold 4.8 packs, so that is what they recommended. Now it is almost hard to find a 4.8 only setup. You wont have any issues running those at higher voltage as long as you dont get closer to 7V.
