What tail servo are you using?  Helps to match them up sometimes.  I like the old piezo hk 401b and many folks have had good luck with the mems ga250.  Both less than $15.  But best to check what servo your using first ;  

And welcome to a lot of fun!  What else are you flying?

Cheers,
Ken

Status: offline 		Ok, Just realized I need servos too. There is (1) Align 6X Micro Servo in the kit. (C614)?? So servo recomendations would be very helpfull too. The Heli DOES have a tail servo mount. Prolly order it all from Hobbyking. It may alse need to be known Im not a 3d pilot yet. So do you still recomend the GA250?  http://www.hobbyking.com/hobbyking/store/__15318__HobbyKing_GA_250_MINI_MEMS_Gyro_.html and if so, What servos should I get? 

Thanks SO very much for your help. I really appreciate it!!

I believe that the GA250 is by far one of the most under-estimated gyro's out there.  I do backwards flight and tail slides with no issues at all.  Set up is so simple, 3 or 4 steps and you are done.  Getting the second half of the menu can be a pain at times.  You have to hold the rudder stick to the side and then flip your gear switch 3x.

When choosing servos, for the tail you need something fast, in the .05-.08 range and in the cyclic the typical servo is .10-.14 range. There are many good servos (Savox, Futaba, Align, Hitec, Hyperion, JR). I'm sure there are many more of those micro servos, but those brands should do you well.

I have some cheap HK servo's on my 500 and i don't like them. They don't center well and I've noticed one moves a little slower than the other. I hardly ever fly it so I'm not replacing them.

BTW, you said you fly giant scale, what kind of servos do you run in them and would you use a HK servo instead?
