HS-56HB feather servo could i use one of them for the tail servo on a 450 heli. just trying to put them to use instead of spending more money just let me know thanks

That servo is too slow to work on a tail of a helicopter. And that servo is analog and will not work with most tail gyro's.

IMO, you don't want to skimp on the tail electronics. I chased the tail for a few years before I finally upgraded to a higher end servo and gyro, and it made a huge difference. No longer was I chasing the tail and I could concentrate on just flying. In my case, on my 450 SE V2 I run an Align GP-780 gyro with an Align DS520 tail servo. You should be able to find both of those pretty cheap used. And also, like I mentioned in the live stream, that gyro you have is a piezoelectric gyro that uses a crystal to control the tail and temperature can and will affect it pretty badly.

A good alternative would be a HK GA250 (Assan ga250) gyro and a Turnigy 306g servo (same as KST 313). At Hobbyking the ga250 gyro is only $13 and it has a MEMS sensor, and I believe that Tony has a video here somewhere on how to set it up. The 306g servo is about $25 at HK and is an excellent servo for the price. I have one on my 450 Pro and have no tail problems.

That's basically a clone of the good ol Futaba 9257. I have a very similar 9257 clone on my 450 sev2 and it also works great
