lots of choices the from hobby king the 922's work well on cyclic, fast digital metal gear.... Personally I prefer Hitec 5065 mg's...
if you want the cheapest that will work well (wont handle a crash though) hxt900 (also available from HK..
search for gotek 9257 again at hobbyking for a tail servo for that bird....

first CP heli?

My cheapo setup is 3 HXT900's for Cyclic and an HS-81 on the tail. Pretty quick servos for sport flying... no match for 3D.

I'm using Hextronik MG-14 in my 450Pros. Not expensive but center well unlike the HXT900 which I installed in a $9.99 HK450 frame.

It's a good cheap .11 second (on 4.8v) servo. It's just fine for sport flying and light aerobatics.

im using hxt900 on cyclic in my hk450, also i found with mine it didnt need lock tight at all! all the screws were already lock tighted, and i bought mine a few weeks ago, the hxt900 are good strog smooth enough servos, and on tail i have a emax es9257 that i won in a competion, and it workes great!! 0.05 seconds at 6v, more then i need for basic sport fling, but will be excellent for 3D.
