hamid_fireage If you bought your HBK2 in the last 6 months more then likely it came with all digital servos ek2-508 . You more then likely purchased an analog servo. If you only lost one on the cyclic then you can take your tail servo and move it to the cyclic and use the one you bought on the tail. You cannot mix servos on the cyclic as this will lead to serious control issues. Cyclic servos MUST be matched set
Tanks Tommyjoking - your info was realy helpful. I've learned many things from you guys in RCU.
Actually i bought mine 6-7 mounth ago. Refering to its manual they're 0500. I downloaded new king's manual from the official site and in the new manual they're 0508. Thats why i think they are non digital servos. But the first thing which I've learned form the e-sky is; not to rely on their manuals, and you may right.
Anyway i didnt use it I just replaced the stripped gear and still using the repaired servo in the cyclic without any problem. Just wasted around $10 bucks for a stripped gear,LOL.
