i bought 5 corona 939`s from hobbyking/city, 3 died with in 4 flights. its not the corona brand, it`s hobbyking/city.

the corona 919`s are going strong, best servo i have had. i also have the hitec hs-65hb`s, but these are junk compared to the corona ds-919mg`s.

if you are looking for good corona servos ie... 919`s, 929`s or the 939`s, i would recommend buying the from gogo.rc off ebay. hobbyking/city servos are pure junk.

the tarot had developed a shake that would`nt go away.

i took everything off of it and tossed it in the trash.

i have recieved the corona ds939mg`s, i had one fail but believe i have fixed that issue.

i had a washout base binding something fearce when it got close to the head block, the guide pins in the head block were sticking about half way up, i couldn`t even move it by hand.

anyway i installed another 939 and all is well.

these 939`s are slower but have ALOT of torque, so far so good.

i now have a two year old ace-rc 8117 servo going bad, this is now inhanceing my wobble three fold.

i have ordered more corona ds-919mgs to replace the ace-rc`s with, when they arrive i will update on the wobble.

Dear Sir, I've the same problem of tail jerking even adjusted the gyro gain and delay. How can I solve the problem?

[32323222]

@calvinkong mine is a side to side complete frame wobble, most of the time a tail wag is a gain setting issue in your radio.

but if the tail is bobbing up and down, its a headspeed issue.

@NNOOPPAARRAATT

i can tell they are .07sec servos forsure, and they have pretty good torque as well.

i have actually put the 919`s on my metal frame esx Le, installing them on such a heavy heli really woke it up.

i went with the 939`s for the tarot, they have not arrived yet, but i will report my findings on the difference.

to be honest, i have had alot of different brands of servos, so far i like these coronas the best.
