Hitec HS-7955 TG Problem

[2m1986]

Good Morning
This my new model.

C-Arf Mustang modified in Strega Reno Racer with Kolm IL-230cc, about 2 years of work.

On the model I have installed N°5 Hitec HS-7955TG (N°2 on elevators, N°2 on flaps, N°1 rudder), servos are brand new bought from RCToy in Deutschland.

Model is ready for maiden flight, today I made the first run of the engine.
This is the work of one servo of the elevator.

Anyone has suggestion?
What confidence should I have in other servos installed on the model?

Powerplant on the model is:
Multiplex Profi TX 16 Premium Edition N°096/555
Multiplex RX-16 Pro
Jeti Max Bec 2
N°2 Lipo Kokam 4000mA 7,4V

For the short video I made a "fast" powerplant out of the model....

Greetings.

Dear Sir,

i am sorry for that, it seems that the servo is faulty... could you please connect an other one of the same type to the same receiver port? This would be much easier as to take a video. If the other one works well the problem must be the servo, in this case, please contact your dealer or our service department.

Best regards

Good Morning.
The other 4 servos work good without problems.
But also the servo of elevator sometimes work good and sometimes work not good (in the way of the video).

Sincerely what confidence can I have in the other 4 servos seen how it works??
It's a flugmodelle of about 10.000 euro.

I bought the servos from RC Toy in Germany, but the shop seems out of business.

Dear Sir,

please return the servos completely with the original bill to our german service department, we will check them and exchange them if necessary.

Best regards
