The Corona DS843MG is closely based on (and may acually be) the formidable Hyperion DS09-AMD servo. A plasic gear version of this servo is also sold as the Airtronics 94802. With very little free play, excellent torque, and a good speed, this is an excellent glider and small electric model servo.

At only 9 mm thick this superb wing-servo can easily fit in very thin wings. With 2.4 torque and and lightening 0.10s/60° speed it is excellent for DLG flaperons, ailerons, elevator and rudder on many high performance gliders, DLGs, electric gliders, and sport slopers.

Please note the HK specifications are incorrect. Ours are accurate.

Superb little Servos

I bought these lovely little servos for my new X-RES. Resolution and speed looks good running on a 2S lipo. I'm very happy with my purchase and of course the top notch service from Neil at Hyperflight

 Review by:

Bought these servos to fit in a thin wing and because of reasonable torque for their size and my budget. First time buying coronas. Have not been disappointed so far and would buy again. Service from hyperflight as ever outstanding.

Great little servos

These servos are great. Slim, light, powerful and with metal gears. What more could you ask?
They operate beautifully, I have them buried in the tail of a "Watts Up" eSoaring model, controlling rudder and elevator.
