MD922 :

1. Adopt metal gear, the gear accuracy is higher, Servo's output deviation is very small.
2. Use Japanese raw material to produce outer shell.
3. High accuracy drive plank, respond speed is less than 4 uses.
4. High sensitivity and speed, make most rapid and accurate response to control signal
5. Henge MD922 digital servo are especially designed for dynamoelectric helicopters to control the direction, and compatible with many gyroscopes such as Futaba 401, 601; MD922 is suitable to be used in 450 dynamoelectric helicopters to control the direction and high speed gliders.

MD933:
1.Use metal gears, especially use steel material in output gear, which has better intensity , abrasion resistance and accuracy, makes sure servo's output deviation very small after long time running.
2. Use high quality motors as FUTABA's, makes sure the servo's life longer, and tests prove it can continually run in high speed for 50 hours.
3.Use Japanese raw material to produce outer shell, which is more sturdy and durable and can bear 120 temperature.
4. Rapid response control, better acceleration.
5. Very nice consistency, center error less than ±0.5 degree, angle ±40 degree, biggest ±60 degree, error less than ±0.5 degree.
6. Have overload current protection function, even if the output gear is blocked, motor and electronics component will not be damaged.
7.Suitable to be used in 450 dynamoelectric helicopters to control the inclined dishes and in fixed wing airplanes
