Product information

Super strong standard digital servo for the most demanding applications with metal gears to the output shaft is supported in two ball bearings. The increased voltage (up to 7.4 V, 2S Li-Poly / Li-Fe) is very simple to implement on-board electronics with 2.4GHz receiver Optima series with the power of dvoučlánku Li-poly or Li-Fe without the need for additional stabilizers or regulators . Ideal for model aircraft of all kinds (for up to 30-40 cc combustion engine), electric helicopters helicopters size 600-700 or 30-90 with a combustion engine, cars and boats. Comes with rugged plastic levers filled with glass fibers.

Hacker digital servos Hitec HFP-20, HPP-21 or HPP-21 Plus can be programmed:

     reset to factory defaults
     width of deadband
     Direction of rotation
     rotational Speed
     neutral
     The travel
     on or off, fail-safe
     emergency settings deflection fail-safe
     overload protection (power limitation 0-50% overload)
