Air-valve for gears or Doors
(no servos)


MHVALVE is a microprocessor based electronic selector valve that operates the gear or Doors of your scale and sport R/C airplanes, the unit will work with all standard radios, and no servo or mechanical valve is required. NO ATV OR PROGRAMMING REQUIRED, just plug in and use it.

The unit comes with 1/8" input and output ports for hi volume of air, also with 1/16" reducer adapters to fit all applications.

    Gold and exclusive Feature:
  • No collapsed gears when the TX & RX are turned on with the TX gear s/w in the UP position. There is no valve movement until the TX is turned on and the gear switch is moved, (toggle the s/w). Example: If the gear is down and the TX gear s/w is up when the TX is turned on, the unit will wait for a down s/w TX signal to be selected. This prevents a collapsed gear.

    Technical specifications:
  • The unit requires power to operate:
  • Operating voltage: 4.8 to 6.5 volt dc (power from receiver)
  • Power Consumption: less 108 ma at 4.8v,
    (10.8 mah / each 6 min. flight)
  • Dimensions: 1 5/16 x 1 3/4 x 3/8 (inches)
  • Temperature of operation: 0 C to 70 C
