Electric Landing Gear & Door System
MHGDC is a
device capable to handle the gears and doors cycles, time and sequence
for scale and sport R/C planes, its designed to work with all standard
servos and also the new (MHV) computerized pressure GEAR AND DOOR
only consumes 30 ma and it's a small package. It uses the gear ATV
to set the travel of the gear and doors servos one time, the unit
will memorize the data that way gear up and down is only required
to initiate the sequence.
Every time you
turn on the receiver with the TX on, the unit will initiate the
sequence accordingly with the gear selector s/w position and if
during the transition the gear s/w is changed, the unit first finishes
the cycle then initiates the new command , that way it prevents
door and gear miss sequence that some times ends with damaging results.
If you turn
on the RX only, the unit will stay in the last position that you
previously had set, it means no output to the servos or (MHV) until
you turn on the TX.
Diaz found a very nice and interesting feature about the MHGDC,
after programming the ATV for Gear & Doors, the gear channel now is
almost a free channel, that can be shared with the gyro gain selector
with a " Y " extension in the gear channel. After the programming is
done, you set the appropriate Gyro gains without any effect in the
gear positions -- guess what, one more channel.
