The worlds first production high wing Cessna main gear retracts. For 8 to 12 lb aircraft. Retracts actuate by direct servo drive. A second servo is used for positive up and down lock. The locking pin prevents landing loads from working against the actuation servo and reduce buzzing.
Use your radio or a gear door sequencer to actuate the locking pin servo. Left and right actuation servos run in opposite directions. Reversing can be handled with separate channels, sequencer, or programmable servos. Locking pin servos may be driven by separate channels or a reversing Y. You must be capable of programming these procedures on your own or use a gear door sequencing device. We will be unable to provide programming steps simply because we do not own every possible radio.
Order of operations is exactly like gear door sequencing. 1. Pull locking pin. 2. Short delay then deploy gear (Or retract gear) 3. Short delay then engage locking pin.
Locking pin servo can be an HS-55 or HS-65HB. Unit is designed to use either servo. A spacer is provided for the 55.
Actuation servo needs to have 180 degree capability. We have used the HS-5645MG. Available below.
A Hitec servo programmer is useful to set servo speeds and end points. These settings may be available in your transmitter or in a sequencing device.
