Front landing gear door
Cut out the central part of the lower engine cowling where the front landing gear door will be positioned.
Above: the front landing gear door instalLED with a Spektrum A6030 servo and 2 hinges.
The front door must be glued to the lower engine cowling, with 30 to 40 minutes epoxy glue, using 2 nylon
hinges (we recommend DUBRO DUB 257) or 2 compartment door hinges. We recommend ROBART (ROBQ 350).
Remember to check the correct alignment of the door in the closed position to permanently glue.
The opening and closing mechanism of the front landing gear door can be done with 1 servo (with metal
gears and with 20 Kg/cm or more of torque) or with a pneumatic piston. It is necessary to install a short horn
for the linkage or use the hinge itself.
For front landing gear door opening and closing sequencing, a landing gear door sequencer or, if available,
mixing via radio channels is required. The sequencing schedule should be like the routine below:
1.
Landing gear and doors totally closed.
2.
Front landing gear door opening.
3.
3 landing gears extension (and the 2 external main landing gears doors mechanically).
4.
3 landing gears retraction (and the 2 external main landing gears doors mechanically).
5.
Front landing gear door closing.
