Adjustable Height Landing Feet for FPV Drones
Description
This print solves a payload clearance issue for pilots. Pictured is a build running the Lumenier QAV-R 5" frame. The mounts are made for 16x16 M3 pattern. Each piece gets a 5mm threaded insert and the base gets a 5x20mm threaded rod. I used threadlocker on the base so that the threaded rod is set in there real nice.
Warnings:
1. The feet will absolutely back off and fall out of the sky with motor vibrations. Recommend using some kind of thread tape, rubber washer/seal, or something else to keep them in place. Simply hand tightening down the feet securing can work if your print has enough friction. Just beware that this may happen.
2. The taller landing feet introduce some torque on the motor arms so take care with landing. Any lateral forces on those feet may twist or break your drone arms.
I printed this is PA6-CF with 30% infil and .12 layer height.
