HEQ g-port gimbal retract unit

grabcad

Retract unit designed for belly of drone (plane/multicopter). Total movement is about 48mm. Steel rods are 3mm x 80mm and one 3mm pin 13 long. Brass sleeves 4mmOD to fit on rods. It may work ok with PTFE tube or no bearing at all with smaller holes. Carbon torque tube is 8mm x 75mm, make sure both arm ends are exactly parallel and use CA glue. Bearings are 3x7x3. This is sized for servo -HS5425. (EDIT also there is another bracket for the Savox SH-0256+ high torque micro servo) . If you use a different one the opposite pin needs to align exactly with the servo axis. Bearings are screwed in with short m3 cap head bolts. I used PC to print this but probably anything will do. To attach gimbal I suggest replacing the carbon vibe plate with the printed one here and use m6 bolt after tapping the plate m6. The belly foam in my plane is 25mm deep. You may need to adjust for yours.
