Retract
This is an over the top retract. Metal and not plastic. Very high quality and I would highly recommend it.

Then I installed the struts and repeated the swing test again. They retract perfectly, but one gear would not extend. I fussed w it for a bit and discovered that for what ever reason, by just tightening the grub hold screw to secure the 5mm shaft in place the gear motor would “amp out” (as designed by the way) and not extend. BUT, when I loosened the grub, the motor worked fine. Hmmm?? I swapped gear legs w another strut assembly and the same anomaly occurred. I messed w everything I could think of, including a call to Motion. No real help that I hadn’t already done. (Thx Martin). THEN, I decided to rotate the strut shaft 180 from the factory assembly which was basically turning the knee action spring around and that also placed the strut grub screws on opposite sides and AWAY from the gear motor. Reinstalled the strut in the gear motor and bench tested it again…this time it worked fine. 🤔. I have since swung the gear about 20-30 times without a failure. But I guess I’ll really know if I solved the problem when I maiden this week or pile this junk in from a gear up landing. We shall see 😏

Test flew it today and it is like butter compared to the original and far stronger. I also noticed the circuit board has been sealed perfectly against water and wet grass intrusion which was a real bonus and gives great piece of mind.
