Summary

This is a kit for the mark 4 HD, mark 4 clones, mark 4 from Geprc. The Xt60 is a really tight fit with a 5.1 inch prop but should be fine with a 5inch. The capacitor / xt60 mount is designed for a modified school bus version of the frame common in the AliExpress clones. I'll make one to fit the original mark 4 soon. The skids need to go on before the motors and the internal catch can be wiggled in with a flat head screw driver. If you want to use the the elrs antenna mount on the gps rear end you need the spiked skids or the antenna will hit the ground.
