I bought two versions of the same style landing gear on Amazon.com One was from Hobbypower and the other from Makefire. Neither included instructions and both were difficult for me to figure out how to assemble in a manner that is structurally sound. The screw that is supposed to close the clamp on the leg seems too short and I cannot clamp the leg correctly and have it fit around the bracket to the mounting plate. Does anyone have any experience with these type of legs? I already figured out how to mount the compass so it does not crash.
