While using a 10X Illuminate Magnifier to inspect my MP I found the right rear axis arm hinge cracked. There was no indication of an issue in flight, I was just doing normal post/pre-flight checks. I purchased a new hinge assembly from Amazon at quite a reasonable price and facilitated the repair myself. It required the partial disassembly of the MP, removing the top and the entire right rear arm assembly which included de-soldering the three wire connections. Was a simple repair and was completed and reassembled within a couple hours.
