I am installing a Spektrum A8010T in my Top Flight Cessna 182, using Hitec 645 MG servos. In addition, I have been getting my servo leads from either EBay or Amazon depending on the price. It seems that every lead, or servo plug needs to be sanded, or filed to narrow it, or corners rounded to fit the receiver. I have had trouble with every single one, but the bind plug. Is this intentional? I can't imagine that Spektrum specs are the problem, but you never know. Ant info, or tips in connecting the leads is welcome.
