Just finished my Bloody Wonder SPK. Bought the FT linkage stoppers. Problem is the servo arms that came with my Suppo servos are so thick that when I tighten the tiny little nuts on the stoppers, they won't swivel. I backed off the nuts enough so that they move and put a dab of hot glue on the nut to hold it in place. Is this acceptable? That nut coming loose in flight would be a bad thing. Anyone have a similar experience? Any other suggestions?
