Diamond Dust servos
Mine has a OS.46 on it, and JR507's, all I had, I also did a monocoat/ultracoat job on it, in a full throttle straight down dive I pull full elevator at about 20' and I cant get it to explode or anything, looks like it bounced off a wall!! Funny to watch.
So far, about a year flying like this I have had no servo problems, but with a faster motor like yours I probably would step up on servo's but if yours are working...
