I'm building a QQ YAK 54 toc version and was using 5995 on the rudder but it is pretty scary that really no one has come up with a solution or a fix for these servo's,, so I will cancel my order also, until I here what is going on with these servo's. I really like hitec servo's and have bought atleast 20 in the past 2-1/2 years. I haven't had any trouble with the servo's ,but I can't afford to do thier testing on my plane.
