My LHS and I finally figured out yesterday that my servo was bad after everything was acting all wonky on my rally. They also said that it's a common problem. So, as with my summit, I went with a hitec as a replace ment. Well, the LHS gave me a servo arm that doesn't fit and I can't get back there for a few days.
I ended up getting the HS-85MG from Hitec and the holes in the arm they gave me are too big and I also can't get it to fit on the servo splines. Also, I would have to cut the last two holes off of it as its too long for the tight space on the rally.
Has anyone added a hitec micro servo? If so, what arm did they end up going with?
Edit: Maybe part number DUBM6675 from servocity?
