I have been using the hot racing adjustable motor mount for about a mount now came across some interesting info on it today. Someone else commented that it's not a very solid mount. So I went to check mine and low and behold mine had play in it when I try moving the motor up and down. I could feel it and see it. Put the stock arrma mount back in. No more play and Feels solid. So in the parts bin the HR mount goes. ?
