I've had two of these. I had the 46AX inverted in it and never had any issues at all with the setup. The first one I had you had to put some crazy bends into the pushrods at the elevator and rudder to get them to mate to the control horns, possibly a cause for flutter that some have talked about but I never experienced it. The second one the pushrods lined right up and made for a linear install. I did add a couple 1/8" washers to the back of the top engine mount, one per side and it seemed to line it up better for my preference. Hope this helps, I have been thinking of getting another some day, but right now space is at a premium.
