I think you raise a very good point here.

However, the incorrect incidence of the main wing can be traced back to the manufacturer since they devised the construction process requiring that the builder drill the holes for the main wing in both the wing and the fuse.

I think this incorrect incidence could very well be the main problem causing these planes to fly tail heavy.

I will not buy another CMP product and I will do what I can to stop everyone I know from buying their crap also.

Good luck with your Zero.
