I would like to give my 50 cents worth to the subject. Hope you don’t mind Sean.
I found with all my Mig’s if there is too much elevator deflection applied all the Mig’s tend to snap. Especially if the CG is set a little to far back and also in low wind conditions.
Mike check your elevators deflection, it might solve your problem. Let us know how you are getting on.
