Roald Hi,Thank you for your input,much appreciated. I suspected a CG so far back would make the plane "twitchy",something I don't need !! I have already set the incidence at + 1 deg and strengthened the u/cart mount.Also I do fly simpler manouvers,I just like good models to fly them with so that I know its my mistake not the model !!!
Thank you again.
