Gert, not to worry, if you built it as per instructions and plans, it will take ANYTHING you can throw at it. Ask those that have seen me fly mine-CRAZY snaps. I questioned the ability of the airframe to handle such violent manuevers when I first began, but it has perservered.
BTW, Kevin is the one with the twin, although I do not know if it will be ready for FJ. My surprise will be sporting a "new look"

(hopefully).
