Andrew, many thanks for your speedy reply. Yes, the previous owner fitted the wing fences. He also tried the tail fences but felt they contributed little so removed them. The aircraft certainly seems to spin upright and inverted in a normal fashion. Hope to get out and fly again early next week. Have added a slight amount of up thrust to counter the slight dive when full power is selected during level flight. Will see if that affects the up line which looked pretty good on the first outing. I had the same snap set up as on the Agenda forgetting that the Element has bigger ailerons so the snap was extremely fast! Have reduced the aileron throws and will see how that feels. I'll post once I've flown again.
Peter
