The aileron could be moved vertically upwards. In flight, the ailerons were slightly reflexing. Thom Riddle advised that in the past he ordered a hinge set (body and pin) from Fantasy and it was a simple job to remove and replace it. Rather than go thru the process of trying to find 8 hinge sets for shipping to Thailand, I removed the ailerons and replaced all the hinge pins with Mil Spec hinge pin from Genuine Aircraft Hardware company which was about 13 dollars a 6 foot length. Part number MS20253P3-7200 which is 0.117 in or 2.97 mm. The originals are 3 mm. On the Allegro, the pins ends are flattened to prevent them slipping out. I couldn't see a way of doing this without removing the hinge bodies which I didn't want to do. I drilled each end of the new pin and used a cottar pin to secure it. The old pins showed little wear. The play was more from the loops on the hinge bodies opening up very slightly. I don't know why this should happen on a plane with relatively low hours. I pinched the loops on each body so the pins were a perfect fit in all 8. There is now no play and the ailerons no longer have a slight reflex.
