Son flew his Flair Extra 300S 140 last weekend and one of the ailerons decided tp part company over a massive pea field! Never found it despite spending 5 hours looking! OK so I made a replacement out of solid balsa, same size and same weight. Decided to replace the hinges supplied with 1/4 scale size hinges complete with split pins. Because we are using these hinges instead of the biscuit hinges supplied, there is a small gap between the wings and the ailerons due to these hinges. Someone at the field today reckoned that this may cause a problem if the ailerons weren't right next to the wing (i.e. no gap at all). Plane flies OK but is he correct or not? Would a small gap make a big difference?
TIA
