Very simply get a thin punch or nailset, tap lightly on the pins. They will come partially out the other side. Then pull them out with any decent plier. A little of WD or blaster makes it quicker. Then clean with brake cleaner and reset. Saabs forever. P.S. Is there a wing accessory package so ours too will fly? VVVVVVVVVVrooooooooooooooooommmmmm!
