figure out how much dammage you have done to it rebuild it if needed and have some fun with it,mine has a OS 61 now,and a pretty thorough overhaul of the fuse,when I stripped the covering I found quite a few glue joints had come loose after all the abuse the old bird had been through,also added a larger tank,and battery so I can fly all day on a charge,at least 6 flights without having to even check the voltage,I have a extra tail wheel assembly so thats a option,I really want to straiten the wings out as well,but thats another project on the list.
