Well done that Bill. Now that the 10C is available, 10 Bs can be had relatively cheaply. The spar limitation is not an issue for PPL training. Having said that, the aircraft might not be as resistant as a basic spamcan to the sort of rough handling doled out by the average flying school. The French used the 10B to select their military pilots, but PPL studes don't have to take a suitability check (phew!).
