I've got a SpinSation.. its a copy, called Bug from Handy Systems, not seen one since i got mine tho.
Don Incolls Wasp is also easy to get hold of in plan version, but come on boys, these are yank toys, how hard can it be? build one side of the fuz, forget the other and a Ice Cream for a wing section.
That Balsa Nova is quite a bit of kit, same guy that gets the IFO's has them, whats the name.... Ansa or sommit
