Without speaking for tsands, I thing the general reason to say that it is not really a trainer is that it does not have much dihedral in the wing, it is a taildragger and it is probably not as durable as a typical trainer. That said, it could probably be used as a trainer.
That's about what I was expecting. A plane does not have to be built with huge amounts of dihedral, a nose wheel, and like a brick, to be a good trainer. There are lots of potential trainer planes out there that do not fit the oh so popular .45 engine, trike gear, mega dihedral, and built to withstand nuclear blast trainer profile. This does not mean they are not trainers, it just means they don't fit the mold that beginners are most often steered in. I think it's great to see someone start with something other than the SOS trainers.
