One thing to consider with the the 4wd movement, NT's have taken off because to the tin top bodies. You will find that the numbers are attracted to the touring car bodies, because they can relate to it driving on the streets.

12th scale and Pro 10 have died in electric, both classes use the GTP body, (not the only reason they died) 4wd electric touring cars have boomed world wide with body designs of all sorts of cars being available from all different countries.

I know that when we get serious, we prefer the Stratus for a tin top, but what gets the beginner in ???
That Subaru WRX, the Toyota WRC, The Nissan Skyline R34, The Falcon and Holden bodies painted in there Hero's colours.

Going to the GTP bodies for these cars may not be the answer to populate this class. In the end, these guys in NT like the variations in the bodies they run, not stuck running one body design only.

So that's my thoughts and it hurt my head
