The body is a regular RC10 body, not compatible with our RB10 stock chassis (SR10 chassis).

I had hoped for AE to release the RB10 as a kit with threaded shocks and a rear cab body that fits the stock chassis and make it affordable. They kind of listened but not really: the chassis drives the price up like crazy, way beyond the Gforce Genova or Kyosho Dirt Master. No threaded shocks. And long-time RB10 users still don't get a classic style body that fits directly.
