Good deal. According to the info from other bros. here, it includes front and rear universal drive shafts and the slippery clutch. As a rought estimation,
$1220 (RTR) - $110x2 (universal drive shafts front/rear) - $110 (slippery clutch) - $100 (ESC, up to 20T) - $60 (servo) - $120 (AM receiver) - $50 (AM control) = $610. i.e. cheaper than DF03.
