The CEN site is lacking some info, so I"ll ask here:
What radio comes with the rtr?
Is the only difference between the rtr and fte, aside from the rtr gear, the thicker shock towers and hinge pin braces?
How's the build( fte) ? Is it a pile of slop after or is it a finely crafted piece of machinery? How does it compare ( build quality ) to say a Mugen or Xray?
