nice! i wanted a neu for my, i mean my daughters 18T but castle had the 4200 on sale for $20 a while back. 3racing chassis, exo slipper and shaft, sidewinder micro, zippy 1600 2s and a digital mg servo. made my own draglink to get rid of slop (1.6mm CF). and lets not forget the ginormous s3000. it drives MUCH better but needs some foams.
