Mike - thanks!
Raymond - thanks for your kind compliments! A tiny motor sure makes this kit look real and lively!
knox - thanks for your kind words. Your "zoom, zoom..." reminds me of the song "Super Bird" by Neil Sedaka singing "zoom, zoom, zoom, Super Bird". You know this song?. BTW, I'm a bit older and still zoom, zoom, zoom... around.
bvallot - thanks for your kind words. This kit is a motorized version by Tamiya. It comes with a tiny motor, wires, battery box, base, etc. What you need extra is an AA battery. This page shows all parts & instruction sheets of this kit:
