Couldn't resist getting this device ---it is as much fun to build as it is to operate.
The instructions are perfectly clear and accurate, very well written, but be sure to follow every small detail of gear color, sequence, battery terminal alignment, etc; patience is needed especially with the small hex nuts which can drive you, well, nuts. Totally satisfying.
