Having raced one of the original ones, I found that I needed a second one just to have sufficient spare parts. The shocks used to jam if it was run in dusty conditions, and there was a huge amount of slop in all those rose joints (both on the ball/cup, and on the thread). Indoors on carpet the handling was excellent, provided you got it straight before accelerating hard (if you didn't, the inside front wheel wound start to spin and then you'd lose all drive).
Looked wonderful though.
