Its been a while

Ran Spur 4 at a live event with the temporary wheels , they were awful
It also broke a pinion weld and went down to 3 wheel drive

Rewelded the pinion
Replaced the wheels with contact wheels - strangely 100mm wheels are quite expensive and took time for them to come from China
When they did one didnt match, so had to re-order to get 4 matching
Finally got a full set
