Right been down to goshen and here's the feedback...
1 the sand is insane, clearly the wrong sand for the carpet pile, protect those electrics as much as you can, b44 guys won't need to worry but myself on two occasions got sand between spur and pinion causing damage.
We really need to shift this sand, when it's sorted though it's going to be awesome!
2 stones, we need a 15 minute team effort to remove the larger hardcore stones, it's a quick job.
3 fencing on the fence needs putting up and the shop end as I flew through it
4 tyres.... Spikes are a must anything else and it just skates on the surface.
5 we need to pin the carpet down as this hasn't been done, due to size I would normally put about 250 - 300 pins in there
The main issue is the sand and protecting the electircs and gears. Before we race we really need half hour with blowers and brushes to clear as much sand as possible!
