5. 執車 gal (s) would be much better boys ...and all must be hot
6. more mud/clay layer on the surface to make the track less bumpy, which would be more suitable for 1:10 buggy.
7. use hoses instead of used tyres at corners.
8. fill up the trench at the perimeter of the track.
9 build a simple driver stand at about 2M high. then current blind spot could be eliminated
10. Size of the current prototype track is pretty small for 1:8 size. Suggest to refine surface condition this track for 1:10 buggy/truggy only. GP or size> 1:8 reserved for the new bigger track in construction
Anyway appreciate your hard work and passion
Carry on Angus.
