Managed to get out again today but my tyres are still giving me jip. If there not coming un-stuck at the rims and tearing into my body then the taping belting and gluing are failing and i'm getting huge ballooning, Also lost my steering near the end of the run too. not sure what the problem is there yet.
Thinking of trying these bad boys. http://www.redrc.net/2010/10/vp-pro-809-blade-evo-808-gripz-evo-tires/
On a plus note I have found a lovely big long flat grass area to run on. So if I can get everything staying put 63mph + should be doooable.
