Ran mine for the first time at work, with the 540 6.5T and the 70A speedo, no probs with the speedo, however the motor was too hot for my liking... so will have a play after racing the buggy on Sunday, but going to order new Speedo and Motor tonight....
However the car was BRILLIANT..... must say it handled like a dream, took the bumps so well, and also got some air.... I am hooked....
