Spur gear stripped on mine while testing the SpecR axles. Couldn't get the stock 66t so went with the 75t. Drives better.
Wasn't suprised that spur stripped. I've run more 3s then 2s.
Tires at still terrible. Just too soft, no consistent traction. Can't imagine what surface they were test on. Think they were picked for looks, not function.
Gonna try running different body first. Porsche body stills feels tail heavy when driving. Have to keep shocks stiff do body doesn't hit pavement.
