had a good day at the track today. I went to a 60t spur and 15t 5mm pinion with adapter. No issues with dogbones/spur gear/pinion/ or slipper. Truck ran great. There were 3 sc10 4x4s there. All running castle 1410s and mine was the fastest out there. I spent a lot of time driving my losi eight e 2.0 and have to say I love my SC10 4x4 more then my 1/8 scale buggy.
