RE: ***Official*** 1/18 Scale HIGH SPEED Thread!!!
I have an Xray M18T pro which is currently geared for about 45mph, because I like to get at least one battery through it before I have to wait for it to cool.
It currently sports a Team Orion Vortex micro speed control and motor combo at 7500kv and runs on 3S 1600mAh packs for about 20-30 minutes. Gearing is stock steel spur (I forget how many teeth) and a 10t pinion. It's quite ridiculously fast. I also have the foam monster truck tires for later speed runs, which will push the speed up about another 10% due to the increased diameter. The motor finishes a battery at about 170*F, so if I gear down (for more speed) I'm going to have quite a bit more downtime (waiting for cooling).
I'm still waiting for a body. When that arrives I will post pics and vid.
