I am having a problem with spur gears with the 2250. I put a brand new one on it and it rolled 3 ft or 1meter. It tore all but 4 teeth off the spur. I am going to try some other spur gears now. I still have not got the cog straight but I will. The spur is not surviving now. The 2250 is down right a power house. I think the motor is going to spin if tires, rims or shafts do or not. It even spun the pinion on the motor shaft with a flat spot on it. Gustav is right on the 5mm shaft.
