We didnt even notice it with weight.
We didn't have carpet to practice on at home so even on pneumatic wheels we were turning on linoleum. Carpet DESTROYS dreams.
To the team in question:
A CIM spins at 5280RPM, 88 revolutions per second. If you are direct driving with your gearbox and 4 inch wheels, you are driving at about 23 feet per second. Much too fast. anywhere between 13-17 is considered "normal" in FIRST (high speed).
Last year we did the same thing on accident, and once you throw 100+ pounds on top and try to turn on carpet it becomes a HUGE issue going 23fps. We had to cobble together this ridiculous setup. Instead while you have time, I would suggest building some offsets for your gearbox, and either put another gear reduction stage in there, or use sprocket reduction.
