My team uses a 360rpm, 3.25 inch wheels drive. Would you say just nice, faster, or slower
360 rpm on a 3.25 in wheels is about 61.25 in/sec.
That is on the faster side, but is quite competitive, especially with this year’s challenge.
we use that as well, its a good mix between speed and control. If you have a particularly skilled driver, i would go faster (400-415) as faster is better as long as you can control it. When you are driving with 360 does your driver feel like they could easily control a faster moving robot? If so, increase it, but if your driver is reasonably new to vex, stick with 360. In the end its all dependent on your drivers preferences and play style.
We are running 450 and I am able to control it very well, I’m only a 2nd year driver.
Depends, is it a 4-motor drive or a 6-motor drive? Both of them are solid, but you could go for a ratio with higher torque with a 4-motor drive, while I would recommend slightly more speed for a 6-motor drive. Both of them are really solid though, and I think that you’re probably good to start working on other parts of your robot. One thing that you might want to note, is that 360rpm on 6 3.25" wheels is a pretty short drive base, while 360rpm on 8 3.25" wheels is much longer, and nears the length limit.
A lot of other good drive base configurations can be found in this Catalogue of Drive Gearings
I might be bumping the wheel size on 450 from 2.75 to 3.25
are u running 6 or 8 wheel drive
8 wheel. Don’t worry, @Wesley13406D has made sure that we know all about his robot. In fact, he’s made a forum post about it 
We have changed a couple things since I put that post out.
great, 36T-60t sounds like the gear ratio you’re doing.
If you are talking to me, we are running 450 RPM on 2.75 inch wheels. The gear ratio for that is 36-48 powered by 600 RPM motors. The 36-48 requires the wheels to be either higher or lower than the motor.
