I was just wondering what people thoughts on how one would gear a 8 Motor drivetrain to fit under the net for over under. Of course it is easy to gear it but what gear ratio would yall recommend?

A decent gear ratio would be 3:7, and would probably be good for both a speed and torque based drive train, depending on which one you want. It’s pretty good, and decently fast.

Run 450 imo. Very fast, which is good for 8m drive, and pretty easy gearing.

One of the best teams out there right now runs a 600 RPM direct drive, as seen in this video [Pits & Parts | 9364H Iron Eagles - HailStorm | Over Under Robot]

I’d do 480 3.25 (48/60) on 600 RPM motor s

We are using smaller diameter wheels so it will travel faster, gears wont fit but i get the ratio

Direct drive is alright but has more issues, also they are using chains which absolutely suck, im thinking around 400, I might end up gearing it using 24:48 or whatever that tooth gear is with a green motor casing and just gear it up. We are using smaller diameter wheels so anything over 400 seems v…

Uhhhh, that’s not how it works. The smaller the wheel diameter, the slower you will be (less inches traveled per rotation). If ypu’re using 2.75 in wheels, [image] Catalogue of Drive Gearings Technical Discussion Due to frequent questions and discussions on drive speeds, …

It will be slower but the acceleration will be higher which is what we are looking for in vex because the field is so small. I realize that I didn’t specify that it was acceleration

60” per second is awful, most teams are running at least 64. To play good defense you need to be fast enough to keep up with other bots, and at 8m you have way more than enough torque to go faster. For defense, 450 on 3.25s I think is the best all around ratio, just will give you less space so mount…

I mean there is always 480 on 3.25

(I would recommend something around 60 in/sec)
