They'll also be made out of 1/4" plywood, and we'll be getting some lithium batteries. So not super heavy in other words. We're going to make some gearboxes out of plastic, probably acrylic, to gear them down. We don't know how many new students we're going to have yet, so that will dictate how many drivetrains will be built.
Thanks!

I sent a chat to the person in charge, I'll let you know when he replies.
24" x 24" seems way too big for a chassis made of throttle motors. IIRC they have a max output power of 20w, which is 1/15th the output of a CIM.
2 cims can make a 120lb chassis go at 8fps easily. If we follow that, then we need 30 throttle motors per 120lb, or 1 throttle motor per 4 lbs.
I'm disregarding a lot of factors here, but you may want to make a much smaller chassis on the order of <30lbs just to be safe. Will you be running FRC control systems or just RC?
