I’ve seen a lot of team using sprocket, but low-profile chain (slightly smaller chain but still work with sprockets). This not only saves weight but also space. Did you know where to order this?
Our robot is bulky so saving a little space/weight is everything we are looking for.
I haven’t looked much on the store for a low strength kit, but I know what you’re talking about. Take a look on EBay or Facebook marketplace for cheaper vex parts, and if anything ask instructors in your area if you may purchase excess!
I would personally get the 6P sprockets. This is because they are smaller lighter and surprisingly durable. DO NOT get the 3P sprockets. Those things snap super easily.
