Seriously. its not very reliable. too much skipping. not being able to gear for speed very well.
I really would like to see a much higher speed/smaller and more torquey motor as well
Worm gears. for sure.
I'm liking this less expensive pneumatics idea. maybe smaller cylinders as well? (2 speed trannys?)

If used properly, the Vex chain is very reliable, plenty strong enough, and won't skip teeth on the sprockets. It all depends on how you use it. You need to have the chain properly tensioned, because if the chain is too loose it will skip, and if it is too tight it will snap. Between those two extremes the chain in the Vex kits will perform well and can
lift several pounds of Vex parts easily.
The pneumatics kits can't really get that much smaller, as they are only 10 mm bore to start with.
And if people really want different pneumatic cylinders, why not just buy them directly from companied like
Bimba or
SMC? Bimba sells 5/16" bore single-stroke and double-stroke cylinders for $10-20 each, with each additional inch of stroke costing $1.30.
