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.

Re: What NEW Vex Accessories Would You Like TO See?

I'd really like to see quadrature encoders, I can't imagine them adding to the cost that much, just add another photo interrupter, and have Intelitek implement the quadrature encoder the same way they did the one included in the kit, except for counting down when going in the opposite direction.
I also agree with the addition of pots, you could make your own "servo" except gear it however you want!

Re: What NEW Vex Accessories Would You Like TO See?

I felt that the EDU chain works a lot better than the VEX chain. maybe bring back that chain to use in the kits. Also, the drive screws need to be tougher, or the allen wrench for them needs to be better as only those screws seem to strip really freaken easily, even without torquing the screw or tightening. A nice assesory to add would be a worm gear configuration. It would be great for making an arm with a lot of weight.

Re: What NEW Vex Accessories Would You Like TO See?

I also think some sort of all thread should be added so that you can splice the "beams" togather (beams). I found i ran out of these long beam rather fast so splicing a few little ones would be a quick fix before buying a hardware kit or something else.

If you mean connecting the beams together then just use the 8-32 Coupler they sell on the page you linked to.
