So I want to make an external image stabilizer for my camera, but I don't want it to be some huge thing that requires an massive SLA Battery or hard drives. What I'm trying to figure out is, where can I find a motor to give me upwards of 10,000 rpm and where can I find a couple disks that are heavy enough to actually stabilize something, and how can I make this as compact as possible? I'm thinking of a pancake sort of motor with the spinning disk as the motor "shaft," and that way the spinning disk could be in the smallest space possible, but then with the battery, I was thinking a LiPo type battery used in model airplanes. Ideas?

if your meaning to build a mechanical precession stabilizer, why bother? youll eat batteries, LiPo's are the most powerful, lightest and most enrgy dense batteries, but they are also the easiest to kill, one or two deep discharchges and thast battery willl never be the same, even if it stilll works.
i would favor using some MEMS gyros countering with some RC servos. youll need an embedded system though, like a pic or cortex M3, Arduino or whaterver suits youur liking.

The easiest steadycam rig is to put a heavy weight hanging well below the camera on a rigid post. Most professional steady cams use that to keep the vibration down then they add on all kinds of crazy iso-mounts with springs that move the weight away from the operators arms.

The system wouldn't need a very big motor, and I would most likely be using the rig with the LiPo's in the field for pictures and have a push button switch to activate it. The only reason I suggest them is because of their weight and power. I'm not planning on having a very big load on them anyway. I would like to do this as simply as possible, and as light as possible, so no MEMs, and no large weights hanging down from the camera. Most of all, this is a proof of concept project that would be interesting to do.

IF you are set on motors then you can go with brushless hobby motors + speed controllers. They are very light, strong and are meant to be powered from LiPo batteries.

Optical sleds from old CDROM drives? Mount lens on three of these with pivots, and it has 3DoF. The driver doesen't need to be particularly complicated, even a simple H bridge will work.
