Do you mind sending a few to me?

This mod replaces the stock magnet with a neodymium-iron-boron magnet more commonly known as a rare-earth magnet. The replacement magnet is the same diameter as the stock magnet, but half the height. Combining two of these magnets gives the proper dimensions necessary for replacement. Magnets are often measured in units called gauss and these rare-earth magnets offer a combined measure of 21,600 gauss vs. only 2250 from a similar sized ceramic magnet.

What about increasing the current through the coils? I forgot all the things we learned in physics about magnetic fields but would this increase the strength of the field?

well i just got my REM. 1.99 at radio shack. i am quite disapointed. the rem can barely turn the wheels, when im holding it off the ground. and does nothing for it when on the ground. i have tried repositionig the magnet.. everything. what a waste of 1.99
