LOL might help if I came back to the thread I started, been busy messing with new PC, converting files etc.....
Any way, the squat magnets are literaly useless... you might notice a .001% difference... as for hardrive magnets, my magnets ARE the type of magnet used in hard drives... although some drives use similar but not the same type... they are stronger cuz they are larger... the more magnet you have the stronger the magnet of course... reason the squats are useless, they are too small, and too far away from the armature, and have to go through a piece of metal (the motor can) to get to the armature by the time all this happens there is virtualy no magnetic field left in the armature...
I only got these magnets to resell for the Mini-Z, cuz of the squat magnets being so weak, useless, and expensive for the cost, I set out to find the same magnets cheaper, and wound up getting entire magnet replacment sizes for the same price, and still cheaper then the squat disks were when they first were released (about $12 for squats back then).
In the Mini-Z X-Speed, my neos will DOUBLE the torque... but the RPM will drop about 25%... if you play with the gears you can either trade the torque for RPM, or just keep the torque.. as is, depends on the use... but if the x-mods gears are weak (i have not even seen an xmod offline yet), then it might be a bad idea.. lol.. unless alloy/nylon/delrin gears come out...
I rate them as being able to hold 1 pound... but this is to a small tiny contact patch to the magnet, if i were to maximize the contact patch to the magnet/item its holding, I could do well over 5-10 pounds.. with ONE magnet in the pair... they are Gauss: 12600~12900 or Tesla: 1.26~1.29 ---- it takes 1000 Gauss to erase a credit card... lol
(going by that myth busters episode).
