I just looked through the rules again, and they were changed.
wasn´t it 2000 rpm before? now its only 500???
although mine will only have about 200 rpms, and i will make my weight (somehow). It made me a little worried about the size of my spinner.
so the question without putting out any details:
1. 200 rpms
2. 20 kg
3. any size spinner i want? :ja: ???
