So this is an old thread which I'm digging up in the aftermath of the recent new series. I've a few questions about vertical spinners which I'm hoping 9 years of experience can answer.
1. Are they legal or not? I'm getting mixed messages across the forum, the "rules" and what I've seen on the show. I appreciate the arena operator has the last say but the TV series was PACKED with spinners which seemed to violate 2 if not 3 of the rules applying to spinners.
2. This energy calculator on the teamchaos site- do they have a version in metric, or at least specifying what units are being used? Has this calculator been proved to work, what margin of error have people observed?
3. Earlier in this thread Richard from 13B appeared to basically justify why spinners should not appear at all...which is concerning. I want one. He predicted the possibility for a spinner to damage the arena and or send shrapnel at polycarbonate piercing speeds. At least one of these came true during the recent series, (see how I avoided the spoiler there), on this note, are they being considered for banning/regulating further to the '3 Rules'?
4. If I went with a 700mm disk diameter saw...that allowed or not? If not technically storing kinetic forces for impact purposes, but instead a glorified circular saw blade...still counts as a spinner, or a saw? Loophole?
5. Anything else anyone can give in terms of advice. Disk-edge mph optimums, material choices (hardox for everything?), motor protection tips etc.
