Hello all 🙂
I’ve made several antweights over the years but none for the live scene, so wanted to know some basic safety questions so I don’t get caught out when I eventually go to one.
1: Do antweights require a fuse of some kind, as I’ve found no info about this?
2: Do antweights need dedicated power lights, or does the light on an ESC ect count for this task if visible?
3: Does the 250mph tip speed limit apply for this class, or is the rating slower for safety reasons?
Any advice would be appreciated 🙂
Cheers,
Jon

Hola,
To answer your questions,
1. No fuse needed
2. ESC light counts, just needs to be visible
3. No tip speed limit for now
Hope this helps

Don’t think there is any requirement for LEDs at all is there at ant weight?

I’ve not seen any rulesets that require a power light on an Antweight.
FRA build rules do technically require a power light on all weight classes, but practically all Antweight events use either the AWS rules (which don’t require them) or a derivative thereof.

It’s also worth noting that Antweights don’t require removable links, a simple slide switch is fine.
From the AWS rules
> 2c) Robots must have an externally accessible way of being shut down (e.g. a power switch, removable link or battery plug) that can be operated without tools.

[bbb.gd/antrules](https://bbb.gd/antrules) - we’ve tried to collate all the variations in UK rules here as some events follow AWS rules, some follow FRA
But for your questions - no fuse or powerlight required, no tip speed is true across all events currently.
All events are strict on spinners needing a power switch or link, less so for non spinners.
Locking bars are welcome but again not currently required (I think they’re getting more common at Dojo?)
I need to clarify with EOs running FRA rules as some of the safety stuff for beetle and up doesn’t seem to apply.
