JOINT STATEMENT FROM UK BEETLEWEIGHT, HOBBYWEIGHT & FEATHERWEIGHT EVENT ORGANISERS
As you should be aware, the UK beetleweight, hobbyweight & featherweight ruleset dictates a tip speed limit on all spinners of 250mph. This limit is set for purely safety reasons, as we are reaching the limits of what some of our arenas can currently handle with some recent near breaches. If we cannot run events with a guarantee of safety, we should not be running events full stop. No robot is worth more than the safety of the people in attendance.
To this end we have been disappointed by recent events where it has been found that some may intentionally be operating above this. We have worked on a trust system for some time now but unfortunately and hopefully understandably this must now change, putting a larger workload on our event staff.
We will be paying particular attention to spinner tip speeds going forward, using multiple methods including but not limited to asking for theoretical tip speed calculations, spot checks of components, tachometer readings, transmitter inspections and frequency monitoring using microphones in the arena.
It goes without saying that anyone failing or refusing to take part in any of these checks will get a unified ban from all our events for a set time period (up to permanently) and evidence given to the FRA should they wish to take it beyond an event ban. It is the roboteers responsibility to ensure they are compliant with safety rules at all times. Honest mistakes may be excused at the discretion and judgment of the event organiser. If you are unsure, we have made a tip speed calculator here: bbb.gd/tipspeed.
We know this will only apply to and affect the smallest minority of people and on the whole, you, our community, are incredibly supportive of upholding all safety rules, and we thank you wholeheartedly for your continued support of our events as without your assistance it just wouldn’t be possible.
Thank you,

If you're unsure of pulley diameters but know your reduction ratio, use this instead. For example 5:1 ratio, put 5 as the output pulley and 1 as the motor pulley.
