Hi Cliff,
Extreme robots have a lower tip speed limit for HW and MW. For FW there is a 250mph tip speed limit as per Robot wars for HW. Extreme Robots are holding 7 events this year and Robochallenge 1;Insomnia.I believe Robots live will hold 3 open events(non spinner)

However Robodojo will be building a spinner capable FW arena, funding is in place and we have quotes from suppliers the only delay at the moment are the event commitments we have at Team Conker through August and September. That said we intend to hold our first FW event late November early December. After that there will be at least four events a year to justify the expenditure. That woiuld make 12 FW spinner evnts next year if the current sequence is repeated and just 3 non spinner events. Hope to see you at the Robodojo event next Sunday when I can give you more detail.
