Re: [FTC]: Email Blast: FIELD MANAGEMENT FORMAT FOR FTC WORLD CHAMPIONSHIP

It seems to me that they need to allow one more person at the field on each team to monitor the FMS, including starting, stoping and watching for it to get out of control. Also the logistics of...

Re: [FTC]: Florida FTC Championship - Live Webcast
