Like to invite all to check out the uskra rules ..what a good set of no nonsense rules and easiest tech ive seen yet! All the rules and regulations were voted on by the racers themselves...anyone can go to their facebook page and print the rules right off the site..very nice easy access for any questions and a tech committee to handle any issues in a moments notice....very exciting to see this coming about to help level the playing field , save cost on built engines, easy building rules for a diy and give the racers a voice finally!
