Just been out for a blast. Was starting to wonder about the mysteries of age and legs and dropping bikes and how it was possible. **** but it runs well on the Road5/EMAX combo.
AND THEN I wandered into a business park where they were doing the roads - OK now I remember all about age and legs and weight - thankfully not dropping bikes, though.
But cannot give up the R3 just yet. In part because it is not, per se, 100% road legal.
