ROAR offer clarification on LiPo cells


We reported earlier this week about the decision by ROAR (US governing body) to ban all LiPo cells outright. They now offer some clarification on that decision and whilst their ruling on banning LiPo’s powering electric motors is final, they are still investigating whether or not to ban LiPo receiver cells or not on the grounds of safety.

For 2007 Lithium Polymer batteries are not permitted to compete with NiCad or NiMh batteries in electric class racing because the voltages are not equivalent nor do the pack dimensions match those currently observed by ROAR and IFMAR. This rule does not currently affect receiver packs at this time, however ROAR is concerned with the overall safety of these cells when located near or around flammable/combustible materials. ROAR will investigate this further.

So you can, for the moment, continue to use LiPo receiver cells at ROAR sanctioned events. We will keep you posted on any further developments.
