I snapped an arm off my new Hellbender 122 V2 after a high speed run through some trees. Unfortunately it ended up running into a tree and then hitting a thick cable holding a telephone pole up. This snapped the #2 motor arm off. As noted on their web site, this frame has a warrenty. I contacted RMRC on 11/23 in the afternoon and they promptly responded with further instructions. They processed my warranty ON THANKSGIVING DAY and shipped my new main frame out on Black Friday! Now in less than a week I'm rebuilt, just waiting on a new motor. Thanks RMRC!
