Daryl's Ninja is acting up, but thats because he sucked in a tablespoon worth of sand................. Ninja's are wicked motors, easy to tune and excelent powerbands.... the person who is having issues is a personal freind of mine, who really has no experience tuning an engine.... His 28 did fail, but it is under warranty, hos .21 is all lack of needle turning.....
