In other record setting endeavors, the Z8RC Champ 15e is getting nicely ironed-out. E-Flight tried to re-Christen the venerable plane the Ch-anvil, but we've managed to completely fix Horizon Hobby's latest binge of record-setting buffoonery. With more than 10 oz of E-Flight lead removed, in the form of their half-dead-weight Power 15 and recommended 3200mAh stone to feed it, this Aeronca Champ finally flies like a Champion. Video follows.
