Several of us flying the electric version with Eflite 60 or 90. There is guy who did the Saito 20 and said it was too heavy and wanted to snap on him on the turns unless he kept it moving fast. The article in FlyRC on the throws was dead on. Reduce the throws and a slight down elevator for initial flight. Like all Mustangs it wants to head left hard on takeoff. Gotta stay on that rudder. There is long thread on RCGroups for this bird. Jerry.
