Hey. I have the Flyzone Cessna 182 skylane. It's the smaller, red one. Right now it has a 380 electric brushed motor with a Electrifly 7-cell 8.4V 1100mAh battery pack. It doesn't have enough power for my liking. Does anyone know a cheap, but powerful set up? I only want to replace either the battery or the speed control, but if I have to I can replace to whatever you suggest to me.
