RE: EP Expectation Questions
Whenever you buy a plane with an engine or a motor included you get the minimum motor that will make the plane fly. Your motor will just barely fly the plane on that $12 motor. Seven cells would be better but a better motor will do a lot more to help fly the plane. 45 seconds is too short a motor run. Did you break in the motor? cycle the battery pack? are you sure the pack is getting fully charged? The cells should be almost too hot to hold after the motor run. If not I am guessing they were not fully charged. In the air (flying) the motor will run longer than in a static test. When i furst got into electrics I charged my pack a few times and each time the run was shorter. Wondered why untill I tried to start the car. I almost killed the car battery! After charging the car battery it charged the plane battery pack fully.
