So for a while I have pondered the idea of recharging a rc plane in-flight. So far I have a rough idea of how I would do it. So the plane that has the extra batteries and charging boom would probably be a vastly modified guinea pig or custom cargo airplane as they would have the capability to carry the extra batteries needed to charge airplanes. The conectors would have two main power supplies one for powering the airplane while it's batteries are charging and the other power supply would charge the flight battery. There would also be a small power supply that would operate a switch to stop power coming from the planes battery and instead from the Charging plane. The conectors would have small neodinium magnets to hold the connection tight. For the power conectors copper pads would transfer the power from the charger plane's conectors to the plane. The pads would have springs to insure good contact. I think this would be better for some of the larger autonomous planes like some members of the community have made. I plan on having a cad model at the end of the week. Any suggestions or recommendations would be appreciated. Thanks and Safe Flying everyone!
