Here is one possible idea that could be fun--using the same logging devices that are being used for F5B gliders, measure the total electrical energy used to complete the task.Using energy and time combined to determine the score would make for a interesting event. In addition landing off field would be unnecessary since the motor could be restarted to get out of a bad situation making more areas available to eXC than are to winch launched planes.
The energy information can be easily read from the onboard logging device or can also be sent down to the ground by telemetry using the data link built in to newer radios or by a separate transmitter. I have been flying such a device for nearly a year in my F5B glider and it works fine. In the stand alone version only 2 connections are needed to the power leads between the battery and controller.
Electric power could open up eXC to other planes that would not normally be considered a XC suitable. Smaller planes like the Aspire and other F3J planes could be pressed into use by those wanting to give XC a try.
Wow!!!!! GREAT idea!!!!!
Using total energy used to complete distance and speed,,, very cool
