Electric? - as Jab has shown, the students seem to want to learn in a "proper" looking aeroplane. And I assume that the training market would be your target, with swappable batteries sitting at the "fuel shed", ready to go.
Electric seems a good proposition for short training flights. In a Jab airframe! (Note. Please activate your humour subroutine)
An advantage might be the lower noise- many strips can't allow flying too early in the day in case it wakes somebody up.
Also, training schools are more likely to appreciate the entire operating cost, and see the potential for offering cheaper hourly rates. I'm expecting the higher purchase cost is offset by cheaper fuel and engine maintenance cost over the life of the batteries and motor.
