"The other half of the equation is that it has to spend its time on the flight line, not in the hangar. The Grob products and I mean all of them, fail in this regard.
Electric power plants are IMO, the future for flight training. The duty cycle is well suited for this type of propulsion....."
The only concern I would have about electric in a flying training environment is the time taken to charge. It's difficult to squeeze power in any faster than currently and this will impinge on turnaround times and achievable sorties in a day.
