An electric self launch Arcus 2 seat glider has a quoted endurance of 2,000 m of climb, after which you need a long recharge. That amount of climb should use about 5 litres of petrol in a solo engined version, which has a fuel capacity of 41 litres. So the electric version is heavier, costs a lot more and has far less endurance. Much as I like the quietness and simplicity of electric operation, battery technology has a way to go before electric self launching could be viable for a trainer.

Could be a glider like this be used as a trainer ? How many take-offs are you making on electric self-lunch before it give up ?
