EVTOL's and battery drain on lift-off - one could amend glider-launch methodology by attaching the aircraft to a large helium filled balloon. Said balloon is attached to a winch, winch ratchet is released, up goes balloon and EVTOL. At a a suitable height, pilot pulls on the release handle and zooms away. Balloon is then winched back down ready for the next customer. Problems solved!
Hmm, maybe I should patent that...
