Do that, and make an air inlet that can be opened varying degrees at the front of the plane leading to the battery box, with a fan propelled by a pop up bicycle pedal drive. And at the rear of the box install an exhaust pipe out the the rear of the plane. Voila, a secondary thrust system.
Never let a crisis go to waste. (As demcomms like to say).
