I've been flying electric powered high performance model airplanes (mostly F5B class) for decades. I'd like to think the electric r/c flight industry has been trenching this territory for quite some time. With the next 2x improvement in battery energy density cars and possibly full scale planes are going to make a huge leap forward. Here's a video of F5B class R/C planes. It's hard to convey just how insanely fast these things are. Huge power to weight ratio and very aerodynamically efficient. You can hear the crowd gasping at the performance they see. Also note that the motor is only turned on for a second or less at at time. If the motor were on longer these planes would reach 1,500 feet in 5 to 10 seconds tops. https://www.youtube.com/watch?v=T0z9iy2SJA0 https://www.youtube.com/watch?v=T0z9iy2SJA0
