Dadgum that is some High RPMs
Never try to tell me it can't be done
When I have to paint I use KBS products
I guess it isn't very good, the truck didn't take off?
Is it battery-powered? If not how do they power it? Maybe start off of batteries and then generate enough power to keep it running? Wonder how long before we can get one at Harbor Freight?
That was the fully battery life, time for a 48 hour recharge.
I just found my fathers pilot log from 1940 when he was apparently upgrading his license. About 90 hours logged with lots of pylons, spins, stalls, etc. He eventually had multi-engine land and sea rating and was part owner of a C-47.
Interesting that some of the handwriting looks like mine, but I wasn't exactly around in the 1940s.

I also wondered about the power production to keep it running. The trouble is that to my knowledge, nobody has defied the persistence of energy laws.Originally Posted by VinnieL

Batteries....Lithium to be exact, with a new chemistry on the horizon that may make the same leap ahead of Lithium that Lithium made over Lead-acid.
May 28th a Cessna Grand Caravan flew for 30 minutes on battery only using about $6 worth of electricity. They are currently working to Make 100 mile shuttle fights with 3-4 passengers, with a 30-40 charge time between flights.
35 years ago when I was into R\C an electric model was good for about 2 minutes under power and about all you saw was poorly performing gliders because they were heavy, but less messy than nitro burners.
Most of the better drones can now hover with flight times in excess of 15 minutes.
I read an article a while back about a rental service that uses Teslas and is actually making money on them because the lifespan has far exceeded that of a gas car with less maintenance.

Speaking of Teslas, the taxi drivers at Schippol airport in the Netherlands almost all had Teslas, and that was back in 2017.
