I have no doubt a magnetic motor could out do a recip. Just like a turbine can. But that is all too easy, it is like cheating.
Just like say, that in the future there are vehicles that travel at or close to light speed. Since they all do it where is the race?
Its just more fun for the people doing the engineering and the spectators to see and hear something that is "OLD" doing what it shouldn't. That is the main reason the other prime movers are pretty much Garbage when it comes to motor sports. What is fun? It is when you see an old Allison hydro that's beating the turbines, that is a race worth watching.
Unless people into the electric / magnet motor camp get their heads out of the box that prime mover will never replace mineral fuel burning engines, because batteries are not a good power source, it just takes too many. And they always seem to need a good old heat engine to keep the batteries charged.
You'll get your chance, smart guy!
As for me I like the sound & smell of the big P&Ws,Merlins & Griffons but if they want their own class let them race electrics, drones & even sani-huts. During those times I can walk the pits,visit vendors or have a cold one. Just don't replace what a lot of us come to see,real race planes.
My ideal would be to see the electrics race with the unlimiteds , at least while they have comparable performance. It will become a matter of pride for the ic planes to beat the electrics which may lead to better performance in both classes.
As we would expect the electrics to be slower initially they would probably start off with their own races, but I cant see many people complaining if they were allowed to compete in the unlimited class, when they are able to qualify at realistic speeds.
"DeltaWing and DHX to shrink electric vehicle motors without compromising power"
"Before the end of last year, the flying test bed had opened a new page in the record books by setting a new world climb record, winging its way up to 3,000 meters (9.840 ft) in 4 minutes and 22 seconds – a climb velocity of 11.5 meters per second."
"On March 23, at the Dinslaken Schwarze Heide airfield in Germany, the Extra 330LE managed to top out at 337.5 km/h (209.7 mph) during its 3 km (1.8 mi) straight line flight, 13.48 km/h faster than the previous record set in 2013. The new record has been officially recognized by the World Air Sports Federation (in the category "Electric airplanes with a take-off weight less than 1,000 kg")."
"The e-plane also clocked a new world record in the "above 1,000 kg" category with a modified configuration, achieving a top speed of 342.86 km/h (213 mph)."
...for the sake of 'Ready Kilowatt', let it GO!
