I find UAV engines to be fascinating but don't consider myself particularly educated.

I did find it interesting that there are a lot of UAVs powered by our friend Felix Wankel. The fact that they produce more h-pees for a given engine weight apparently was very appealing (also the lack of smog testing)

Very TRUE. I knew quite a few guys who ended up torched by their beloved Mazda engines that suddenly failed them (too expensive to repair) in the late 70s/80s. My brother one of them. He absolutely loved his RX7.
What is mind blowing to me is I found out near a million of them were produced and sold. Only to end up another in the dust bin of automobile history. Why? I have no idea what went wrong. Possibly vastly misunderstood or non accepted new technology?

Maybe a tad similar to G.M. Corp 1950s era fuel injection engines that were ahead of their time and worked great. Drag racers loved them. Joel Rosen of the world famous Motion Chevrolets was an early owner of a fuel injected corvette (his personal work ride) and a master mechanic at keeping them running who too eventually gave up on them. The long story on the Chevy FIEs was that the mechanics hated working on them and there were not enough sold to make it feasible to invest more into the training, maintenance , diagnostic tools and machines at dealers etc..... They just would not sell well at that time. Just like Chevy, Mazda seemed to have their hands on some good technology they let slip by for some reasons...? It is interesting to note that no other major manufactures have tried since. Little surprised Toyota did not jump into some of the technology learned from Mazda... Toyota seems to be one of the main automakers on the planet willing to take on and try to perfect all sorts of new technology for years.
 
Fuel efficient drones?

I don't know that I would ever call Felix Wankel a friend, he was an actual Nazi.

Having said that I did own a Rotary powered Mazda.

I have a few of those shirts. I will wear them on Saturdays when I work because they are funny. Smart customers get the joke.

Back on topic, how do they get to run a 2 stroke, but Supercross has to run a 4 stroke?
