Secret Mazdaspeed Rotor
LOL - made you look. Check out the old Curtis Wright photo of their rotors: 8.6, 60, and 1920 cubic inch rotors. This is most likely a repost - but I could not resist seeing how may people would hit the thread 
Happy Holidays!

There is one thing about these old rotors that I just noticed that I've never seen anyone else mention. They are all side cut just like the Renesis rotors to allow slighlty more intake timing. That means all of these are side intake port engines. On the 7forum you will see people claim that Mazda copied this technique from some individual rotary tuners who do this. It's apparently an older technique!

holy !@#$.
The first time i saw the pic, I did NOT notice that guy there. I was taken by the varied sizes of the rotors. I had no idea they had made any that big. What the hell would they use those big *** ones for? I know, I am an ID10T...at least I can admit it.

In WW I, they experimented with rotary engine fighter plane, the problem is that due to unique characteristic of the rotary, it tends to steer to the right (i think). Very capable fighter though, too loud too! Once the fighter pilot got the hang of flying the plane, they managed to use the inherent problem to their advantage during dog fights

Sorry RX8 Fighter, wrong kind of rotary engine. In WW I, the engines used were radial piston engines. In some models, such as the famous Rhone engine, the crankshaft was fixed and the heads rotated. These are often referred to as rotary engines but are not the beloved Wankel rotary engine.
The rotating mass of the engine in these fighter did result in large gyroscopic forces. This made right turns easy and left turns difficult which affected the dogfighting tactics.

all propeller driven aircraft have to deal with newton's laws..it's worst with single engine craft, but it affects multi engine planes as well (i don't know how much, i don't have a multi-engine certification). that's why they have a verticle stabilizer.
wankels are popular in experimental aircraft because of their high rpm durability. you don't see them much on alot of general aviation planes because there's a limited number of wankel mechanics around to perform regulated rebuilds and upkeep of the motor
