Say you have a throttle like that CH quad throttle, has 6 levers.
Say you map 4 of them to throttles 1, 2, 3, 4. Can you "just" map the last to to RPM 1, 2?
Will that mean RPM 1,2 are mapped only to engines 1,2 (because you have all 4 engines mapped), or will it do it as RPM left/right, as if you were in "twin" throttle configuration?
If you just had 2 throttles and 2 RPMs I can see how it works, but what if you had 4 throttles and 2 RPMs? Does that throw a wrench in the works?
