I read that thread also about using mixing instead of adding right thrust to the engine...

From my point of view... I have to ask... WHY??

They both do exactly the same thing... and I'd go one further and say that right thrust added to the engine is AUTOMATIC... for example... you adjust the needle valve on your engine and it's now turning a different RPM than what you did before. With right thrust, the more thrust the engine puts out, the more it pulls slightly to the right to counteract the left turning tendencies of the engine. IF you set up rudder mixing with throttle, and your engine is putting out more or less than what it did when you set up your mixing, you now have a funky flying airplane because the radio doesn't have a clue how much power the engine is putting out... it is just adding rudder in a corresponding amount to throttle setting... with no regard to the actual power output of the engine.

I know that Chip has a lot more clout than I do and could out fly me any day of the week, but I think his idea is just a way to get off the building board and into the air a little quicker. Anyone who is familiar with programming their radio could program in that mix in about 1 minute, and then tweak it once they get out to the flying field, whereas it may take you 30 minutes or more on the building board to get your engine properly set up with the correct amount of right thrust built in.

But once your engine is mounted right, it's always right. If you mix rudder, it's only right when everything's right... if the engine is a little bit off on power output (either higher or lower), then you're yawing through the air when you shouldn't be, draining your battery pack and stressing your rudder servo needlessly.

Chip's method is just letting the computer in the radio do work that should have been done by the human on the building board.
