The only time I mix any elevator in for landing is with the flaps switch or slider just to prevent ballooning. Otherwise, I want to have the control of the model - not rely on the transmitter. Suppose someone barges towards you or you have to do a power on wave-off? I don't want to be futzing with switches in an emergency situation. Also, landing into calm vs. strong winds - doesn't that alter your elevator needs?

I do have a landing switch for the throttle that is the lowest setting. Off I can't accidently powder down so much it dies on me and it is a good taxi setting. On it is very low idle. Switch beside it is engine kill.
