D.O.
I know how to control the speed using the elervator, I'm just saying it's a waste of time and very backward when you're engine is on and giving you power. Yes, glide approaches it wil be mandatory, as I've done a couple so far. And decents as well, maintaining 65 knots requires nose up/down movement... not hard
But that's not my point, my point is when the engine is working and you have power, why not use it...
