RE: Throttle stick position while flying!!!
I fly about 9 different planes throughout the week here in sunny Florida most of the year.
I fly them about 6 different ways. The slow planes get 1/2 throttle or less, but I do slam the stick forward for take off on everything since I flew my first trainer. Maybe it's habit, but it works with exception of ME-109, and Cubs. Those I "push" forward with better results and lots of right rudder on take off. I'd never fly my F-20 less than WOT, it's just not that kind of plane.
I'm not a calm day only flier, so full power take offs put me in my comfort zone quickly, or at least I think so and have success with it. I see no reason to change that routine to get in the air with a lot of authority, but certainly WOT cruising doesn't suit every plane in my hangar whatsoever, not for aerobatic planes especially.
My most enjoyable plane to wind down at the end of the day of white knuckling a fast plane, is my Telemaster 40 with Satio 56, just 2 clicks over idle. In a stiff breeze, the ground speed can be in the negative. I've flown a full tank before without needing to circle around. I like zero ground speed touch and go's! Saito 56 flown that way yeilds a 25 minute flight. I refuel in 2 minutes and can do it again. That's fun stuff.
