RE: Engine mixture or top end pitch? ..or throttle??
Damn tippy, can I pull the knives out of my back now?
I just mean, IMO, it's best to start with a certain setup and stick with that. if you learn to hover at 50% for 2-3 months then switch to 75%, there's going to be a learning curve to readjust.
I personally use 5/8 as my hover point. It brings your +/- hovering pitch closer together and still gives better resolution on the rest of the curve.
This is only my opinion.... don't flame me please. [:@]
