Isn't it more important to worry about lowering the collective? Cause what if there is engine trouble anyway - full throttle might not do much for you.
I think it should be simultaneous - any hesitation waiting for the throttle to go full could be deadly. I did it and its not that hard to go full throttle while lowering the collective
. lol.
You guys know wayy more than me probably though(besides maybe actually doing it), so thats just what it seems to be from my pov.
