Could you re-phrase your questions?

Ahhh yeah. Just realised you'd never hit the zero thrust speed. Woops!

And PS: yep, all of us light a/c folk have hit that. I think we've all
flown flat out, level flight. Quite a few light a/c are approved to run
continuous full throttle - doesn't do much on yer endurance or fuel
economy though.
