Shameless update from Dale Kramer

Andy, I see that you have excellent experience and obvious insight as to what hurdles I will have to overcome in order to transition at slow airspeeds..

Before I continue I just want to see if you agree with me that it is less critical to iron out these 'low' speed transitions IF #1 the transition to horizontal flight instructions are simply to accelerate vertically to, say 40 (or whatever testing dictates) knots, then slowly push over AND #2 the transition to hover instructions are, apply WOT electrics, do a zoom pull up to vertical from 100 knots and on the way up, when the airspeed is less than 40 knots apply WOT on the Rotax?

Sorry for run on there, I am just trying to present transitions where there is less need for calculations.

And, if we agree on that, the minutia of how slow of an airspeed before pushover and how little zoom altitude is needed can be determined in testing.

I think your simple calculation does not take into account enough variables, mainly airspeed before pushover.

I am hoping 1.3/1 thrust will be adequate but I have ideas to get more if needed.
