So at least you now acknowledge the existence of a suitable motor with an appropriate continuous rating.
hmmm, not quite - 5 mins at max continuous isn't going to cut the mustard in pretty much any helicopter role and a 20 minute max life????
Why haven't Extra elected to use a generator with a prop in the slipstream on it? Cooling issue perhaps with going longer than 20 minutes?
It is a small step in the right direction but a very long way from challenging a conventional TR.
