Yeah, I didn't do that today. I used 120 knots, and a +1G pull. Although I did push the nose over to maintain Vy after the initial zoom.
A pre-zoom speed of closer to 140 knots works better. I will try that next time we run these tests.
I was just thinking about our error-laden checklist showing Vy (should be Vx) as 75 knots in the -8A, and I wonder how the original builder arrived at that number? Are they using the actual indicated airspeed in our aircraft, or is that some ideal number from Van's?
Given the extreme deck angle we experienced doing a Vx climb, I wonder if it's possible that number is bogus?
Hmmmmm. Something else to test.
I think you haven't been in a real high performance plane before which is why you think the deck angle was so unbelievably steep, it also makes me believe you haven't done any power on stalls in your RV yet which you should have done long before these climb tests.
