The down load on the tail is lower. Thus the total weight which the wing needs to support is lower. Since the wing is carrying less weight it will have a lower stall speed.
I understand why an airplane is faster with an aft CG,
but not why the stall speed is lower. ??
You lost me on that. (my failure not your example)
Pictures always welcome.
Bob,Before we quit - Do you think an ordinary Citabria can go flat in a spin?
Here is a good explanation
https://www.flyingmag.com/safety/accident-investigations/unrecoverable-spins
Bob, I've spun a 150 Decathlon many turns, many times and often with an adult male in the rear. By 3 turns it's as wound up as it's going to get, and I've never had it try to flatten out. Because of the way I was taught, I always recovered with positive/assertive control inputs, but I think if you just let go of a Decathlon it'd fly itself out of a spin. I don't know how the airspeed would stack up, but I think it would stop rotating and start flying on it's own fairly quickly.I own a Decathlon - not quite the same. I am not wild about multiple turn spins, so will be doing no exploratory testing. Just wondering if these fine airplanes can go flat?
No - I rarely do more than 3/4 of a spin.
But I have heard stories of folks who like to count the turns - I understand the impulse to make/break records (yesterday I did 42 Stearman landings) - but my impression is that after two or three turns a spin will tighten up.
We had a Citabria fatality last month - extremely experienced instructor; object of the lesson was CFI spin certification. I have heard almost nothing - one pilot suggested a low level engine failure and an unsuccessful landing - but I initially wondered if it hadn't spun in?
I own a Decathlon - not quite the same. I am not wild about multiple turn spins, so will be doing no exploratory testing. Just wondering if these fine airplanes can go flat? Pretty sure a Cub can get into a difficult-to-recover spin with a heavy guy in the back. Not gonna try that either.
Hold a gallon of milk at arms length in front of you, now hold it close to your chest. Which is easier

I don't drink milk.

How much dihedral did you dial in?

It also works with oil and Johnny Red with a handle
