Possum:
Kolbs spin. Some better than others.
Feels like a spin, very vertical, almost like a spiral.
Immeiate recovery.
However, with Fergy wings and differently configured fuselage, I
don't know how your aircraft will react.

I've got Kolb ribs/wings thick & flat bottomed (this things 10 years
old) ...so I think it will not be so different from yours - just for
the camera anyway.
Got 8 ribs (slingshot) instead of your "old five rib" machine & got
alum angle braces on all of them.
I may put the back struts on just to keep the wings from twisting.
Just wondered how it feels the first time, it's hard to make it go
into a spin anyway, seems like you got to
keep every thing cross controlled to even get it to turn once?

My boo boo. I related the photos you posted of Fergy ribs to the ribs and
wing panels on your aircraft.
To spin my Kolbs, I pull the nose up high with power at idle, full left or
right rudder, and full aft stick just as it stalls. Hold it until you are
ready to recover. Usually, relaxing the controls will recover the aircraft.
My original FS would only spin one half turn at idle. It would recover with
the controls crossed up and locked. During some experimentation doing
engine off aerobatics, I did a spin. The little FS spun up like a top.
The MKIII loses a lot more altitude than the FS. That was quite a surprise
first time I spun it.
One will have to work at getting a Kolb into an unintentional spin.
However, I am sure there are those out there that can probably get
themselves into one.

It spins pretty good, fairly controllable. Losses about 500 ft or
less per turn.
All it takes to stop is take your foot off the left rudder.
