Aero Commander bought the Intermountain, originally Callair, A9-B and called it the Quail. All were crop dusters or glider tow. They were tube and fabric with wood spar, unless Intermountain changed that. Aero Commander made very few before shelving the program.
It was the best flying crop duster I ever flew. With ribs in all controls, it handled like it had hydraulics, even with a full load. It wouldn't haul as much as a Pawnee, even with the same engine and wing area.
Many Pawnee operators avoided the Callair because it would drop the inside wing if you pushed it too hard in the steep turn. The down wing just dropped like a spin. I didn't think it was a full spin because just a tap on the top rudder brought the bottom wing right back up. Very scary, however. It definitely caused you to level the wing and abort the spray run.
