Yes, I meant Vmca. Was a little loaded when I wrote that.
The pilot gets sore in the leg from standing on the rudder and slowing down to the point he loses directional control. I was the "movable balast" along with several sand bags in the back to make for heavy aft cg. If we were to go into a spin I was to grab a bag or two and try to jump in the copilots lap to hopefully get the nose down. Glad we did not have to see if that would work.
