I too mostly fly by feel. Recently I flew out of my field with winds southerly, which means big trees to clear on departure.
I took off, 15 flaps, full fuel, I see those trees coming at me. Over the trees I glance at my airspeed and I’m at 38 knots.
I didn’t realize how much I was pulling.
Today I recalibrated my audio stall warning and did some stall practice at altitude. Tried to duplicate conditions 3000 agl. Full power stall was down in the 20s Indicated and even then it was with a gentle event.
