I am prejudice to the Sportsman stall cuffs, They are stc'd to Cessna but some were also designed for Piper and not stc'd (to my knowledge) so if the airfoil is the same to one of those or very similar they may work.
Another option is to get with a good CFI and really explore the low speed handling of the Mooney so that you can get the most out of it. I
I appreciate your thought on this, but the numbers I came up with are a little lower. There were about 7000 180 & 200 HP Mooneys made, about 5000 of those are short body Cs & Es. 1% of that is 50-70 units. That would be the number who would find value in a soft stall and speed reduction on landing, and that could pay for the cost involved in development and production. My initial thinking on this was the value wasn't so much in a speed reduction, but a forgiveness of the stall that allows you to get as slow as possible and hang there while you land.Offer a mod to get 2-3kts - you'll sell thousands.
STOL kit? I think there's a guy or two up in alaska who might be interested... but I think they want bigger tires over slower approaches.
How much of that is due to the need for better, faster, control input in the flair because of the greater drag / faster deceleration with full flaps? A PA -18 three points easily with partial flap deployment, even for someone who doesn’t regularly fly the Super Cub. With full flaps, timing is everything.I find my bird much easier to land smoothly with 1/2-2/3 flaps or no flaps than full flaps.
