What is the short field landing distance for the 7A on short grass fields, with no obstacles on approach ?

I have quite a bit of short field experience in my 6A, not any difference between it and a 7A to speak of. I have a 180 HP with a three bladed Catto prop and when I drag the airplane in at 65 MPH indicated (which is nose-up attitude) I barely can stop in under 500 -600 feet on pavement and braking fairly hard.
A friend has a grass strip, 2000 feet long with one approach over short trees and tall trees at the other end. Dragging it in as slow as I dare, I can't touch down for almost 700 feet and brake hard and still end up very near the tall trees on the other end....kinda scary sometimes. Granted, I could probably use a slower, closer to stall airspeed and do better. My advice to you is to be sure and practise a lot before going in to short grass strips, especially if there is no overrun as in this case. It's hard to attain Van's numbers IMHO.
Regards,
They're better pilots than me.They both made two or three landings and the part that impressed me was when I walked out on the strip and found the touchdown marks. All of them were within a few feet of one another and none was more than about 25' from the threshold. Very accurate flying.

The fixed pitch prop is not helping the situation.
The difference being a CS prop. When the throttle closes, the prop becomes a big speed brake. .

I do a 1k' strip quite often in the Super 8 with tail wind. If I come in steep and slow, flare and crash in 3 point, Im good for the half field turn off. Right after gear squat and crash, its stick fwd, tail up way past horizontal, and hard on the brakes to stop. When I flare there is nothing but a buffet and crash landing. I drop 2', gear squats, crash land and I know I've done good. Tail up to get weight on mains and cg fwd to apply hard brakes. Tail is still up till almost stopped, then add power briefly to set tail down nicely.
If I come in shallow same speed, flare and grease, Im 3/4 down field and have added 200' to my rollout.
I dont know Vans technique, but this is mine and its not for the novice. It can be easily practiced on your long pavement first.
My 2 cents.
