Default take-off distance.....factors?

Since no-one has mentioned it.....are you planning a climb prop or C/S?
If not, you are not getting a ton of hp from your engine in the crucial first 10 seconds or so.
Loading to gross, on a hot, calm day may put you outside your comfort zone, but it can certainly exceed the aircraft's ability....it would be a shame to be grounded on those nice days.

Default Runway size

It may also be hard to purchase insurance if based at a runway like that!

I second that notion.

RV's are wonderfully manueverable airplanes that inspire flying confidence in all of us, but to land - day in and day out - on a 1000' strip would require perfect conditions and perfect piloting EVERY time. That's a bit much to ask for.

Default aim point considerations

Suggest you consider moving your aiming point, wherever you base your aircraft, and give yourself more options.

I'm a low time pilot, and aimed at the numbers because that's what I learned. A high time pilot pointed out that means my error margin was +5000 feet, and -0. This great stick and rudder pilot used the visual touchdown markers, with plenty of room to slow without braking before turning off the runway.

I now aim for the touchdown markers, which gives me much more room for error, and aligns me with the VASI. Nice how that worked out...

With respect to the video of the RV-6 touchdown in the pine forest on a very short grass strip, the audio is worth a listen:

"No F****** S***
Please never %^%^&&*@ do this again. D-you hear me?"

Default C/S prop effect on landing distance

I was thinking the same thing, although I was thinking of the drag benefits of the constant speed prop in fine pitch during the landing phase. No one has mentioned it, but it has been reported that a lightly loaded RV will tend to float in ground effect with a fixed pitch prop with the engine at idle. Maybe the -7 floats less than a -9, but it is something to consider.

For me, I'd say get it flying first, base it at a longer runway, become proficient at taking off and landing, and THEN make the decision to build your own runway. I'd want it at least 2000 feet with unobstructed approaches on each end.

Congratulations! At 5:35 your camera is almost perfectly aligned with the two orange cones on your airfield. Not sure if that was intentional, but when I saw them, I thought, "What was that?"

I was planning on a constant speed prop with a 180 hp engine. I was figuring if I missed my landing point I would just throttle up and go around. The video has me a little confused. If that's a 1000 foot strip and he touches down at the beginning, why does it take him 1000 feet to stop? It seems like he was just trying to scare his passenger.

Any sort of rough surface is going to greatly reduce braking ability and therefore increase stopping distance. It looked to me like that surface was very rough. 3-4 knots too fast along with any tailwind could easily have you eat up that much grass, I would think.
