Your looking at the wrong video
In one of the videos you see the nosewheel shimmy back and forth as the airplane accelerates. It is this motion which I think needs to be damped.
Although the video is interesting, it has nothing to do with real "A" model operation. It shows slowly going to a high speed taxi. This is not a recommended thing to do with a RV and most other small planes. RV are designed to fly and not drive.
Check out the videos that I made. I show both paved and grass takeoff and landing. No high speed taxi.

How to take off:
1.
Line up to runway heading.
2.
Hold stick full back.
3. Apply
full power (note that planes nose raises some, less weight on front wheel)
4. When nose wheel leaves ground (about 3 seconds latter), ease back on stick, but
keep nose off ground.
5.
Leave ground and don't return until your ready to land.
How to land:
1.
Line up to runway heading. (Your on final)
2.
Maintain speed at 1.3 x stall.
3.
Pull back on stick and reduce power as you enter ground effect.
4. Keep the
nose wheel off the ground.
5. Let the plane settle on the
MAIN wheels only.
6.
Hold the nose up (but not high) and don't use brakes unless necessary.
7. Keep pulling the
stick back as you slow down.
8. When the stick is almost all the way back, it is time to
lower the nose to the ground by easing forward on the stick. Let the wheel touch lightly.
9.
Slow to taxi speed (5 to 10 mph).
You need to
practice the above to be good at it.
If you miss some of the above steps your plane might not last as long and you made need to replace more then your nose wheel.
I am all for coming up with a better wheel/gear, but not if it compromises the flying characteristic of my plane. After all I built it to fly not drive down the runway.
