Default ''Perfect" Landings: The Search Continues in my RV-7A

Another unique view of landings from under the plane.
I took in everyone's advice from my last posting of my landings video, and tried to raise the bar (and the nose-wheel too!)

[I polished up the belly even more, I hope Webb notices again ]

Default Nose gear

Just courious judging by the fore and aft oscillations of the nose gear during roll out am I correct that you have not gone with one of the modified nose wheel bearing mods?

Great Video, thanks for sharing.

I am by no means an expert, and your landings look great. It looks to me that your touchdown speed is a bit too fast. You should be holding it off longer. I remember (long ago) doing a landing and my instructor pulling back on the stick and back up we go. "Too fast" he would bark. You always remember those.

Here's a video I took which I have in another thread about shakey wheelpants with 3 of my landings in it. My video skills are not as good as yours though.

Fast forward to 2:21 for landings.

No expert here, either, but I concur. 65 kts over the fence and hold that nosewheel off until you run out of elevator authority and it *has* to come down (at a very slow speed).

And...are those flaps fully deployed? They don't appear to be to me, but it might be an illusion because of the wide-angle camera.

Don't know that I've ever looked, but I can probably tell you exactly by looking at the datalogs from the EFIS (compare airspeed to pitch angle). Stand by...

That was a fun video to watch. Nicely edited with voice added in.
Your landings look great by the way. I think all the A model RV's shake a bit when the nose touches... bearing mod or not. It is just really springy.
Keep the stick coming back until it comes down on it's own. You looked good out there !

Great Video, thanks for sharing.
The fork and bearing are vans 2nd gen. The only mod made to that was to drill 2 small holes through the fork into the bearing to stake them with roll pins. It doesn't have the grove or beringer setup if that's what you were asking.

Glad you enjoyed the video!

Well, I thought that would be easy, but the data is pretty noisy for pitch angle, and they're nice small values so it makes it worse, but...looks like it is coming down at around 40 knots indicated or so.

In the beginning, when first learning to fly the plane, I would come down final at 90mph. As I gain experience I brought that speed down to 80mph. I go by MPH rather than KTS because the AS indicator has its larger outer ring in MPH.

That was really an interesting video you made of the shake. Fun to see that someone else did some under-the-wing videoing too. Those wheels Really do shake though, even after the balancing. I couldn't help but go back to my video to see if mine do that too and I'd just never noticed.
