RV-6A noseover video...

Looks like an anti splat in this image, doesn't look like it helps the outcome any...

Yep, that looks like the way an antisplat is made with the little fork on the end.

I think I disagree with statement that it didn't work or help There may have been a violent crash when the initial bending occurred without the brace.

Obvously the gear leg fairing is missing in the image. Either not installed or broke off.

Food for thought

It's not the Anti-Splat gear mod. The ASA attaches at the mid point of the stiffener; the frame grab appears to show that the "stiffener" has one attach point near the cowling. Maybe it is a vibration dampener?

And in this image / perspective it does look like the ASA mod... Maybe two different parts? Or what was left of the fairing?

I get the impression from many posts over the last couple of years that many folks think that the AS leg stiffener is going to solve all their problems on A models. It isn't. If you bent the leg like this and land on even slightly rough grass, almost certainly the airplane will flip.

If you hit a big rodent hole even at a moderate taxi speed, you're also likely to severely damage the support structure or flip too.

The AS device will give you a bit more margin in certain scenarios but ultimately if you put a couple thousand pounds of force backwards on the leg, it's going to bend at the engine mount support anyway.

I also see posts where people believe holding the stick full aft will have any useful effect below 20 knots with no propwash over the elevator. While it's good technique to do so, you won't even take 50 pounds off the nose gear. That's not going to save you either if you hit a hole or asphalt ledge of some sort.

Even with the best technique, if you fly off grass long enough, you could have a bad day hitting something higher than the tire to leg end clearance.

[ed. I agree! If the technique is off, no hardware is going to keep you right side up. Here's an AS from a noseover event (not the one discussed here). Just making the point that technique is the #1 determining aspect of staying upright: v/r,dr

I wonder if Antisplat can confirm with the tail number.

And being aware of where the CG is at the end of a flight is extremely important, too.

First post on any forum ever....Hope it works and that I do not breach any VAF rules.
At the beginning of building my RV9A I had absolutely no idea the nose gear could fold up, ending in a flip over. Once I found out I started to read all available accident reports, videos on Utube and discussions on VAF.
Over the years it has brought me from a happy builder, over despair and all kind of plans to mitigate the risk. The more I studied the subject the more convinced I was that I - with my moderate flying skills - will end up inverted.

Well much to my surprise it has not happened - yet.....I hope I am not committing hubris though.

One of the very first things i did was adding a camera under the wing to see all 3 wheels, in order trying to describe the dynamics involved in the nose wheel oscillating. This turned out to be too complicated for me, but I did develop a sort confidence in the design, and certainly found a number of bad habits and things not to do.

I have only operated on relatively even and level surfaces. I am still convinced that if the NW falls into a pothole or meet an obstacle higher than a couple of inch the gear will dig in.

As other and new builders of A models may be going through the same despair as I did.. I thought I would make my video available for all

It comes with a warning: It is extremely boring and have no entertainment value at all, but if it provides peace of mind for anyone then its worth the 18 min of NW oscillation.

What surprised me the most is the last sequence of the video, where the plane actually lift of - just a few inches - and then lands on the NW without me noticing it - until second landing.

So it seems Scott was right in his reply 8 years ago: "Fly with confidence"
......And perhaps the design is better than its reputation?

I'd love to watch the video, but the link doesn't work. Do you still have your RV-9? Your signature suggests you donated it?
