That's exactly how it's done and that's the way the transition folks will teach you. It's a taxi gear, not a landing gear.

I have almost 1300TT on my RV6A and have never had the nose gear leg or fork modified as per the Van's service bulletin. If you fly it correctly you won't have a problem. Also, I modified the nose gear wheel bearing setup so the axle bolt doesn't bend and bind up the bearings causing the wheel to skid and tuck the gear. A precision spacer between the inner races to set the bearing clearance works like a champ.

Allan at Anti Splat Aero has the whole nose gear thing figured out and makes a nice safety kit for it. I installed one on my airplane and the new fairing is slightly tapered to accommodate the brace.

The nosewheel on any airplane is only there to keep the prop out of the dirt. Young Grumman driver have problems landing on the nosewheel.

I'm building some RV-8 parts in my garage.* I know there are many other BT'ers who are. Speak up!

I know there are RV forums online, but BT is better than any of them for at least two reasons: real names and photo hosting. So, even if we only have one thread, it might be worth BT RV builders coming out for some mutual support and photo sharing.

Here's mine:

I'm working on the left (first) wing, finished laying out the skeleton and skins, procrastinating on the tanks. QB fuse ordered, won't be here till some time between Thanksgiving and Christmas :bugeye:

. People tell me SB wings and QB fuselage is backwards, but it's what I've done.

Hurry up Stu

*I tell people I'm building parts so I don't have to estimate when the airplane will be finished. And if I quit before it flies, I'll just say I finished all of the parts I intended to build!

Bad story from NZ. Second RV-7 structural failure this year. Anyone have an insight as to what’s going on? https://www.avweb.com/avwebflash/news/Wing-Loss-Possible-In-RV-Crash-230139-1.html

Awful and scary. Reminds me of the wonderful guy Tony Kelly -7 horrible in flight breakup. I seriously considered a chute for the 6 after Tony’s crash.

I'm no engineer, but it seems that an in flight breakup is caused by a poor design, poor construction, poor piloting, or a combination. Makes me want to doublecheck some rivets.....

Although anything is possible, the anecdotal evidence to this point in the Australian crash doesn't support your supposition as the accident pilot and his aircraft were well known down under and to a lesser degree to the RV community. In any event, the actual cause has yet to be determined or released.

I seriously doubt design. There are thousands of variants that do not fall part. Just like V-Tails, a few having failures suggests the real reason will become obvious.

For example, someone has been aerobatting the hell out of it and has regularly exceeded limits, or maybe some bolts have been left out.

The NEW ZEALAND CAA investigation people are really thorough. So I would hope we one day know whats going on.

The EAA produces "The Green Dot Podcast," and in the September 2017 edition they featured Richard VanGrunsven.....RV.

It's REALLY interesting as he talks of his early life, the different RV designs as they evolved, etc.

He's 78 years old, an engineer by training, and he plans to keep working "as long as I can." Van's Aircraft has 65 employees, and he says there are 9600+ RV's flying. Dick also serves on the EAA Board of Directors.

Here's the 30-minute Podcast: http://inspire.eaa.org/2017/09/06/eaas- ... ngrunsven/

RUMOUR ALERT

This is by no means factual, but I have heard from local RV owners in Brisbane that this plane was vinyl wrapped over a zinc chromate surface.........which had experienced adhesion issues.

Pure speculation surrounds the concept of a massive lift dump due to departing wrap or flight controls.....or....

So anyone considering this might want to ensure the surface is compatible and adhesion is good and any joints overlap in the right places etc.

Vinyl wrap like what is put on cars?

Many planes are partially or completely wrapped. It weighs less and costs less than paint, it’s quite durable, and the designs and colors are infinite....

I had part of my RV-6 tail wrapped...

That's looks nice. Assuming that it is installed properly what is the down side?
