Be interesting to see how you do that canopy since the rear fuse is flat sided and not rounded.

 

That can be a problem with information obtained from the 'Net. 

 

Sacrilege!

Heathen!  

Sounds good, but don't forget that it will not allow for fatigue, which is one of the expected fail points of a welded joint.

 

Somebody else mentioned glued joints. Not easy with aluminium, but I did one years ago and it knocked around for ages, never did give way, but I don't know where it is now.

 

I cleaned all the faying surfaces, then used a scotch brite pad, coated with epoxy glue, to give a final cleaning and spread glue to stop oxidisation.

 

The best common stuff I have found is "No More Nails", "Liquid Nails" whatever your local brand is, I actually checked a joint I did about 4 years ago the other day, amazingly solid.

I went to a thread about an accident to find myself in the midst of a discussion about  Japanese immigration. I'm only interested in coming to a recreationalflying forum for recreational flying discussions. It has been in a downward spiral for some time so relying on subscriptions and pushing donations will only add to the downwards spiral. Usual recovery from a spiral dive - unload, power off, roll level and pull out.

 

It is indeed a recreational flying forum, but thank goodness people here also have lives and other interests.

Just how many times over the years can you 'only' talk about take-offs, stalls or aerobatics, and just how many replies specific to those titles can there be ... well I'll answer you, not many.

Threads would be short on replies, as well as few started in the first place, if it was 100% pure Rec Fly.

My experience in forums is that most of the nonsense you refer to starts well after the thread's topic has been suitably attended to/answered by Members, and that there is really nothing more to add than to have a bit of fun, or expand on some point someone has made in the replies, usually on page 2 or further. 

So I think your "pure" forum requirements could only come at a cost of the forum collapsing for lack of traffic and boredom.

Ian, what money are you looking at each year to service us with the forum?

As Onetrack mentions, those rods are pretty much rubbish, they are as mentioned, like aluminium soldering.

Aluminium welding is fine if a process is followed, re; re-heat treatment, or enough additional area that the softened area meets the strength of the original material. 

Motocross bikes have been using thin gage aluminium welding for decades now under severe punishment, and have lasted just fine, besides all the dire internet predictions. But they go through a re-heat treatment process that simply isn't available easily to the homebuilder, and then there's repairing damage later ...

You could consider gluing, but that's a bit of a process too, also involving a big  oven, Google Lotus Elise chassis development.

As pain in the azz as it is, there's sound practical reasons that we still rivet, and I would for one who drilled another 2000 rivet holes just yesterday, like to find that magic replacement, and I have looked.

This guy is doing a 30 day Zenith 750 challenge, maybe some tips/hints, or just motivation for you ...

A team of 24 firefighters from the Metropolitan Fire Brigade sprayed the aircraft with foam hose lines as a precaution while MFB Rescue Operators worked to free the pilot. Evidence Eradication Team strikes again

 

The Bristell has it's fuel tanks unusually far out on the wings due to having large baggage compartments in the wings close to the cabin, where I see the white foam is where the tanks are

Ok, so lots of ES attend, they hear it's a plane crash, maybe don't know what size and how many people involved, but what I can't understand is why so many are still there long after the peak danger period has been dealt with.

Eh, what happened to my video ...

Here's the sides being cut.

Even though they actually have a bit of a rollbar, there is negative 'broomstick' head clearance in a Bristell, so it's useless anyway.. 

Another plane crash that apparently needs all of emergency services to attend, I count 22 men in one picture, likely more out of shot, and that's after they had extracted the guy.

Starting on the front fuselage, cut some sides today and checked on bracing fitment.

I'm using titanium(IV) oxide for sealant because titanium is strong and light ..

Sometimes uneducated people call it "white paint".

I see your son is a beer connoisseur ?

 

What do you expect, there was beer in the bloodstream at time of conception ....

Oh that reminds me, the other day I found this old picture of me when I was young ...

Already available - in "adult" shops.

 

Yup, this thread is apparently about aircraft I just found out, dang narn it!

It's a pity that with the hundreds of users that come here these are the only replies to help the site:

 

Many People no doubt appreciate it, but it's not their lives, so look after yourself first, stop stressing over them, go the cheaper Z route, do the banner advertising, you know some of us will donate, and all will be good.

Bex. Please.

 

This is an aviation forum!

 

"Is ice on your wing water"?

Quote/"Does a fly do a half loop or a half roll to land on the ceiling? "

 

When I was a young impressionable bloke, that very question caused a group of us to spend an entire long weekend  consuming excessive amounts of alcoholic voice lubricants, in order to solve this important aviation conundrum. We never did come up with the answer.

 

Next time try: Is ice, water?

Another good one: Is milk, a liquid?

I haven't gone quiet, I have been spending a number of hours sorting out the wings and some other details.

I did get a chance today to make up 4 gussets to aid in the connection of the front fuse to the rear fuse, it will all make sense later on ...

Bex is right. 

 

Which leads to the obvious conclusion that you may be the second smartest guy in the forum.

And right now it isn't very measurable

 

Yeah it is, and it's simple, up to 600kgs = 45 knot stall.

 

As others have said the current rules will leave you scratching your head if you are thinking in terms of energy at stall speed as 300kg doing 45knts is nothing like the energy 600kg doing 45knts yet both exist within the current RAAus administered area of recreational aviation.

 

I wasn't suggesting they use a kinetic formula, I was merely pointing out how the 45 knot rule came to be.

If you buy a 400kgs carbon fiber whiz bang, congratulations, you will meet the 45 knots and go faster with less wing than the guy with the 550kg craft, that's what you get for your money.

Clearly speed ain't everything to everyone, but many consider safety a good thing, even when it needs to be enforced, and that's what the 45 knots is aimed at. 

Site seems fine to me. Don't see what the fuss is about. A donation of $50 / year for those who want the site and can afford it seems reasonable. 

 

Well I'm in as soon as this is all cleared up.

The stall speed increase required is around 2-3 kts

 

Why, there's 140 LSA craft that meet it now.

Not being combative, I honestly want to know your foundation for my own education.

 

2. Preferably separate since it's not aviation related.

 

I think the simple solution is that it doesn't appear in "What's New", if that's possible.

Off Topic followers merely have to get there manually, fine by me.
