Or you could try a little 1/2"baffle" attached to the exhaust top to deflect the gases down. (just like a water-hose, when putting finger at the tip,) Wouldn't need much.

or a small half moon filed into the bottom of the exhaust end, will have a similar effect.

Every other option is "after the event" procedure.

If you HAVE to set down, does it make any difference if the Name is "strip, fire-break or access road.

safety first, lets have a few more of them, does having a "windsock" on any patch of dirt break any rules ?.

The insurance bureaucrats have to sit at their office finding ways to stop us getting money out of their company.

Like the HummelBird the occupant section is made a little stronger to safeguard the important bits. & the rest to come apart to remove inertia.

I saw a video on "missing rivets" It could have been the Zenith planes, but didn't take much notice of the make. So I googled "missing rivets" & it came with what I posted.

Their answer was to replace some of the pull rivets with solid.

The rivets were only in the one area being affected, & Hummel aircraft forums have said beware of pull rivets working with vibration.

I have noted that some larger pull rivets (not on my aircraft) didn't quite pull tight enough, and could turn in their hole. ( when drilling out pull rivets they sometimes spin with your drill-bit).

spacesailor

I want to say !.

A big nappie

there said it.

But is that stain on alloy or paint ?. could try a small baffle/ deflector to throw the exhaust gas off the surface.

spacesailor

Are you "hard riveting" or pull rivets ?

I saw something about the "pull-rivets" working & falling out near the tail end of the fuselage.

Zenith Aircraft Co, site, " Nevertheless, I feel impelled to warn some experimental designers that the shear values given by the blind rivet manufacturers in catalogues are to be looked at with some common sense as well. The manufacturer is not a liar, but he does present his product in the best possible way. For example, when they make tests they use very thin sheets so that the stem is long enough to fill the rivet (see figure 4), which is the reason why the individual shear strength is higher than an aircraft solid rivet (the steel stem participates). But on our aircraft, this is relatively seldom the case. As a rule of thumb, a reliable shear value should be 1/2 the catalog specification. But again, the designer should make tests. (Just as an example, when I do blind rivet tests, I knock the stem out before the test, just to be on the safe side!) " (article by "Riveted Joints By Chris Heintz, P. Eng)

?, How to submit,

Thought of putting the "Shiny Hummel bird" in but couldn't find my way to do it. (favorite planes)

"Even with cars, it is cheaper to replace with new than keep forking out for expensive mechanics and spare parts."

Another Government interference,

BackYard mechanics, under fire. Modified vehicles under scrutiny, and only certain mods allowed.

When my Pajero Mass Air Flow Sensor, failed, my favorite B,Y, mechanic took a couple of minutes to find the problem, And a day to replace with a cheaper (than Mitsi) part.

Touch a new car's anatomy & kiss away your so-called (expensive) warranty.

\\\\\not all are happy with Diesels !.

I met a farmer (between Dubbo & Burk ) that absolutely hates them, Only because, if he has a problem with a ( brand spanking new) diesel machine, it take's three days for the mechanic to get to him & look at the problem,

Then goes back to the shop (Dealer ) & report problem, second mechanic arrives ( at least one week later ) with a Few tools to remove offending part, & returns home.

Two Three even four weeks later. ! . third mechanic arrives with (supposedly ) the new part. and repairs said machine . ( has known wrong part more than once )

All in the heat of his harvest.

Now, new machine arrives, He rings neighbour to come & remove that new diesel, & replace it with an OLD second-hand Holden V8.

Never seen so many shiny diesels left in paddocks anywhere !.

At $5 million a crop a couple of weeks waiting can be disastrous.

Is this a "for sale" aircraft section,

Or

"My favorite aircraft"

Just a mo, I read this & assumed the writer was correct.

" "Every engine must be totally disassembled and the wear and tear of each part evaluated separately" (Source: Sapling.com)".

Each part"evaluated" If spending tens of thousands of dollars. I would expect NEW parts. Not IT'LL be allright,!.

I don't know "Sapling . com".

"By now there should not be a sheep, goat, or cow which is non-compliant."

There's a growing band of "Huntsmen" who are making a living (subsistence), out west, off the grow number of "Farrel" cattle, the aren't economically viable, ( possibly because of the Bureaucacy).

As well as the Pigs,Goats, & Roo's. They (ferrels) are destroying the meager grazing land, just like the camels did or do out back, and horses on the alpine slopes.

spacesailor

Doesn't make sense to me. The cost of labour to strip an engine, AND NOT replace All wearable parts, is a waiting game, as it Will need those parts replaced at a later date. !.

O K if owner is doing the work & not counting their hours of labour.

Who on the old Ford / Holden motor's never put new "valve stem seals" in their motor as the old ones never gave trouble,?.

Building your first kit aircraft IS a learning process, & will show (hopefully) that the beginning is Not as neat & tidy as the last rivet driven,!.

The OLD venturi depicted only needs a T piece near the hull-skin to connect your Peee-tube to, An off-tap could be prudent, (just in case of excess suction). (please don't put venturi on back to front( may cause "blow-back))

BUT

If worried use RED750 's bag,

All come in kits.

You mean poor installation work,

I expect most (average ) flyer's could manage to put an adapted venturi type Peee exit to dispose of any wast.

unless you want to keep it for the garden, LoL

AND Again the OLD is comparable with the new.

1940's McCulloch motor of 3 litre, 72 hp @ 4100 rpm, weight 85 lb  8.0 to 1 compression ratio.

" This VW type engine is the perfect example of what "simplicity" gets you. Low power, poor economy, poor tbo and heavy weights."

Well it is a 1930 design !

LIGHT weight,

Great power to weight,

61 U.S. MPG = 3.86 Liters per 100 km, at 100 mph

Runs forever,

Remove the "Flywheel.

YES

But I,ve been offered lead acid batteries at half the retail rate.

So why the Big markup on the "mobility scooter" batteries, ?.

$ 185 the cheapest mobility battery, compered to your $145 for a golf-buggy battery, the same size AND Brand.

spacesailor

I'll be checking that site too, as I would prefers a light-weight battery to a very heavy lump.

spacesailor

THANKS.

onetrack,

Outstanding work, The "Spiders did to make that "KIT-HANGER".

It would be nice to see Big Birds of that magnitude in the skies again, like "Bondies Blimps".

My Mother watched the R100 fly overhead, & always praised it as spectacular.

OK.

come on over & I'll let you have a try on the Hummel Bird. LoL
