One way this and other tricky jobs on aircraft can be done is with lock wire. Open the clamp in a vise, lock wire open, slide into position, cut lock wire. Workes on P clamps as well.

That's a great idea.  The pliers actually ratchet closed to lock open the spring,  so I'll try that.

Hey folks, looking for tips and tricks to get the spring clamp on the no. 3 cylinder top coolant elbow.

This bastard is under the carb manifold and there's no room for the spring pliers (bent elbow type) to fit. The electrical box thingy is also in the way.

I don't really want to disassemble the stuff at the top of the engine to get at this - is there an easier way??

Thanks,  Marty

If you want speed out of a smaller motor,  go motorbike. 

I've seen many crashes at the R/C airfield, I reckon the little bloke would rather be on the controls!

Party balloon?  Maybe the little guy on the box is farting into it.

Classic example of jumping to conclusions on insufficient evidence.

Due to a very superficial similarity to another drawing, this person has concluded that a civilisation which has left no evidence whatsoever of powered tools has actually invented x-ray.

This is tinfoil hat stuff.

Some other space cadets think it's some kind of sand blaster (not a snake holding science experiment) - as the original carving looks quite different to the cartoon pictured.  

My guess -  it's some dude proud of the massive marrow/zucchini/eggplant he's grown.

The truth is that we have no idea whether this drawing was based on something in reality, something that a priest dreamed up about the afterlife, or just Egyptian science fiction.  It's like someone in the future reading Asimov and concluding that humanoid robots were widespread in the mid 20th century.

I don't see how.  It would be too expensive to ship it out from the US for a couple of airshows.

Hoover - Skyrace 1994 and 1995 at Valley Field. Yep, I was there too. Unbelievable it was watching him do his thing. Man, the noise when he killed both engines! Damn thing sounded like an inbound SCUD missile. I seem to recall too, some Australian announcer from USA. Gordon Bowman-Jones, that's it. Man he was annoying with his bullshit. I can still hear his voice.

"Here comes Bob on the down line - both engines totally dead!"    Ah no dude, one's actually still running on this pass.

Valley Field was a great viewing venue - just like RENO - with the mountains in the background. Been there too.

And sadly - upon arriving back at Launy airport to come home on Monday, we saw smoke rising and a few T-28's on downwind to land, maybe Judy in the lead? Some asshat showpony did a roll on takeoff and didn't make it. Airport passengers saw it happen and were shocked. Some years later, I spied the rudder of that ship hanging on the wall at the Launy model aircraft club.

 

Your memory is better than mine!  Now you mention it I remember that T-28 crash.

Not long after that we had one of the US carriers come into Hobart, and I remember talking to some pilots (sorry, "naval aviators") in a bar one night.  They were like "Bob HOOVER flew here?  Where's the strip?  How do we get there?" I think a bunch of them hired a car and drove up there just to do a pilgrimage to the site where Hoover flew.  I have an inkling that Hoover at that point wasn't allowed to fly in the US and Australia had given him a licence, so that may have added to the attraction.

I ended up getting an Aeroflow manifold. My attempt at tapping my own was not entirely successful. 

Also have some Mikuni jets on order for restrictors.

Skyrace Tasmania.

Also Chris Sperou landed his Pitts Special upside down,  but not sure whether that was the same year - I went a couple of times. 

I saw Hoover do that in an Aero Commander about 20 years ago. 

My lovely wife bought me a Tamiya 1:48 scale Mk 1 Spitfire for my birthday earlier this year.  Unfortunately I don't have any paints so until I source those, she stays in the box.

Now that wheeled wing dolly is a good looking beast.  I'm copying that.

Check the BRS website.  When I was considering putting one on the recommended cover was light polycarb or similar, with a circle scored in it and radiuses scored from the centre out in 45 degree increments.  

The intention being that if the rocket fired it'd break through the scored polycarb and those radii would open up like a flower.

I agree with the others re strut mounts and bolt types.  Not a huge investment to replace all the essential (wing-holding-on and primary control) bolts with proper AN ones, and you'll get peace of mind.  Definitely need to take the paint off those strut mounts and check for cracks though.

What is the part with the crack in the side where you asked if a doubler should be used?  If at all important I would fabricate a new one - doesn't look very big but the rolled edge may give you trouble. 

Vertical fin & HS on both of those resemble the C17 Globemaster.

Hi all,

Interested in where to source a pitot head in Australia.  The CH701 plans just show the single (facing airflow) tube under the wing, but it seems common that people use the double tube where static is on the same probe either concentric or parallel.

Aircraft Spruce have them for about $40 US - https://www.aircraftspruce.com/catalog/inpages/pitot15144.php - but it's the postage that kills it!

If unavailable in Aus, has anyone built one?  I'm guessing the static tube has the forward end closed but small holes drilled into the side - how many, what size?  etc.

Do you use 1/4" nylon or plastic tube?

All advice welcome.

Cheers, Marty

No! No it's not. And we're full.

Thought it was suspicious that Google only found that image on Facebook and YouTube,  no reputable sites.

 Maybe Tasmania is not as bad as the others. Nev

So true

It doesn't surprise me that Phantoms etc can fly with wings folded - but imagine the landing speed...

That's not correct. There's not much difference between the Two. I've had a Groundspeed of 700 knots in a B727. the Planned TAS  in still air is 480 Kts but you'll never see that figure on the Airspeed indicator.  With the Jet stream there's a risk of turbulence at the boundaries. Nev

Google's most popular answer must be wrong then.

If it was a 727, I believe their cruise speed was in the order of 40 knots higher than 737's to start with.

I think there's a fairly big thread over in Social Australia about this.

For me Occam's Razor informs.  What's more likely - aliens that have the technology to travel thousands of light years yet can't drive properly in Earth's atmosphere and only appear to Daily Mail readers, or existing phenomena - weather balloons, auroras, ball lightning, light patterns, electronic glitches and hoaxes?

As for US congress - half of them seriously believe Trump is their best hope, so not a lot of logic going on in those heads.

You're limited with some aircraft for sight tubes.  On mine for instance the wing roots reduce in size close to the cabin, so there's no way to have a full height sight tube.
