Nev is right - it's built like a brick sh*thouse, the thickness of some of those parts is impressive.

250m is pocket change to some venture capital firms, but would buy a fair chunk of the ongoing revenue if their Arc reaction motor becomes a reality. I have to laugh at their Slipstream Elite design, is it pure coincidence that the "grille" looks like the Bugatti Veyron and the body shape like early 70s muscle cars?

The fact that there are no intakes for the engines, but more seriously the CG must be about a metre behind the TE, are giveaways...

Looks like a Photoshop job to me. Reversed Gripen perhaps.

Very good point.

I thought NCC-1701 was the number of the USS Enterprise.

Hmm - just noticed the runway numbers on the aircraft carrier. That's a bit odd (presumably they just steam into the wind no matter what compass direction it's coming from!)

Nope - going to just use a good quality normal hose clamp on that one (bolt style, EFI type if I can get it in that size). Two evenings wasted on it is enough.

Well, I think it's going to be Nev' s solution, another type of clamp for that 1 elbow. Not sure why Rotax didn't just extend the elbow so you had clear space to put the hose on, everyone has to do this every 5 years so seems like a design flaw to me.

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.

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
