Just thinking back to my teenage years Mark - that cover looks like it needs a subwoofer in it 😁

Thanks Rob, that's very handy. I wondered what that nipple on the oil tank is, now I know - overflow!

I bought some oil cooler fittings from a local performance auto store (ended up going with Aeroflow fittings) and thanks to research done by @skippydiesel I went with Gates 8GTH half inch hose, stocked by the local Hardy Spicer ($67 inc GST for 2m, if anyone's looking at prices). The Aeroflow fittings weren't cheap but the 135 and 45 degree angles on them means a better run for the oil lines. Photos show temporary fitting - still waiting on some ally M22x1.5 nuts I've ordered, I'm in no rush so ordered from China. Will still probably have to cut them down to fit them under the oil cooler mounting. Hoses can disconnect quite easily. Unfortunately I'm going to have to take the knife to the cowl (again - it's going to have more blisters than a teenager with acne) - the starboard side of the radiator is pressed hard against it and there's no wriggle room. Hoping to do that tomorrow. I have a spare carbon fibre blister as I made 2 when I only needed 1 for the throttle clearance.

Lovely watching those big slow models. Too often r/c models are too quick/agile and it doesn't look like a real aircraft.

That's very generous, you have to let me pay postage! Will PM.

Hey folks, Wondering what people use for this. Standard from Flood's or is there an auto equivalent for 1/10th the price? As far as I can work out from the Installation manual, Rotax specifies a container that may have up to half a litre of overflow (so 800ml or 1L size?), hose from the expansion tank going to the bottom, and a 3mm hole in the top vented down through the cowl. Level of coolant in the overflow tank to sit no lower than 250mm below the expansion tank. Are my assumptions correct there and what sort of bottle do you use? Thanks!

That doesn't sound like a valid excuse to me.

Thanks Bob, that's very similar to what I've done so far... so in the photos ignore the fact that the oil cooler isn't actually there, the bracket holds it. Top of the OC brackets have vibro-stops, then at the bottom/back there's vibro-stops going to the radiator, and also on the bottom of the radiator - and the longerons going from the top to bottom of the radiator are bolted to the bottom engine threaded holes. I still have to adjust this, maybe get it closer to the muffler, as the cowling makes contact with the starboard side of the radiator right now.

Seems to be a popular spot Nev. Other option is on a welded plate on the engine mount, but that requires a separate NACA inlet, duct and shroud.

It's a long time since the 1930's Bob - my demure bride has no problem telling me where she's going. And sending me to the woodshed at the same time.

Nice looking amphib.

I don't think SWMBO will wait that long. She's already choosing vanities so I'll have to wall it in, so I can put water supply and drain pipes through the studs. Good news is though, I only have to plaster and paint the inside (for now.)

Still trying to shoehorn the radiator and oil cooler into the cowl and getting there. But on the long weekend just gone I had to take a break from plane work and install a toilet in the shed. Winter nights are getting a bit cold to go outside, especially for the missus. I did it backwards and put in the loo before the surrounding walls; which does make it a very spacious toilet, but on the good side, gives you a good view while standing...

And Gumtree is free... and whenever someone spots a plane on Gumtree they tell everyone on this site, win win really!

I thought he was talking about air duct (SCAT tubing).

I don't think the footage is faked but it looks more like a noseleg collapse to me.

Wouldn't it be better to register as 19 or VH-E than never fly at all?

That's what happens when you break thru the 80kt barrier.

I remember my grade 9 history teacher telling me that he saw Sabres being sold for $60k in flying condition. This would have been 1986 or thereabouts.

The oil cooler threads are aluminum themselves, I'm pretty sure.

Yep, although they are 13mm thick. I've only got 16mm total on the threads and I need 6 for the top nuts and another 1 for the bracket, leaving 9mm. So I reckon Blueadventures is right and I should just get some scrap 6mm ally and tap it out.

I've found a possible source - https://www.mxstore.com.au/p/Bolt-M22-Locking-Axle-Nut-and-Washer/BMAXN22?gclid=Cj0KCQjwmtGjBhDhARIsAEqfDEfkXphi3afbMAkbixo6yRbsqsag2c60xS7D1yKceZ00IROsfw6G7hwaApr1EALw_wcB - just messaged them to ensure the pitch is 1.5, if so I'm laughing as it's free postage over $20.

Hey OT, thanks so much for trying - that sounds like a lot of effort, I appreciate it! I may have to take Spacey's advice and cut some full size ones down. Thanks again!

Yes, a number of the sites I was looking at trying to source these nuts are woeful. A search function that lets you set the variables of the item you're after is always best.
