    If it's the same stuff they sent me (it should be, I navigated to the ad from my purchased list) then the below should put your mind at ease. That's 20mm OD oil line, goes on easy.

    You didn't hear an alarm and a mechanical voice saying "Missile launch... missile launch..."?

    A couple of pics of it Skippy...

    OT, paid 2/2/23, delivered 8/2/23 - so 6 days. Hong Kong is usually quicker than many locations in mainland China.

    Skippy, I bought 3 lengths of this - seems like good stuff: https://www.ebay.com.au/itm/Red-3-feet-Fire-Sleeve-Braid-Flame-Heat-Shield-3-4-Fits-10AN-for-Oil-Fuel-Lines-/372637527814?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=705-154756-20017-0

    Happy to be corrected here, but I wouldn't have thought that a difference in distance between manifold and carbs would matter in the least. Think of the fuel system like an irrigation setup, the garden hose that's 10m long gives the same pressure as the one that's 12m long. If there's no air in the fuel system, why would it matter?

    That's very nice work @rodgerc. What's the whitish stuff on the threads?
  8. Marty_d
    Sorry Mike! For some reason the engine photo reminded me of iBob's installation and I obviously went by that instead of looking at who posted it... 🤔
  9. Marty_d
    Thanks gents. So Bob - that's all brass fittings you're using? Thanks Skippy re the Mikuni jets. They seem to have an M5 thread - Bob in your photo have you pressed the jet into the end of the normal barb with the thread outward?

    There's a challenge and a business opportunity for you OK. I've seen your trailer which is a masterpiece of engineering - surely you can produce a lower-cost hydraulic moving Jabiru cabin?

    Help required please... I want to create the fuel manifold as shown by the Rotax Installation Manual, (image below). Banjo bolts are easily accessible as are the fittings. They're available in M10 or M12 in various threads which I can tap myself. So all I need to manufacture is the block itself which clamps onto the crossover pipe. Essentially it's just a solid block with a threaded vertical hole right through for two banjo bolts to go into, and an unthreaded hole for the crossover pipe to go through with a small bolt to tighten it onto the pipe. Questions: 1. What would this be best manufactured from? Alloy? Any particular type? 2. What about the banjo bolts? They're available in alloy, zinc coated steel and stainless... what's best for fuel? 3. The barb for the return line to tank needs to be restricted (is it 0.35mm? The manual says "PILOT JET 35"), and the barb for the fuel pressure gauge needs to be restricted to 0.5mm. How is this usually achieved - can you buy barbs that are sealed at the end and drill them to the correct size, or is there some kind of restrictor available which seems to be suggested by 6 below? As always any suggestions gratefully received. Cheers, Marty

    Man of the people, huh! Nothing like parking your Roller where everyone else has to trudge in.

    Big day today - for the first time a wing was put in position! Very relieved to find that the mounting surfaces meet neatly. I finished the fuel line on that wing then removed it again, would have been difficult to get to the loo with it in position.
  14. Marty_d
    But seriously, how does that happen? Caught cheating by a wife who can drive an excavator?

    Amazingly narrow wings and tiny HS. Looks like the whole fuselage is a lifting body.
  16. Marty_d
    No, but it'd be nice to sit in it once or twice and then sell it, and buy something far cheaper.
  17. Marty_d
    Bugger, I thought my luck might change! Not this time.
  18. Marty_d
    Thanks all! some good leads there.

    I spent a while in Repco the other day looking for suitable 25mm ID hose for the radiator runs. Couldn't find anything and everything was hellishly expensive anyway given I'd need to buy several to get the right bends in it. Just in terms of the Gemini radiator hose Skippy - was searching online for that but it always seems to be 30 - 34mm, not 25 as we need for the Rotax connections? What other options are there - looking at this (Aeroflow silicone heater hose) - handles up to 180 and it looks like it's got some spiral reinforcement. Can't find any data on bend radii though. Would something like that be suitable for the 25mm sections?
  20. Marty_d
    Thanks Mike, will do. They're coming from China so I'm not expecting them for a while.

    What about the hundreds that lost their lives on a refugee boat at the same time this was happening? Did the wealthy countries spend any money on them while spending millions looking for 5 men?
  22. Marty_d
    Great idea Nev. sfGnome, if you were in Tassie instead of NSW I'd be tempted to join a building group too.

    The Rotax regulator is just a Ducati part anyway isn't it?
  24. Marty_d
    Actually - wouldn't rollover protection be afforded by the A frame kingpost structure that holds the upper wires?
  25. Marty_d
    Probably wouldn't be hard to design a quick-release rollover bar. Leave it off for ground viewing, put it on before flight.
