    What's the approximate cost of that system from Geiger? Given 31kg I'm guessing 2 battery packs?

    If Mars CASA doesn't do a ramp check, they're all good.

    Soooo... Australia is buying fuel and then putting it back in the ground? Is that the ultimate "direct action" by the coalition? Paying US oil companies to extract oil then put it back? (tongue is firmly in cheek, I know irony doesn't always come through online...)

    Hard to imagine a heat-seeker getting through that lot!

    Congratulations!!

    Sounds idyllic, but what about the "runway picture" for judging your descent?

    I would love to build an electric Spitfire. You could always hang a couple of huge speaker cones in the engine bay and run a soundtrack of a Merlin.

    Funny how that happens, when you stack the committee with people who work in/own/have substantial interests in gas.

    PM sent. Although I'm quite happy to send them to you, if I was doing it over again, I'd get the 750 plans instead. The 701 has MTOW of 500kg where the 750 has 600.

    Been a while!! I finally bit the bullet and did a test piece from gel coat + 2x layers of carbon fibre + peel ply, using polyester resin. I bought an oven tin so I didn't destroy any of my wife's existing ones, did the gel coat first with a paintbrush (might use roller for bigger pieces) then let it cure for a week or 2 before doing the rest. I used 6 x coats of wax, buffed back each time, then a spray release just before the gel coat. It worked a treat - popped out of the mould perfectly. While I'm very happy with the mould release and the gel coat, I put in way too much resin and the part is heavier than it should be. In one photo of the interior you can see one perfect bit where the carbon fibre is showing a shiny coat of resin, the rest is all too thick. I will be far more sparing in application on the real thing.

    Look, there's a documentary about what happens when you give military hardware too much autonomy - it's called "The Terminator". (Ok, so it's not a documentary, but bloody good series of movies! One of the rare ones where the sequel is much better than the first.) The decision to deliberately take a human life - and the responsibility for doing so - must always rest with a human.

    It was getting hot in there. He's just sticking his head out for some cooling.

    Defense acquisition is never about value for money. If Russia or China produced a 5th generation fighter that outflew and outgunned anything that a five eyes country produced, at 1/10th of the price, we still wouldn't get it.

    That was Head In The Clouds, I think.

    Hey folks, Currently in our caravan at Crayfish Creek, leaving tomorrow or Wednesday. Any builders / flyers in the local area who have an aircraft I can drool over? Cheers, Marty

    Wow, that went sideways fast. It was just about the planes for me, and let's face it, if it's happening anywhere else in Aus but your place, you don't get to see them live anyway.

    On now (ABC TV) - hopefully they'll repeat it. Just saw some warbirds - Mustang, Spits, Wirraway, Catalina, DC3, etc etc - plus 3x F35, standard Hornets, Super Hornets, Growler, KC-35's, C-17's, now showing Roulettes. Fantastic day in Canberra by the looks of it - wish I was on the banks of Burley Griffin watching!

    Where d'you find one of those Lisa Juicy figures? 😄

    Cheers Gareth, it was good talking with you! Funny bumping into you again at the restaurant today, but Hobart's a small place. Glad you got home ok and hope QLD clears up this latest cluster pretty quick.

    What am I thinking of? Must be "scrum". I dunno - don't follow sports. I remember there was one bloke called Hopoate who liked whatever it was.

    He might just be a rugby fan.

    Actually I think the entire post was correct. Plus I thought it was easier keeping things here on Earth rather than sticking them in Uranus...

    Mass remains the same, weight is an effect on mass by gravity. Simple to change, if you apply a force of 10G to something with a mass of 0.3kg it will weigh 3kg. If you want it demonstrated, put a 0.3kg weight in a centrifuge on a scale (at the outside) which reads out somewhere visible. As the centrifuge spins up your scale will show the increasing weight until it's 3kg. Postal money order or bank transfer will be fine.

    Zenith leave it up to the builder, so it'd vary from aircraft to aircraft. Mark alodynes a lot of his ally which would protect it even without the black goop. A lot of 701 builders use no primer at all. I went for the middle ground of just using a Dulux etch primer on all surfaces that are joined. Worth noting that 701's are made of 6061-T6 which itself has corrosion resistant properties. But it depends on where it's been left outside - dry hot climate, probably not a problem, but anywhere with rain could pose a lot of problems over 10 years.

    Is that the one that someone had stolen the engine from?
