    My father was involved with manufacturing parts in china as a lower cost option for the market. they sent a sample to be replicated exactly as supplied.... which they did right up to the "made in XXX country" stamp. But yes, he had to make regular trips over to inspect the production. and ensure that there was no deviation. as others mentioned the biggest problem is design creep where they change or substitute things. he mentioned that the Chinese quality control was to lessen the quality until it became unusable. then walk it back one step.

    maybe its the pilot that has done his bucket list trip, and decided the plane isn't practical to keep not much point having a touring plane if your not using it. been done for a few years with adventure motorcycles, buy it - do the big trip and sell without loss of value.

    I'm sure a quick search on YouTube will provide a tutorial vid. plenty of people uploading that stuff

    That's the one. there is a reason the SU-24 is still flying in many air forces. and aircraft such as the tornado were kept for the strike role long after their replacement for air to air roles.

    Makes sense, we need something with long legs to be a factor in any indo-pacific conflict. we lost the capability to strike un-refueled when we retired the F-111 and there aren't many options for a new bomber or long range strike aircraft. shame we never got the platypus

    if only it was painted green......

    Interesting that another student was briefed at the same time, and likely the only reason we know of the incorrect spin recovery being taught for this aircraft. I've heard of schools briefing students together. but I've only experienced individual briefs' immediately before the flight. (or do the larger theory lessons when the flight is cancelled due to weather)

    My understanding is that 95 is regulated. But the manufacturers can put whatever they like in 98. Which is why all the manufacturers advertise their 98 as a special blend. Notice that these days it's advertised for its detergents "cleaner engine' not any performance benefits

    interestingly with motorcycle's it was always completely drain the tank and leave it empty and dry so that the fuel didn't turn to varnish/jelly and destroy the fuel pump and lines. or leave it completely full with some stabilizer, so the moisture couldn't get in and rust the fuel tank. when it was left half is when everything would be completely destroyed. would only take a few months of sitting to leave it completely cactus. and 98 fuel was the absolute worst for it.

    Looks like my memory was pretty good, 2900rpm cruise is about 15L an hour from the Jabiru POH

    I did my training in a J160 and I thought we used 15L an hour as the rule of thumb for fuel usage

    it happens all the time to our motorcycles. parents lifting kids on, or the young foreign student wanting a photo for his friends. no asking, no caring just sit on. used to work for a Harley dealership... remember having a nice conversation with a patched member (nicest customers for me to deal with. mutual interest for the bikes and often on a first name basis. polite and well mannered with me at the counter) anyway this day an exchange student was out and sat on his Harley to take a selfie... wonder if it captured the punch that took him to ground. that was the first of a few punches I saw fly for that. (wasn't often done out the front of our store - respect for the place of business) people just don't care any more, people with young kids are the worst "he's just curious, he's just playing" no cares. used to work at motorcycle dealerships and we hated the grandparents taking the kids out for the day, and the young dad taking the kids out. so many close calls. suddenly see they wake up to fact they need to keep them close, when we tell them that its a 100k bike that their little gremlin is about to try and climb on.

    classic example of the difference between campaign, and the actual governance. they were smart - shut up during the campaign and sold themselves as the moderate party focused on climate change. think they had a real shot at offering a third party - but there members are too used to acting like an independent when given the soap box. be interesting to see if they can get the extremism out before the next election.

    Nah, the greens have stuffed themselves at the moment. with the whole not standing in front of the flag, and declaring the parliament invalid. don't think the government wants to be seen as working with them

    There is a great section in eric winkle brown's auto biography about his test flight in it. having prisoners of war as the ground crew, that had to have signed statements that they wouldn't be punished if things went wrong before they would touch it. sounds like an awesome experience but a short range, and limited tactic - basically rocket up - dive down at a bomber, ignite again to climb. then dive once more and land
  16. spenaroo
    yeah, I think any serious change will come from re-imagined production methods. we started with rag and tube, and went to composites. frames to monocoque. the next method will need to incorporate batteries into the structure, instead of thinking of it as a fuel cell to bolt in. interesting to think of weight and balance, your take off and landing will be the same.

    https://www.motorcycle.com/features/world-exclusive-ducati-v21l-motoe-prototype-first-look.html is the article I quoted from, worth a read to see just what the obsession with weight entails. and better specs, and how its all designed together to achieve it. I misread, your right it is 110kg is for the battery (I only skimmed the article before work) the total bike weight is 220kg, a Panigale V2 is 200kg kerb weight (closest performance specs). probably take 20kg out for a race bike for around 180kg (no lights, weight fairings and exhaust)

    I'm wondering if the technology is being pulled from the wrong places. there is a large growing market for electric motorcycles. Ducati release their new electric race bike today. all the emphasis on a motorcycle is weight - not really a concern with cars and trucks "According to Ducati, the MotoE racer has an output of 110kW (roughly 150 horsepower) and 140Nm of torque. As for the battery pack, it’s comprised of 1,152 cylindrical 21700 type cells – the same cells you’ll find in a Tesla. It weighs 242.4 lbs. (110 kg) and has a capacity of 18 kWh. What’s interesting about the pack is its orientation – tilted back within the chassis – and the fact it’s not a purely rectangular shape but rather a complex shape meant to fill the void within the middle of the bike. Naturally, it’s housed in carbon fiber, and like the Panigale V4 production bike, it’s attached to a front subframe, making it a stressed member of the chassis." probably take 30-40kg off for wheels, tires, frames. makes it look alot better to strap in an aircraft. plus its built with air cooling in mind. the idea of using the battery as a stressed member also helps lighten the complete package. my take away from this is that the best possible way to make it viable is a ground up build. not a conversion of existing aircraft.

    funnily enough I just had a chat about this over the weekend with a mate, who used to work for a defense contractor was out golfing with him and checked flightradar24 to see what the helicopter we could hear was. showed him and he was laughing as he told me they had it running on a big screen main screen in the operations rooms. he reckons it takes care of everything with a transponder, so they use it to eliminate them as knowns on other sensors.

    Looks like I misunderstood, read those same comments from a different article. Seems like it was just his personal favourite. I originally interpreted it as having been something more special then a regular lightning. (Which I why I put those bits that lead me down that path in bold) "The Lightning was an exceptional aircraft in every respect, but XR749 was one of the best of the best. It is probably the best aircraft that I will ever have had the privilege to fly. Because of her tail code BM, she was known as 'Big Mother', although the tail code changed to BO for her last few months on 11 before joining the LTF in January 1985. She was a very hot ship, even for a Lightning. She remained my aircraft for all her time on 11 Sqn despite my being entitled to an F6 as I moved up the squadron pecking order. I invariably asked for her to be allocated to me for the major exercises such as MALLET BLOW, OSEX, and ELDER FOREST despite her being a short range F3 - there were invariably plenty of tankers about!" "Mike and his team spent the night before in the hangar polishing XR749 which he borrowed from the LTF for the occasion"

    Yeah but the idea was you could be 75kt on final. 65kts over the fence. And still touchdown without floating the whole runway. I'd have to check my notes though. Havent flown it in a while
  22. spenaroo
    True, but like the op posted I find most people avoid refer to the A32 as a Foxbat anyway. Yeah, they also put in thicker windscreens. And I thought the tyres might have been bigger too. Matches what I was told about making them more draggy to better match speeds on final closer to the warriors, so circuit seperation was maintained
  23. spenaroo
    the information I was reading, is that they couldn't pass the Concorde from the rear. and the lightning was hotted up just for the exercise.
  24. spenaroo
    I know several of the SOAR bats ended up at Lillydale with some modifications to make them more suitable for the grass fields.

    What about the mig 25 or 31, it has the speed, and the altitude to out run and out climb the Concorde the Lightning was just the only fighter with the opportunity to intercept one... Though a Tornado was the one to take this picture - apparently they throttled the Concorde back to get the shot though (quick google shows the F15 specs as being possible to intercept at altitude too)
