    Okey Flighty, I’ll bite. Who are these Lunatic Greenies? The people who have now been proven right. Have you noticed how the anti-green side constantly shifts their position as they retreat in the face of reality? Perhaps you want to carry on living like we have for decades, as if you have no responsibility for the effects on others? Change is here, it’s good for us, so get on board.

    That resonates with me, CS. On arrival at Termora one year he and Don Windsor came running over as my plane stopped. I’ve never felt so welcomed. I remember the boy every tiem I scan my panel; he sold me my fuel flow and pressure gauges, which are still doing their job many years later.

    The 1937 crash was discussed here:

    Crikey PM, half a century? Even the motor car was phased in to replace horses in a couple of decades and that was a century ago! Social and technological changes are accelerating at an astonishing speed, as this graph shows: Our whole civilzation could collapse in less than 50 years and there are many triggers lining up to do us in. Pollution from fossil fuels is just one of these threats, but at least there is a global movement to do something about it. The world rapidly phased out CFCs to stop the destruction of the Ozone layer, why can’t we do the same with fossil fuels?

    This photographer has captured a unique view of bird flight:

    YR is also impressive.

    I agree in principal, but it depends on where are. Our district is currently like a rice padi, so you’d be likely to dig in and end-over in any of padocks, even the better-drained hill slopes. After the drought caused so much destocking, many paddocks have grass over your head, so you’d never see logs and rocks. Rural roads may be a better bet due to less traffic and roadside furniture.

    Looks like an early model Spit, without bubble in the canopy. Good hand-colouring job or actual colour pic?

    Air pressure at ground level varies considerably as highs and lows passover. I often have to crank my altimeter back a couple of hundred feet to match local elevation. Last Wednesday it was out more than ever. Five minutes into my flight I noticed the altimeter was reading 1,000’ lower than OzRunways….Woops- I’d cranked in the wrong direction.

    Uphill slope, slotted easily into the traffic flow, but hogged the centre lane a bit.

    Good work, CS. Warwick is special to me- I was born there. Years ago when I needed to fly in for a family gathering, I phoned around and a local pilot lent me his hangar for the weekend; a great kindness for a stranger.

    I once came across a mini on fire. Stopped, got out my extinguisher and rushed across to help. The owner shooed me away, saying “let it burn”. Insurance?
  14. Old Koreelah
    That’s exactly how my first solo happened: no warning, he just got out, said go for it and closed the canopy. I hadn’t yet done stalls and incipients, etc. but survived the ride. That instructor’s approach led to disaster for a later student and the aircraft.

    That article gives me more confidance that my current low rate of water injection will help keep the engine cool, clean and reliable. The claim that water reduces the chances of detonation is great news for flimsy engines running uncertified fuels.
  16. Old Koreelah
    Wise words, OT. I gave a PLB to my brother, who spends too much time working alone with horses, dodgy cattle and machinery. He gave it back after a week, but years later he surprised me by carrying a phone, but it not much plurry use in the rugged country he works in. I religiously carry my phone and PLB on me, so they escape with me.

    Bruce at the moment I’m giving it about 20% water and 80% Shell 98. The fire hasn’t shown any signs of going out and its running a little cooler than expected, but I’ve yet to do proper comparison tests in flight. Plenty of other projects to keep me busy, so I might keep using the current tiny little pump for a few more flights. When the proper hot weather hits I might install a bigger pump.
  18. Old Koreelah
    Yep. That’s what got me off the fence. My Jab runs a little rich and has quite a lot of carbon inside. Two doses of Mr. Subaru’s cleaner in a spraycan seem to have helped a little, but I’ve also had the engine run on after shutting off the spark, so the least carbon buildup the better.
  19. Old Koreelah
    Yes Nev, I’ve been ground-testing each stage by tethering the tailwheel to a post. Why add methanol?
  20. Old Koreelah
    Quite true, Nev. That’s the most my current little pump will deliver. The next step is to fit a windscreen washer pump, but I’d need a valve to control the extra flow- I don’t want to put out the fire! What does the methanol do? I presume it helps avoid icing and adds power; I don’t need any more power and I’m wary of any alcohol getting near all those rubber seals.

    Yesterday the rice padis were drying out and I got to test-fly my water injector. Full throttle climb past 5,000’ saw CHTs creep up to 156C, where during previous tests they spiked well over 160 in a fraction of that time. That convinces me that even at only 80ml/minute, the water is helping with cooling. One interesting change was EGTs; they normally stay fairly even around 650C but while the water was being injected, No. 4 was up around 720.

    The video related to a foreign country; how much of it is relevant to Australia?

    Not exactly aviation, but another gutsy woman; this one changed the world, but is unknown.

    Ideally, a pre-warmer and pump to get that oil circulating before we crank the engine. It could be plugged into any external oil line. During WWII winters, the Swedish Air Force kept oil hot and added it their fighter engines just before they were scrambled.

    Lavochkin La-7

    A beautiful-looking aircraft. The Soviets produced vast numbers of an impressive range of war weapons that we in the West heard little about.
