    Yes Nev, that seems the obvious reason. Those long legs would have benefited from cross-bracing on bumpy ground.

    Red is that a special axle joining the main wheels?

    This discussion might save a life. Despite all my training. I’ve become less wary of wind sheer, to the extent that i recently took great pride in getting my little plane stopped before the end of the tar at the start of our strip- that’s 180m. Keeping an eye on the sock might give warning of wind sheer, but a sudden downdraught would have put me into the fence. In future my aiming point will be the first or second gable- 180m further along.

    But I hope there was enough “give” to absorb some of the impact. Yonks ago a Blanic spun all the way to the ground and the pilot walked away- one wing hit first, cushioning the arrival.
  5. Old Koreelah
    I dimly recall a few lessons holding a stalling Blanik’s wings level with rudder, but every time I’ve tried that in my short-winged Jodel my feet are too slow.

    Kevin it seems your prop is pitched at the safest angle. Not loaded too much. Testing mine while tethered to a post gives a max of 2700. That may not be due to prop pitch alone (standard wooden Jab 60x42) but perhaps power being limited by my hydraulic tappet not opening as wide as solid lifters. Takeoff WOT is 3000, showing 21 l/h on the Mizer. The only time I’ve been game to use WOT in level flight (coming home late in the day in silky smooth air) I saw about 3200. That took you right over my home district, which I’m yet to fly over. Lots of yowie country, few open paddocks, almost no landing strips. I hope to fly in to visit family one day, after I’ve improved my skills and my plane.

    The hooked cross was seen all over the world for several years before the war broke out. Fascinating that even in 1934, American aircraft were obviously a generation ahead. Hitler should have travelled a bit to learn about the real world.

    A Cherokee is parked at our airport and it has a pronounced nose-high stance. Like a few classic low-wings with short main wheel legs, I guess that is to avoid prop strike, but it also seems to have a significant AoA just sitting there. What impact on your flying would that have?
  9. Old Koreelah
    I presume your 701 will be using lots of unpaved landing areas. Plenty of grass strips would give your tips a tickle up.

    Just re-checked my post: A well-respected LAME I know always advised overproping (and having a little carb heat all the time). Lots of Jab owners are happy with the results. What I meant to say was he advised against too high a pitch- in other words, let the engine rev rather than lug. (I presume a lugging engine is more likely to suffer detonation).

    One of our club members had no end of problems with his CS prop. He made sure to select the fixed-pitch prop option on his next plane. A well-respected LAME I know always advised overproping (and having a little carb heat all the time). Lots of Jab owners are happy with the results. The couple of cruise knots you lose are insignificant compared to a buggered engine.

    My mum’s war diaries mention that the citizens of Taree proudly donated the money to buy a Spitfire; either 20,000 or 50,000 quid from memory.

    …and earlier. During the Peking to Paris car race one entrant had a total ignition failure in the middle of Siberia. A professor at a nearby institution was called in. He knew nothing of cars or their engines, but figured out how the magneto worked and made them a new one.

    There was a Staggerwing under restoration at Mandeville, NZ in c.2012. Red of course.

    Several people have used a tube to join the two side, but this design goes further: I’d like to hear how this one performs in real-world flying. As stated previously, the outlets under big Cessna engines are tiny, but seem to work fine. Maybe their higher speed is one factor, but the augmentor effect of having the exhaust pipes in the centre of the outlet cannot be discounted.
  16. Old Koreelah
    I suspected as much: my fuel burn is noticeably lower since switching to 98. Our little town is fortunate to have a fuel outlet owned for generations by a local family and managed by a bloke we all know and trust. His brother is a pilot, which is one reason he stocks aviation oils. He has assured me of the quality of their 98.

    Altho modern reversing radar seems reliable, why not consider a thin, flexible probe? Soviet/Russian space capsules use such a device to trigger the retro blast that slows the last couple of metres of descent. Like most of their stuff, it’s simple, cheap and dependable.

    Rob one of our club’s regulars arrived in a Foxcon 100 recently. He’s based near you, and has a wealth of aviation experience. I’ll send you a personal message.

    Years ago a drunk took a shortcut across the railway line just south of Tamworth and got his 4WD “bogged” on the line. I believe he had to pay for the damage to the XPT.
  20. Old Koreelah
    That stall speed puts it in the realm of the AN-2!
  21. Old Koreelah
    Nice plane, Red; you seem to have made an error with stall speed.
  22. Old Koreelah
    ...and miss out in all the fun?
  23. Old Koreelah
    Thanks Turbs. A dligent pilot must read to page 29 before seeing any actual numbers… and I guess that is the “plain English” version. I suspect they don’t actually want us to read the rules.
  24. Old Koreelah
    Even if he wanted to stop, it’s a big, long, heavy item. Spare a thought for train drivers, many of whom have had a front-row seat to tragedy. My neighbour has had a couple of people calmly step in front of him.

    I have it on good authority that to start a Jab 2.2, warm up, taxi to far end of runway, take off and climb to about 500’ burns slightly more than one litre of fuel.
