  1. I keep wondering why people will go from 100LL Avgas to 95 Mogas? Just because engine manufacturers say you can use a minimum of 95 Ron fuels, doesn't mean this is the best fuel to use. 98 Mogas is still a lot cheaper than 100LL (if that's the reason to use Mogas). A lot of the Avgas fuels, specifically in aero engines, often caused run-on, this being the reason most aircraft engines use an idle cutoff, rather than just killing the mags. But more to the point, run-on is more likely to be caused by engines being run hotter than they should, in conjunction with carbi's set up a bit lean at idle?
  2. From what I can see, it is usually LESS of the tail wheel type, that end up on their back.
  3. I would have thought the easiest way to solve the problem was, learn to fly a tail dragger, build a taildragger (as Vans envisioned them), and only worry about breaking propellors if you get carried away with the brakes. Flame suit on, ready for the 'training wheel' set
  4. This AD was probably brought about by this report; http://www.atsb.gov.au/publications/investigation_reports/2005/aair/aair200501905.aspx Which includes this photo; So the text is referring to swaged terminals, and possibly any of the 'thin' looking terminals typical to control systems. or, And so on......
  5. With regards the Kooka', is actually ALL wood, fuselage included. where my flying all started:chuffed:
  6. One see's a lot of PT-6's doing the vertical descent thing, and usually getting away with it. I, and probably ozzie are aware that some Garrets don't take kindly to sort this treatment, maybe there is a possible problem with the PT-6 under these conditions?
  7. My feeling as well...? An empty Pac 750 would glide pretty well, but if it's caught fire, might be better to get out.
  8. My fathers name was Len if you're asking me... I've done some modelling in the past as well. Yes, I'm an ex-Sandgroper. Some of my modelling stuff in the google link below.
  9. They don't always work...;
  10. Talking rocket powered, check this out !! https://www.youtube.com/watch?v=wL8Pv2J4HbE
  11. Love the little twin Cox, how did it run?
  12. The Solar T-62 core , typically uses between 60 and 80 litres an hour.
  13. Many have suggested this, and I half agree, but your point fell over when you mentioned two 90kg pilots. This means I'm limited to 80kg passenger/students. I was happy enough with 544kg when we had it. We also needed to tie in with a stall speed, thereby giving us the low inertia thing we are were supposed to hold to... Bring on RPL, then all the old GA pilots can go back to their Cessnas, and leave us to fly recreationally.
  14. So, what was it?
  15. Remember that the original prototype Jabiru flew with a Rotax two stroke......
  16. Regarding rough running with 912's, you'll probably find it occurs as you throttle down through the 'zero thrust' rpm. At this point there is no load through the gearbox and the crankshaft impulses will excite the backlash in the box. Below that, the aircraft is pushing the prop.
  17. Hey, I resemble that remark, well, sort of... This is from a Simpson's 'create a likeness' page that I can't find anymore. Megh...
  18. This idea has been touted about for many years, especially after the debacle of storing the C130A's at Point Cook, and having them corrode away in the sea air. However, I have heard from a reliable source, that storage at many central Australian locations turns out to be just as bad due to the number of (sometimes) dry salt lakes around.
  19. Yeah, looked like you were about to suffer a birdstrike from BEHIND
  20. Things are definitely looking on the up..... Had a registration that was a bit of a doozy; change of ownership (from deceased estate), back into the 'fold' (unregistered for a few years) and change of designation (95:10 to 19-xxxx). Filled out reams of paperwork, stat. dec. for ownership, numerous photos and weight & balance sheet. Scanned the whole lot, forwarded by email (about 7.3MB); TWENTY DAYS !!!! Now if the weather could just clear I can do a bit of re-test flying....
  21. All the Lightwings use heel brakes, following on from Piper Cubs and Austers before them. Doesn't take too much practice to get a 'feel' for heel brakes. If you look at a Lightwing set-up, you can see that it is possible to vary the leverage/load on the cables depending on the distance from the pivot.
  22. If you're using a split/twin rudder airbrake system, you might as well hook the wheel brakes straight to the rudder pedals, no toe brakes hinging required. Ground wheel braking/steering will occur the same as air rudder braking/steering. Then just use a castoring nosewheel/tailwheel. The only downside is the return spring pressure required to keep the rudders straight in flight. To that end, if you pivot the rudder pedals 'above' the floor (say about 2") then the weight of your feet/legs will hold the pedals 'closed' (back) requiring you to push with your toes for activation. And put the return springs at the rudders, not the pedals.
  23. I think I've heard that if you send your expired 300 hour engine to them for a 'zero' time rebuild, it costs around $3500, then you add postage.... If you are starting from scratch, meaning you also need a radiator, oil tank, gear box, air filter and starter, the price comes to about $8000? Depending if you are building something new (kit or plan), then the list goes on into hoses, engine mount, starter relay, regulator/rectifier, EGT, CHT/water temp probes and gauges. And don't forget the prop!
  24. 'Burping' is also dependant on the position of the oil tank relative to the height of the engine. Gazelle and Skyfox tanks tend to be higher and drain oil back into the engine. Foxbat tanks tend to be lower, so most of the oil stays in the tank. A cold engine will 'bleed' compression faster than a hot engine, so 'cold' turning will burp the tank quicker.
  25. Got a new replacement 582 last year from Flood's for $5500. Came with new carbs, new exhaust (cylinder to tailpipe and springs!), new plugs and even a bottle of the new AeroShell two stroke aviation oil (sounds like a contradiction in terms I know?), should point out the oil had an expired shelf life, but.....? Engine pre-fitted with oil injection and pull start, just add your own starter and gearbox, and your off with a NEW motor. AND, I still have the old motor (which was running well) for an uncertified project, or sale to others for same (I'm keeping it at the moment).
