  1. I'm not highly competitive by nature and so the view I have of aviation is as a gentle and absorbing experience. My shortsightedness in failing to recognise the other, more competitive faction of faster, higher and more extreme forms of activity. I had access to a simple Mk 1 which I enjoyed for its good manners and charm.
  2. Also, I had radio on and was listening to static from ignition. From memory ignition static ceased for the duration of engine miss. Could be something more sinister going on! i have never experienced "icing" in a 2-stroke either. Maybe a fault in the earth connection to Ducati box.
  3. What reason could there be to spoil a beautiful Kitfox with 145hp? They fly perfectly well on 65 (rather small) Rotax ponies via 582.
  4. Anyone had 582 carby icing? Today, at 3,000 and cruise revs I had a brief engine cut (about 1/2 sec). 500 below cloud at 18deg/c. Can't think of anything else it was likely to be. When I landed there appeared to be condensation on the carb bodies.
  5. Lake George on Thursday from the Thruster. Met Peter, a hang glider and paramotor driver at Gearies Gap.
  6. At our strip a Piper Tomahawk, doing circuits elected to fly towards the hill when a stiff easterly was on his nose. Instead of turning x-wind after take off he flew into the downdraft and failed to clear the hill. Expensive lesson but, luckily, in this case not fatal.
  7. The point being made was, I think, how many crashes have there been in the same period of a/c powered by Jab engines? A fair comment because Jabiru has been highlighted by CASA .
  8. Don't know where else to put this, cheers, Don. https://en.wikipedia.org/wiki/Mikoyan-Gurevich_MiG-8
  9. Yep, going asymmetric when you don't know the consequences will surely lead to unpleasant consequence, agreed. Don
  10. And this...for RC
  11. Please note, I am not the "first without sin", Just remember this accident and the fact that, as Yenn says,"Over the years I have seen many instructors and many of them are forgotten as they were poor." The Board of Inquiry concluded that the instructor devised a demonstration of asymmetric flight that was 'inherently dangerous and that was certain to lead to a sudden departure from controlled flight' and that he did not appreciate this. https://aviation-safety.net/database/record.php?id=19911029-0 I'm not wishing to be controversial, a stirrer or indifferent to the suffering of families or others. Just saying. Don
  12. "You idiot! You've killed us all." From memory, the final words of the PIC of the RAAF 707 after the check captain pulled power on both engines on one side off Sale in the Bass Strait. "I've hit the...(Guy cable supporting 2XL's broadcasting mast)." Final transmission from the Snowy's Pilatus Porter, killing the pilot and 2 office girls,as it crashed in ground fog. Cooma Airport, 15miles away was clear. So many preventable tragedies.
  13. Years ago my plane, a VP-2, came with a de-Havilland 60"x30" prop. Its performance was so poor (produced max. 2850 rpm) it was dangerous. I went to Mangalore airshow and measured every prop attached to a VW there. They were about 56" max dia with far less chord and a flatter airfoil with max thickness about 1/4 of the chord. My prop had a Clark-Y type section with max thickness about 1/5 and a blunt leading edge. I attacked, taking 4" off the diameter, removing the brass L/E and savagely reducing the bulk. I placed an epoxy L/E and then had it sprayed white and with red tips and balanced it. When I ran it, tied to a tree with a spring balance, I found the static thrust had reduced from about 150lb to around 120! Well, time to run it along the strip to explore the result. I was shocked to find that the revs had increased to 3600 and it accelerated like a racehorse. I then committed to the air and found that the miserable climb performance had improved to 500fpm. It cruised at 3200 /60kts. I believe that the old prop was acting similar to a fan. It moved more air at zero airspeed giving a thrust figure of about 160. However, the purpose of a propeller is to accelerate the air to a high velocity. It therefore produces more reaction force to the airplane and an increase in performance. The engine was obviously producing more hp and the prop converted this to a more energetic airflow. I'm not trained in physics so am unable to explain in more technically precise language. Simply my experience. (Don't be afraid to experiment, most satisfaction comes from positive experience {or, as Facthunter explains,"Never stop learning."}) Don
  14. Far too adventurous for the management I'm thinking.
  15. A much better plane than the unfortunate Hughes Pocket Rocket I think.
  16. Did my (delayed) BFR last week in a Jabiru. 2 landings and the CFI said that for someone who doesn't fly a Jab they were pretty good .
  17. Wouldn't suit a Cessna driver!! I'd give it a crack 'though.
  18. My mistake...can't tell a bear from a gull:oh yeah: The Rutan SkiGull is an amphibious aircraft designed by Burt Rutan
  19. At around 1230 today we saw a very quiet twin with apparently a T-tail heading S-W over Canberra. This turned out to be a Chaika LLC L65 Seabear. I think that this was designed by Burt Rutan as his ultimate global retirement project. Any comments? Don
  20. Frank, it's horses for courses. If I lived in shorts & t-shirt country it has to be a Drifter. Down here with the white stuff, protection from the elements is king. The T500 has a bag on the rear end that adds weight and hides the fuel and controls. My plane is in good nick with a new wing and 100hr engine. Its about 10 years younger than a Gemini. Don
  21. Don't want a T500 anymore... my T300 is the best!!!
  22. Yeah, and the POS is re-advertised with a POS Verner boat anchor. Caveat emptor!!!
  23. Here's me helping Frank with mowing at Lake Tinaroo on the Tablelands a few weeks ago. Fun when you get the hang of steering.[ATTACH=full]55782[/ATTAC[/ATTACH]
  24. Took this from Mt Taylor behind my house on my walk yesterday. Bet you're jealous eh Frank?
  25. So... does anyone have information about Tony Hayes sourced components? Particularly his pods? Don
