  1. I know a bloke who flew one out of a strip 384 metres from fence to fence for years.
  2. Boroscope check of cylinders of my Jabiru 2200 engine for the UL450 project. This engine has been in storage (inhibited) since 2000. The barrels are steel (4130 I believe) and this is how they look - shiny with the hone marks clearly visible. Brown stuff on the bottom surface and on the piston is the rust inhibitor oil.
  3. Here are a few photos of my under cowls set up. I'll get photos of the sump cooling duct later...
  4. A recent flight from Drouin, two Edge X's, my 582/Streak and Tony's 503 Wizard. I'm learning iMovie and this is my first effort.
  5. CHT probe on no. 4. I'd prefer the temperatures to be regarded as too low and inefficient than risk dropping a valve seat. BTW I have been running a mixture control for almost 200 hours and monitor EGT and plug colour.
  6. Absolutely correct. That was the aim and it appears to work very well.
  7. Bruce’s SK has the same cowls as mine and probably similar performance. He is trying to resolve high CHT’s. What I have done works.
  8. This has worked for me. Move the oil cooler to the rear of the engine and duct air to it via a side naca duct (like carby inlet), reduce the size of the lower air intake that was previously there for the engine mounted oil cooler, built a close fitting duct from this reduced inlet to the sump. Max CHT less than 140 on the ground which quickly reduces to 110 for climb at 80 knots (700-1000 fpm), cruise CHT at 100 knots 105 degrees C. I had a similar setup on my Corby Starlet and replicated it on the Jabiru. No need for cowl skirt or big mods to inlets. I did add a bit to the cooling ducts to prevent air from going under the front cylinders.
  9. It won’t be too hard to work out from the wreckage.
  10. From SAFA: There have been a number of WSM members who have expressed concern over reported safety of the wing involved in the Alex Blanch accident, near Newcastle NSW. At this stage we have carried out preliminary inspections of the wing and there is no indication that it "folded up" as has been reported in the media. The Streak 3 wing type has operated without incident for over 2 decades. This particular wing has been utilised on this aircraft for the past 3 years. We have initiated an independent detailed analysis of the wing, in an effort to determine if it contributed to causation. Reiterating the point that at this stage we have no reason to suspect that there is a systemic issue with the wing type.
  11. He probably took his eyes off the instruments for more than 3 seconds......
  12. They must cut and paste just as the numpty wrote it!
  13. No 3. If the investigation reveals a negative G break to the leading edge/s that would indicate a tumble. Also, damage to the base bar from impact with the front strut of the trike would support this scenario.
  14. Next time I'm at the hangar with the cowls off will take photos outlining what I've done. The balance scat hose between the cooling ducts sounds like a good idea too. The main thing I did was reduce the pressurising of the lower cowl be moving the oil cooler to the rear of the engine, ducting air to it from another vaca duct on the right hand side of cowl. I can control this air to the oil cooler from the cockpit - monitoring oil temperature.
