    Okay if my problem is from the prop would it be noticeable below 5000 but smooth out above or would it be through the whole rev range
  2. rhtrudder
    Has anyone fitted one to the flywheel end, looks easy enough, do you think it would make a difference, my plane has a noticeable vibration under 5000 feel it through the cabin support, I realize the engines run like a thrashing machine up at cruise, you only have to take you headsets off, so it may be just what it is,

    Hi are you still bringing in the balancers
  4. rhtrudder
    Not the original builder

    Just found out the pilot was a local boy from Tongala,I took him up a couple of years ago for his first flight, he was very keen and soon had his instructors ticket and was possibly on his way to a commercial, looks like his brother and cousin were lost as well, I think he had relatives in the area I guess that’s why all the orbits, he had only just taken over the plane , sad times.

    I thought the bristell was aluminum, but it looks like fiberglass the way the fire took hold

    What’s the safest detergent to use on a aluminum plane, I figure ph neutral, but should keep away from phosphate , most of the auto cleaners have sodium in some form, a lot to choose from

    In the past if I have left one off I could barely notice the difference but not now , both sides the same, feels like it will cut out, I’ve never come across this information before, can drop up to 500, at 4000 , just found out the 914 runs one side a bit more advanced , I guess to help with detonation, read somewhere the earths off the cdi and coils can corrode, just cleaned them up , fly tomorrow and hope my imagination was the trouble all along

    Still trying to figure out my engine, switch between the mags below 4000 not much drop, up in cruise, above 5000, the is a big drop on both sides, I know the ignition systems are separate from each other but is there something common to effect both

    Planning a trip from northern Victoria heading up north along the darling , still in the planning stages, anyone welcome to tag along, Greg

    Don’t think my 914 has bounced back, maybe something to do with the reduction gearing
  12. rhtrudder
    I guess that’s why the the hot up mobs offer to weld up the crankshaft to take the strain of the extra power, I think I will leave it standard
  13. rhtrudder
    True, the 914 is a 80hp with a turbo, low compression on start up , HP comes up when over 30 on the map gauge

    How many hrs on your engine
  15. rhtrudder
    Worst cylinder was no 2, left front, could definitely hear bubbling in the oil tank, so I reckon the valves are good, 70/80 , the bore scope sounds a good idea but I’m not sure I’d know what I would be looking at, wonder if just a set of rings would make a difference, read that the bores hardly wear, hard as a cats head, found on eBay a full set of pistons and cylinders only 95hrs, $1200 plus freight from the US could be a scam but might be worth the gamble.
  16. rhtrudder
    Would it be possible to replace the pistons and rings and maybe valve guides give the old cylinders a hone and go again, I reckon the bottom end looks solid, could be a cheap way out although I have out jewed myself in the past with mixed results
  17. rhtrudder
    Only private flying, having trouble trying to justify over $50K on a replacement so I guess I keep up the service and hope for the best, worked okay so far , Wally tells me plenty have well over 3000 up
  18. rhtrudder
    Over 1900 hrs on my engine, no 2 always felt a bit soft in compression when flipping over the prop, leak down showed 70/80 , rest about 75/80 , going past the rings , should this be a concern or just keep flying, engine doesn’t use any more oil than usual
  19. rhtrudder
    Thanks
  20. rhtrudder
    Maybe end up going through the week

    Hi anyone flown the VFR track through Nowra , I’ll be heading south, wondering if it’s easy enough, Greg
  22. rhtrudder
    At around 4500 revs my engine definitely has increased vibration ,below 4000 and above 5000 it’s good , I think I come across this in another thread, it’s fitted with a O2 sensor so I know the mixture is correct, prop been balanced, could this be harmonics , has anyone else come across this
  23. rhtrudder
    Noticed a soft compression one one cylinder so ran through a leak down test sat the gauge on 80 , three read 77psi but the sick one was down to 75 psi , I guess not a lot of difference, could hear a faint bubble in the oil tank , engine has 1850 hrs up, would a set of rings an a hone fix this , back in my 2 stroke days rebored to get everything round , engine is a 914
  24. rhtrudder
    Dumb question, but how do you access the track logs from the skyecho
  25. rhtrudder
    If there is a DPDT switch could that be the problem, not easy to get to the trim motor
