  1. A very long time since I've seen a 912 with those boxed ignitions, looks like a proper job on the mount
  2. Could you explain this comment?, from my understanding a blocked vent would restrict movement of the diaphragm which would reduce flow/pressure to some extent how would this cause a pressure rise? sorry If I'm misreading your comment
  3. Having moved my Oil cooler to a position that allows its own air intake instead of piggybacked behind the Coolant radiator, I now have the opposite problem of over cooling the oil. cant get max above 80c so will have to blank some of the oil cooler probably use neoprene wrap...not a problem But allong with the low max temps its also taking ages to reach temp before flying so I'm gonna fit a thermostat. (thermostasis unit) Was just wondering do any of you guys fit them?, or are your ambient temps high enough that warm up is hardly ever a concern?
  4. Theres been a number of flights between interested parties along the persian gulf recently, no doubt high ranking officials involved in various talks. They will be coordinated with Israel and Iran and protected by the forces in the gulf. ETD is an etihad flight the UAE airline One flew right up the middle of Iran yesterday which seemed extraordinary
  5. Sorry, what comment?
  6. Looks like an early Hermes 900, I believe current fitment has been upgraded to Rotax 916IS
  7. structurally thats a very efficient design triangle are good. Aerodynamically, probably not so great
  8. The picture is an obvious joke, mainly at the expense of the Cherokee, its not supposed to be an accurate performance chart
  9. Thought I might be being a bit harsh so just watched another of his titled as an in depth analysis of an E 175 Gear incident, he makes assumptions as to what the crew did and then explains an emergency gear down system that this aircraft doesnt even have I'll give him 5/10
  10. I've seen a few of this guys videos posted here now, Can't say I find him much of an analyst he just seems to repeat obvious stuff.
  11. My father en-route to NZ had a stop off in Chicago some years ago (dont remember what airline). The barely trained monkeys there kept him detained for 4 hours as he could not produce the required thumbprint from both hands and therefore the box on the form could not be ticked My father had lost one arm in an accident 30 years before. I have good friends in America and have travelled some there mostly west coast, I'll see what happens in 4 years time before considering further visits
  12. Actually looking at that pic it isnt even a Westland Whirlwind anyway, lol ...ball of confusion ...aah got it now its a WESTLAND WELKIN Apologies for the multi posts...it was the Wessex thing that got me started on my confused ramble
  13. GWH, where did you get that Max speed figure from?, it was nowhere near as fast as that P.S. Are you perhaps confusing it with the vaguely similar looking De havilland Hornet that they reckoned could do 475mph
  14. Aah Whirlwind. I was expecting to see
  15. Looks to be a single piston not 2 opposing?, if so it definately needs to have some float sideways. If this is the case a clean pin with some anti sieze on and no grooves in the pin is the way to go
  16. I tend to use MX type motorcycle grips, ODI make decent ones
  17. Pictures I've seen show members of the public wandering around the wreckage with no attempts by the authorities to kep them away. There will much Carbon fibre floating about which on top of the usual toxic crap found at a metal airliners crash site will probably cause a few more deaths in years to come. I really dislike the use of Carbon fibre composites, Once its in a resin build up you cant just recycle it like aluminium...will be the next century's Asbestos IMO, horrible stuff
  18. About time they stuck a turbine on it. If they can sell it for less than a comparably outfitted Kodiak I reckon it would do well
  19. They re-introduced Benzene?, isnt that stuff about as nasty as TEL?
  20. I'm sure they are great to fly but they hit it hard with the ugly stick (I can attest it looks no better in the flesh) Shame as the original was such a looker
  21. This one of those 'maybe' matters rather than a certainty, Shirley? Worth looking in to when training, I'll admit it was not on mind at all when I learnt
  22. AFAIK anaphylactic reactions come on very quickly, I'm sensitive to Bee stings though not to the extent of anaphylactic shock and the sting site starts swelling almost immediately. It's a shame as I enjoyed my short time keeping Bees
  23. I bought a TY91 transceiver and TT21 transponder about 10 years ago, since then i've changed aircraft twice and both times removed the trig units from the aircraft before sale, so i could fit them to my next aircraft (I now have a spare of each as the Nynja I have now already had trig units fitted when I bought it) They just work, the head units could be improved in the area of usability perhaps but they are reliable and the built in intercom functions well. Customer service has been first class, though I've had no faults I did send the radio back to trig for a firmware update and this was done free of charge with the units being returned in new original packaging as I had thrown the originals away years back.
  24. Skyecho is rather odd in its charging requirements. There is a very full thread on Charging in the Flyer Forum here: https://forums.flyer.co.uk/viewtopic.php?f=1&t=119153&hilit=sky+echo+Charging It's long but don't skip this post in particular: https://forums.flyer.co.uk/viewtopic.php?p=1864496#p1864496
  25. My Carmo install goes through master switch and fuse to battery. I didnt pay attention to grounding the case as I assumed it was not actually electrically connected to any internal components but was merely a heatsink. Maybe I should go back on that? I suppose checking for continuity between the negative wire from the regu and the case would confirm whether or not grounding the case provides any purpose electrically for the carmo?
