  1. Despite the Aura and nostalgia with the RR Merlin it did have a few basic faults and did not have a very high TBO. In Most Countries it was never accepted on the Civil Register as a commercial powerplant. Magneto skew gear failure . Cam follower scuffing ( No rollers) and Auto Boost Control amongst other things . It's easy to cast Blame on restorers and I wouldn't take much notice of the "OLD GASKET" thing. There is some Good stuff on the skew gear on line. Nev
  2. Fortunately, we fly for a Multitude of reasons so DIFFERENT planes will appeal to different Aviators. There will never be a "One size fit's all". How a Plane penetrates rough air depends a lot on Wing Loading. IF you want to go Long distances safely and when you want to, Fly with Airlines. Don't try too hard to justify the Practical aspects of owning your type of Plane. Don't rush to buy one. The Longer you look around and experience things the Better your choice will be IF you decide to Buy.. It's NOT a Must do for every Pilot.. Nev
  3. Can I direct you to My Post just prior to your disaster, which you didn't reply to. Nev
  4. It's not only too much advance causing problems. It can be too hot a plug or an overheated exhaust valve or crook fuel or too much boost. I've never experienced it personally in any aircraft though I've had engine failures for other reasons. Most aero engines run fairly Low compression ratio's and have a limit on how long TO power can be used for. METO is MAX Except Take Off. With certified motors and good cowling and management I'd suggest it's not a Large issue. A richer Mixture can alleviate it. The damage is typically piston ring land breakage and Piston crown caving in. I've never seen that with an aero engine. Detonation is Hard on Motors. Any diesel added will surely kill a motor during take off It happened when Turbo charged Motors were Introduced. Some fuellers thought TURBO Meant Turbine. Nev
  5. The B727 was Underpowered sometimes slow to altitudes and IF you got slow it fell out of the sky on approach. Lots of FLAP and DRAG. Not a Beginners Plane. Designed to use shorter strips. . Lots of redundancy in the systems. keep engines spooled up below 3,000 ft .Very versatile, Powerful controls. 2 Yaw Dampers on the rudder. Lots of flap speeds and settings and 2 schedules depending on actual Weight. . Those Dreamliner Lovers Probably never got to fly the Douglas DC9. We called it the "Ducati of the Skies". Had little range. 3 Hours to empty. They are ALL PLANES to me. Nev
  6. Lean of Peak is not the way to go if you want engine reliability in the long term. AVGAS has 2 Octane ratings The higher One for RICH and the Other for LEAN, The BIG radials ran on avgas 130-145.There's one as 100-130. I doubt these days you can get the Higher ones at all. All those motors will have to run De-Rated. ( with Less Boost). The DC-6b Had an onboard Ignition analyser (under a hood) for the P&W R2800's for the Flight engineer to Monitor. The Constellation Often referred to as the Consternation and the Boeing strato Cruiser were Notorious for Engines being shut down in Flight. They were the Big Wrights which were also fitted to the Neptunes. Nev
  7. Maybe bright sunlight in the cockpit? What about the despatching engineer talking to the Pilot before the Plane is pushed back showing the gear pins and knowing the brakes are released. The baggage is often loaded right up till the Last Minute. Nev
  8. Money saving policies and accountant driven short cuts, outsourcing etc. The earlier 737s had rudder problems that lost a few Planes. I deliberately Avoided Piloting THAT plane though most of my time was on the B 727-276, Boeings stretched Trijet and a well constructed thing by Contrast. kgwilson covered it well. including the Engine Positioning. I'm OK with the Airbus A 320 although the cabin width is a Bit less for 6 seats abreast. It certainly has plenty of engine thrust. An easy winner in my books
  9. Debating is a contest, a Game that produces a Winner. The actual topic is not of much Import. Like A Pissing contest. A sensible discussion takes the Good and it can be built on, developed, clarified and explained . No one should be PERSONALLY attacked but what they Propose they need to be able to explain. Back it up. People say......... It seems........ I read it somewhere. Not good enough for Aviation. Nev Thanks SP. I needed that
  10. Apply that to your Own stuff. Be consistent. It's not quite How a Forum operates. Have YOU ever officially test flown anything? Nev
  11. You need function FIRST and form should FOLLOW it. Swept back rudders are a styling exercise unless it's High subsonic. Mooney never did it. and they are Slippery. Nev.
  12. The LATER ones. The entirely FLAT roofline had to go. Nev
  13. Don't bet on it. Nev
  14. The corrugations don't align with the Direction of the airflow unless it's a Co-incidence. . Be interesting to have actual L/D figures for the Plane. Nev
  15. Close Coupled Cowls on those 540s Can cook the engines. Cowl gills are Manually operated generally. Nev
  16. Few people will admit they Bought a LEMON. Most Planes are a good way of sending you Broke. Bad weather affects them all. NO plane LEARNS to fly. You always have to get it to go where you want it to. Autopilots have their OWN set of risks. You can't JUST leave them to it. Nev
  17. Detonation is not a problem generally when engines are operated at the recommended settings and correct fuel. That includes the CORRECT Heat range on the Spark plugs and Making sure they are correctly Tensioned. Observe CHT Limits Boost and Rpm combinations.. Nev
  18. That Price is cheap enough if it's what you want. A V belt derive is My preferred Method. The Quill drive is designed as a failure Point to protect the rest where it's direct. Nev
  19. Are you sure of what your Material IS? Nev
  20. Most earlier stuff was FLAT Perspex supported by a fairly strong frame on 3 sides.. Nev
  21. I Probably do much more searching than Most do and it's WHERE you search that gives the BEST results even IF it's not the answer you expected. The MIND doesn't live easily with unanswered questions so will often be comfortable with something convenient and not too challenging to their Current Mindset. Nev
  22. Many Installations will overheat the engines quickly without the Cowls in Place. Nev
  23. Might be per Hr or per flight. Most Robbo's are not static exhibits, and are relatively short flights. Nev
