  1. You'll lose your car licence doing that. Nev
  2. Control system failures would be the thing to avoid. Redundancy in the Pitch axis is Necessary. Attention to throttle linkage and flap asymmetry' You need built in inspection panels. Structural inadequacies will show up as the Plane ages at stress and corrosion points. Bad build or design will concentrate stress at specific places. Every rivet is there for a reason. One not done right will put extra load on others Nev
  3. Even though I'm woodwork trained A wooden plane wouldn't be my first choice, Fabric covered steel tube OK watch for just in older examples.. Al sheet ok Particularly the RV as the holes are so accurate you don't need Jigs. IF you build something YOU know how well it's done and if you have doubts, check with experts before Proceeding.. Nev
  4. Lots of builders essentially cease flying when they are building due to Time and Money issues. An owner built Plane is More of an unknown that a certified one is and generally harder to fly. Small planes are more touchy than Larger and heavier ones are. Nev
  5. I'm sure it would be replaced. . I don't believe I'm overcritical of Rotax's. It's that some people can't admit they have any things that gave to be checked and that's not so. Anyhow stop playing the Man. It's not the way to discuss things, unless you lack any other argument.. Nev
  6. If you read what I say carefully you will understand better the Points I'm making . It's a completely different concept in EVERY way Nev
  7. I don't believe that kg. re the aircraft quality. the training killed them not the Planes Minimum control speeds. Nev
  8. Moneybox,You have just done a great job for the Critics of our Movement. When you build a plane for yourself. You have a special interest, because your LIFE depends on hew well you do it, and IF you are NOT sure you FIND out.. Nev
  9. What other small show has even attempted such a formidable Project.? It's a very complex engine and the Maker has no control over the installation. I don't agree with the reduction gear use of Nitriding but Case hardening would cause more warping. . Also you cannot machine Parts oval, easily. I haven't met Many Jet Captains who work on Motors or know a lot about them. They are spoiled as far as Maintenance goes and never get their Hands dirty on the Job these days so I wouldn't see that qualiication in this case as Meaning much.. It's also very likely he got off on the wrong foot early in the Game. Early in the Production of these Motors I visited the Factory twice and say good on them for even trying to do it.. I doubt they have Made much money from it, or ever will. Nev
  10. While it's a commendable Idea, It Can't be the way to achieve the Ultimate Build quality. IF you wanted to train people you'd do it on disposable little exercises first and weed out the Notably less skilled . beforehand. Nev
  11. Plenty of stuff on Line showing the Guts of the engines The later cast heads look fine by Me. Nev
  12. To many "emotive " words to take as a worthy engineering analysis. Engineers don't talk like that. Obviously intending to Imply the worst about the Engine. and the builders abilities.. Nev
  13. It's a big and sometimes deep, Ocean. There has to be a limit on what amount of effort is expended. Nev
  14. They are Not crooks and are trying hard to build a special type of Motor. . Nev
  15. I don't think Verner has made the distance, unfortunately like some many others, including the "D" Motor. which is didn't think would either. . Early Gnome and Rhone Motors have very low hours before they Needed routine Maintenance and they Only turn a LARGE Prop at about 1200 RPM with a Lot of gyroscopic effects and a high usage rate of CASTOR oil which ends up all over the Pilot.. I'd like to see a bulkier and bigger dia Prop on that Motor and reduce all possible drag Like the dummy Machine guns for Instance. Jacko's Sopwith flew fine. I can't recall what engine was in it. The NZ stuff, Like always will be a well done thing .I've seen what they do and they punch well above their Weight in these matters. Nev
  16. Women's Labour was used on a lot of WW2 aircraft in the USA. Douglas Aircraft had a Good Build Quality. In fact I've never heard any criticisms of any of the Major US Builders. . As OT above correctly states the Bristols mentioned were not Perfect that were Built here at GAF (I think) I knew a Bloke that worked there (now deceased. but he Made over 100 years) who was disappointed, however we did manage a lot with what we had it must be said. They were desperate times. . The Liberators were not a good design with handling and structural faults but were Mass produced unmodified for ease of servicing and training.. Consolidated Vultee Corp Built Catalina's.. In Australia Cabinet Makers built Mosquitoes. One of my Wood work Lecturers at Tighe's Hill Tech Did that. Claude Lamb I think his Name was... Nev
  17. Negative If the Rego on the tail is any Indication. Nev
  18. Self discipline makes old Pilots possible. Nev
  19. That was an ANSETT DC4 out of Perth Fuel system issue.. Tell people to go away when you're doing important things and IF you HAVE to Leave Make a NOTE to your self about where you were at. Shift changes have been found to be an obvious potentially dangerous disconnect Tag things. Nev
  20. Too Many "Mays". Also keep it simple. Using coolant will slow engine warmup and perhaps also make it run too cool in already cold conditions and there's more than enough water and oil Pipes already. Any under cowl source is suspect to contamination Possibilities. You want something simple that is tried and tested and Proven to work.. Nev
  21. The shrouded exhaust pipe still needs air over it when the heater is NOT being used. Nev
  22. Is it really Necessary? The faster the oil drains, the better. How can the Original fail? I'd consider putting a Magnet in it, to catch ferrous metal bits, Nev
  23. There's the Aeroplane's stated limit and your Limit. Both may be questioned. A High Wing can generally do a higher X wind than a low wing.. Rudder size and effectiveness count also . Small Planes don't have the Inertia larger ones do, so the Kick straight has to be close to touch down but better to touch down slower and on the into wind wheel (still banked) and countering the cross wind helping prevent weather cocking into wind OR wind raising the upwind wing and putting a tri gear Plane on it's nose. Nev
  24. You're going around and around in circles and still no closer to fixing your Problem. After all this. are you NOW saying there's NO problem? Nev
