  1. Looks good Manfred. After the umbilical connection, where do you plan to go next? Does this phase finish with the unpainted tank or should we expect you to move straight on to the orbiter?
  2. Maybe someone was thinking: "fast jets" "medium speed turbofans" "slow piston props" - but got bored before they finished the sweeping statement?
  3. To briefly put on a serious hat (and also acknowledge that I started this latest round of helicopter ribbing)- I'm completely with Crisp on this. I'd imagine that every fixed-wing instructor on the planet has told their student to take their hands of the controls whilst flying final to prove that their stress and over-control is making flying much harder than it actually is, but as Crisp indicates, this will only happen when the aircraft has been trimmed for the intended path. Most of these training aircraft are a bit rubbish for a decent pilot (think Steve, NOT me) as they are too stable to be chucked around the sky by someone who knows what they are doing. The price for helicopters being able to do what they do, is (entirely planned) instability; you can't take your hands off the controls. Doesn't stop them (well, some of them - let's not push it) being both immensely cool and rather beautiful. Normal service is now resumed: It's all black magic and sky hooks.
  4. I can never decide whether I prefer the digressions or the modelling on this thread. Don't know what I'll do if Steve ever finishes it; probably start learning lots about making Jaguars I suspect. Thanks Bill, Crisp etc - I needed something to smile at today.
  5. Is there a corresponding manual for helicopters? Their uncanny ability to get off the ground goes WAY beyond simple air and magic. Crisp has often patiently tried to dumb the subject down for us hard-of-thinking types, but I feel that a diagram like the above might really uncover the mysteries of a collective, swash plate etc.
  6. I'm sure it is - Edge just won't navigate there. Might be worth mentioning to your hosting provider.
  7. I'm getting a certificate error on that site Ron - which is a shame as I'd love to see your 935.
  8. You're way ahead of me. At one point this morning, I scribbled down something based on a Teleflex cable but your screw jacks have much more potential. You also put me on to @Jamie @ Sovereign Hobbies's amazing project - which means of course that you simply must have turning props as all the hard design & prototyping work has already been done (!). A little bit of code could have the engines starting in turn on your apron...
  9. I think the real jet pipe has a kink in it so it sits quite close to the airbrake jack. It can be a bit sooty inside so who's to know/complain if it has to sit a little high in the miniature version? I always figured they put that much solder on the roll so you can use plenty of it when you're learning. Otherwise, what would be the point of all those solder mats/sponges/syringes etc. that they sell? So don't get too good too quickly or you'll find you have far too much solder in the house; it'll probably go off. Nice strakes.
  10. Haven't really thought it through yet but was thinking of a bit of slightly springy wire or strip (e.g. from inside a tape measure) extending from the actuator to the tip of the ramp so it could both push and pull. Neither have i thought about the top door at all, or about how to work in some limit switches. Has to be possible though. Top door should drop under gravity, so the primary problem is lifting it. I wonder how the real thing works?
  11. Like Sithman, I was a little too quick to think of this as a fairly simple stack of cylinders and cones. Boy, have you proved me wrong. Fab model!
  12. Is there room for the linear actuator under the floor?
  13. Now that would be really impressive!!
  14. Turning props & lights would be really impressive. I read somewhere that the motors for the buzzers in mobile phones are good for this sort of thing - although 1:48 Hercules nacelles have probably got plenty of space for something larger. If you want to do fancy things with lights, I can recommend Arduino controllers as they're surprisingly easy to set up, so flashing strobes and switchable navigation/landing lights are eminently doable. Looking forward to watching this one progress.
  15. What dedication, and really impressive. Brings a whole new connotation to the phrase "scuttling off into the distance" though...
