  1. Is it the same as this problem? There's a suggested solution in the last post in that thread. Welcome aboard. Jonathan Edited by - Jonathan Kay on 20 Dec 2012 08:49:39
  2. Thanks for the emails so far. Any more who ordered before 9 August? Jonathan
  3. *arrowup* *arrowup*That sounds better than my guess. Jonathan
  4. Quoting Gavin H: May be a stupid question but what does the % stand for or signify? (Just curious as I'm sure it has no bearing on identification...)Steering ratio, Wikipedia article... unless it has some special meaning in the world of 7s... Jonathan
  5. My first thoughts were also mechanical, but involved Lego Technic or Meccano. Bri's solution already beats that. If you want an electronic solution: What resistance does your controller want to see for no power, and what resistance for full power? I'm thinking of either: * A potentiometer that gives the required resistance for full power at 1/6 of it's travel, or * Some sort of passive voltage divider. (Wheatstone bridges for fuel senders discussed in this thread.) Jonathan Edited by - Jonathan Kay on 18 Dec 2012 21:18:41
  6. Quoting Piers7: AFAIK the standard rack is 1.9 turns lock to lock and the 22% rack is 1.7.Jonathan
  7. What's the voltage immediately after it's charged and the charger is disconnected? What's the voltage as you try and start? When you've got those figures have a look at this thread. Jonathan
  8. What sort of charger? There are reports that conditioning chargers may not be able to charge very flat batteries where traditional chargers (or the alternator) can. Haven't experienced that personally. Jonathan
  9. Purchase and shipping for 75 was $747 on 11//11/2012, which I make £477 Import duty was £48.35 + £68.73 Envelope £0.24 Postage £2.20 I think that's £10.36 each to you. I've never done this before so please could you advise on the following proposal: * I'll initially deal with all those who asked for one in this thread before 9 August 2012. When that's done I'll start on the ones asked after that. I bought a lot more than were asked for. * I'd prefer payment by BACS but cheques would be OK * For those before 9 August 2012 you confirm by BlatMail and tell me your address * I respond with the BACS details * You transfer the money * I send it when the money has transferred They're in South Oxfordshire. If anyone (who asked for one before 9 August 2012) wants to come and get one, or or pick up a batch for a group that's fine. Jonathan
  10. Thread threads: 1 2 You'll be fine. Jonathan
  11. I am now the proud, but, I hope, temporary, owner of 75 of them. I'll look into how to deliver them, then tell everyone the cost. No need for anyone else to do anything just yet. Off to a pantomime rehearsal. Jonathan
  12. Top Gun... antitallness is a big asset in high-acceleration conditions. Stops it taking your blood awaaaaaay.. Jonathan
  13. The Marcos 1800 certainly had that. I vaguely recall Setright discussing it. He was TALL. Jonathan
  14. If your need is the usual one: one 7 and stays on it all the time, then the cheaper one is fine, as long as it matches your battery capacity. The Accumate may be a bit cheaper and is also fine. Jonathan
  15. I've never been so insulted. 5' 7"? I'm 5' 7.5"! :-) Don't know about ACBC but Jackie Stewart is 5' 3", and I think Surteees, Prost and Senna were about that size. Mario Andretti 5' 4". At this point, according to BlatChat byelaw 147, I am legally required to quote Napoleon*, at least according to Time Bandits: Alexander the Great, five feet exactly. Isn't that incredible? Alexander the Great, whose empire stretched from India to Hungary, one inch shorter than me. Oliver Cromwell, the only man with any guts in British history, not a big man at all. Louis Quatorze, five foot two half. Charlemagne, dumpy little five-footer. He's quite a little chap. Attila the Hun, five foot one half. Cyrano de Bergerac, five foot three half. Tamerlane the Great, four foot nine and three quarters.I think I've only once been checked to be short enough for something: selection for RAF Flying Scholarships. There was a sort of seat and a collection of wedges they pushed against you, with lines they all had to clear. It's a big advantage on cheap flights, but having a 5' 2" daughter with you is even better. She can curl up sideways and you get two lots of legroom. Jonathan * I know, I know. And about Nelson.

  16. I'm 5' 7.5", my daughter is 5' 2". She can drive the 7 comfortably with the right cushions in place below and behind and the (standard, not Tillett) seat right forward. Jonathan
  17. Similarly... can you plumb the matrix back in while bypassing the bypass valve? Does it then allow flow? Jonathan Edited by - Jonathan Kay on 3 Dec 2012 17:37:17
  18. I think you'll be fine with any of several coolant options, which is why this has never been resolved. Good advice on retightening. I don't understand why people have such different experiences of this. I used silicone spray on the clips on my silicone hoses (from Classic Silicon Hoses) and none of them have needed retightening. We've had a recent discussion about carbon monoxide. Here's the seasonal reminder to be careful with ethylene glycol and methanol. And especially careful about where you store it and what you store it in. Jonathan Edited by - Jonathan Kay on 14 Nov 2012 15:45:11
  19. I've heard it mentioned, and there is at least one comment in the archives. I think it's because with some combinations of wheels, tyres and suspension the turning cycle wing fouls the bodywork and this limits the lock you can apply. Jonathan
  20. Lots in the archives on this, including: 1 2 3 4 (Last week we taught our medical students about the toxicity of ethylene glycol and methanol.) Jonathan
  21. Well, that's the answer: the breve doesn't survive BC at all. It's strange when that happens because it looked fine as I entered it. Jonathan
  22. Coandă , but I'm just wondering if that breve on the last letter will survive BC rendering. I think there was a thread about how to explain lift on aerofoils, which included a discussion about how much the Coandă effect contributed. Jonathan
