  1. It's no help to you Andy, but in a bizarre twist of fate, today I found a brand new glowplug washer on the floor. I lost it months ago and after I dropped it and then just couldn't find it. During a general "tidying up" today (when I wasn't looking for it) I found it. Shame I'm in France not round the corner from you. C'est la vie!
  2. Danny, I know these are not quite the same as your situation, but here are a couple if photos of how I added stabilising brackets to exhausts. Both are Saito engines and both are linked to the engine or the engine mount
  3. When I dropped my grandaughter off at her gymnastic club (which meets in a local school gymnasium) there was a skip outside as building work was going on. In the skip were some very large sheets of sundela - obviously from old notice boards. I put some of it in the back of the car and removed the old paper staples when I got back. Job's a good 'un!
  4. Probably little help to you at this moment but I have just measured the washer from a brand new unused OS F plug. O/D 8.3mm, I/D 6.4mm, thickness 0.7mm. 6.4mm is pretty much 1/4". Washers are often made to be an easy sliding fit over a bolt. So a nominal 1/4" washer is likely to be more than 6.4mm I/D.
  5. From watching on his YouTube channel it would appear that saving the tower would allow people to continue to fly rc models locally. Though I may be well be wrong. Also seems to be some "history" to this issue too.
  6. It looks like the Phil Ramsey kit to my eyes. But I never had one so I may well be wrong!
  7. Not quite the answer to the original question, but... I had a Flair scout triplane that flew OK on a first generation OS FS40 (not the Surpass) and a Flair Legionaire biplane with a Saito 45 using a 12.5 x 5 prop. I really don't see why the OS40 surpass wouldn't be OK in your Flair SE5A unless it ends up extremely heavy somehow.
  8. OK, update on availability: David is buying the roll of silver. Alan I have sent you a pm regarding the red.
  9. Orange Solartex now sold too. Just the 5metre roll of silver left now.
  10. Sorry, the red solartex went straight away! Only the silver and orange left now.
  11. For sale: Unstarted 5m roll Silver Satin Solartex. In original sealed wrapping with instructions. £49 Unstarted 2m roll of Red Solartex. In original sealed wrapping with instructions. £19 Started roll of Orange Solartex. 4.5m left from 10m roll. £40 With instruction leaflet. £100 for all 3 rolls Collect from Canterbury or could post
  12. Not sure if this helps, but I built a 62" span Doublet twin designed by Denis Tapsfield . That was quite adequately powered by 2 HB20 engines. So maybe 2 OS20 engines would be enough for your 60" model?
  13. I always have my flaps on a slider, but don't use servo slow. That way you can control the speed of deployment with your finger - as fast or slow as you want or need. Works for me, but probably won't suit everyone.
  14. I agree that the silver finish looks much better than the camouflaged version. Silver Chipmunks from RAF Manston used to fly over my house all the time when I was a lad. Never saw a camouflaged one though!
  15. Taken on Wednesday after some more successful flights.
  16. You should try something new and build an EDF. So do the TSR2!
  17. Firstly, there are notches in the upper bracket that locate over the oleo retaining screws. Second I will drill the brackets and oleo to take small self tapping screws to fix them. Or I could just epoxy the brackets to the legs.
  18. Made up some brackets to secure the u/c doors to the oleo legs. The items supplied on the kit were only suitable for piano wire uc legs.
  19. Maybe OS use Japanese Industry Standard. http://www.motorcycle.com/blog/wp-content/uploads/2017/10/101617-japanese-screwdrivers-JIS-vs-Phillips-633x490.jpg Looking at a JIS tool next to a regular Phillips screwdriver, most people are hard-pressed to tell the differences, but they are definitely there. Ninety-percent of the time, a regular Phillips will work on a JIS screw; but it’s that other 10% that gets us swearing, then throwing things – those tight screws holding on your carburetor float bowls being particularly devilish once they’re past about two decades of non-removal. That’s when the right tool can make all the difference. The right tool is a JIS screwdriver, which just fits better in a JIS screwhead and is designed to let you apply more torque than a Phillips driver. I use heat and WD40 to help get "difficult" sews out. And I never use fuel containing castor oil!
  20. Belt and braces myself. I drill and tap GF/plastic engine mounts and use cap head hex socket screws into the tapped holes with nyloc nuts underneath as well. Then the bolts never come loose!
  21. The model is nearly ready to test. Does anyone who has built and flown one of these have any advice on whether the throws and CG in the manual are accurate. If not what did you end up using?
  22. Indeed, it's only the one page on this site and it doesn't happen on other sites either.
