  1. I hate to mention it, but I said the same in post 3, above - also because of the problem someone had a week or so ago 😛 It wouldn't have crossed my mind either, otherwise. Of course, I would never, ever, dream of blowing my own trumpet.
  2. Also, make sure you connect the BEC lead (the one from the esc to the receiver with a servo-type connector) to the throttle channel or the motor certainly won't run.
  3. IIRC Modelfixings sell lh thread 3mm rod. I've always called 'turnbuckles', 'bottle screws' when I used them for dinghy mast stay adjustment. I think thy're the same thing.
  4. South Yorkshire has a history of lighter than air aircraft. The R100 was built in Howden a few miles east of Doncaster on the north bank of the Humber. It was much more successful than the R101, perhaps because it was designed by Barnes-Wallis and part-time novelist Neville Shute Norway. btw I know Howden is in East Yorkshire but it's still geographically in the southern part of the county 🙂 It sounds an interesting project. I hope that it's both successful and doesn't affect the model club.
  5. I'm pretty sure nail varnish remover is acetone, which works to soften Cyano, too.
  6. Of all the biplanes I have and have had, those with ailerons on both wings moved them the same top and bottom. Both my 58" ws DBS&S Moths (Cirrus- as in my logo - and Tiger) have double the movement up compared with down and both can be flown without using the rudder, but I usually do use it. I think I'd go for both the same for a start, but with differential. Why would you want them to be different? Just curious, not critical.
  7. The one in the Formosa which I was gifted by one of the club's best builders. I got it with motor attached and never took the cowl off to check because it just worked (and Jim isn't a dummy as either builder or flyer) until it exited through the cowl. Sadlly, cowls are not available as spares, so I fly it cowlless with a different motor. My dad taught me that grub screws in this sort of application should be at right angles to each other rather than 180 deg for the reason Simon made.
  8. I think they be the ones like this : Which, as Simon says, can let go unexpectedly. Guess what happened here 🙂 I never found the motor but made a greaser dead stick landing.
  9. Fixed the damaged wing tip this evening. Before: ... and after. Not perfect but once covered it'll not be seen. Rather than 3mm birch ply I used what's becoming a favourite material, 3mm Liteply The hard bit will be to cover the bit next to the aileron end (which is still attached - for some reason the other one pulled out the hinges), but, no doubt, it'll go in somehow. It's radio/servo installation and covering the repairs and the new fuselage, mostly to do. Perhaps I should wash off some mud, too.

    DX8 v NX8 ?

    I suppose we are. In an ideal world, we'd all have just one model and fly that until it crashed or wore out ... or would we? 🤣
  11. I've been beavering away with my new Wot 4 Mk2 fuselage and getting near to completion. The wing fits OK and the tail components are glued in. The tailplane is more or less parallel to the wing (more 'more' than less!) and its incidence relative to the wing is 1 deg positive, which is the same as an old Wot 4 Mk 3 I dragged out the loft to take to a swap meet on Sunday (it didn't sell! - Now on eBay) The fuselage seems to be fairly light - hopefully not at the expense of strength. The sides are 3mm balsa and the doublers 3mm Liteply, lightened further, as can be seen in the pictures. The battery tray has been extended from my original because I had to put weight on the tail when the battery couldn't be slid further back. The battery position will be fixed with foam pieces at the front and back (the front to protect from protruding motor-mount bolts. Here's the area under the wing, which will be home to the elevator and rudder servos - and possibly the receiver. The under side will be sheeted once the closed loop rudder and elevator push rod are installed Onwards and (hopefully) upwards. The now no longer ARTF Wot 4 will fly again!
  12. It's quite a tough climb on a bike. I rode a hill climb there a good few years ago when we were staying at the YHA nearby. When I had the accident that damaged my spine, I got out on my bike as much as possible. Glad you're making progress, Matty.
  13. I'm not sure how useful static thrust measurement is. I did experiments like this when I was trying to get electric models to fly with NiCads and cheap brushed motors, using a spring balance to make the measurements but once the model is moving through the air all the static measurements are moot.
  14. I'm glad. Just think about how often many of us have made similar mistakes in a build. Making 2 r/h fuselage sides is really annoying but insignificant compared to having the wrong knee replaced, or, in my case, having the good eye operated on rather than the bad one.
  15. Probably the reason everyone I dealt with when I had my cataract operation a few months ago asked what my birthday was - however, I was disappointed that I got no extra cards on my birthday in January.
