  1. Nice job with the planking. It can be quite time consuming but ultimately satisfying. I had to plank the bow and stern of my Thames sailing barge hull. Then decked with a sheet of light ply with score lines for the deck planks I really must finish it some time but there's nowhere local to sail it. I bought the complete kit from Traplet with the CNC parts, 4 huge sheets of drawings and a DVD. As it turned out the hull formers were wrong and I had to bodge it to get the chine straight. The reimbursed me for the whole amount so it's just cost me the 3mm balsa for the sheeting. Sorry for the none aero modelling comment but sailing is really just 2D flying
  2. I have the Windsock data books for both the SE5a and Sopwith Pup and they have full colour pictures of the different schemes as well as some original monochrome prints. Apparently there's a method of scanning the grey scale and coming up with the original colour (and some WW1 types are very colourful). However, it's far from accurate and is, at best, an intelligent guess. In any case, who's to say all the (say) reds were exactly the same shade from batch to batch - even modern wallpaper varies - if you need to buy an extra roll it's likely to look different from the ones you bought at the start. So there's no real answer. The shade of PC10 you choose is as likely to be as authentic as the next person's. For what it's worth, I used Flair Spectrum PC10 on the Flair SE5a I built over 20 years ago. It looks all right to me if you ignore its general tattiness!
  3. The most amazing thing to me is seeing a Lazy Bee that looks in a worse state than mine!
  4. That looks pretty high up to me. Glad you got it back OK without injury. It was certainly a nice day today. Avice and I had a lovely walk in the morning and I noticed that there were no sheep in the field I occasionally fly from so I may venture out tomorrow. It's the cold hands that get me though despite heated mitts which don't seem to keep fingers warm.
  5. I started driving before motorways were built (and before any speed limits other than the 30 mph - which were usually actually 40 mph in practice). I was living/working in Welwyn Garden City when the M1 and M10 opened and there were almost more cars steaming on the hard shoulder than on the road itself I only had a motorcycle at the time (a BSA Golden Flash) and rarely used the motorways because it was so boring. How times have changed! When I have used a so-called smart motorway I avoid using the former hard shoulder simply because if there's an obstruction that's where it's most likely to be. Normally I use the clearest, most leftward lane and as often as possible lane 1 but having no hard shoulder on a fast multi-lane road makes me very nervous. I'm glad they've stopped adding to them and hope they reinstate the hard shoulder on the others.
  6. I have a copy of that photo on my workshop wall - I bought it when we visited Kitty Hawk in 1996. I think my wife and I are probably the only couple to ride a tandem up Kill Devil Hill to the Wright memorial - we probably weren't supposed to but there was no-one about. It's well worth a visit if you get the chance - it's very modest and run mostly by volunteers, which took me quite by surprise. The photograph was the first ever taken by the photographer using a camera set up by the brothers. Certainly no catapult was involved but there was a strong breeze which gave a fair bit of airspeed even before the taxi run.
  7. That's odd because I pass Stanford Hall on my way to Melton Mowbray to my brother's home (and Buckminster) and I'm sure that's where the VMCC used to have Founder's Day events but it's nearly 50 years ago so I could be confused (not for the first time!). It's much better displayed in the photo than it was when I saw it in quite a dark barn. I'm already depressed enough with my birthday coming up tomorrow Geoff
  8. In the USA they drive on the pavement Also what about parking on driveways and driving on parkways. Language is interesting, especially its variations. There used to be a full-size model of Percy Pilcher's hang glider at Stanford Hall near Loughborough. It's where he met his end doing a demonstration flight. It's very similar to the gliders the Wright brothers flew from Kill Devil Hill at Kitty Hawk so I guess that, whilst the Wrights were the first to fly a powered aircraft (a very short distance you can walk in a couple of minutes), all the early pioneers relied on the efforts and experiments of those who went before. Few (if any?) later designs used the canard design of the Wright Flyers and were quickly much more successful eg Bleriot's cross channel flight. There also used to be a vintage motor cycle museum there which is why I used to visit. Geoff
  9. Not the greatest start to 2022 for you, John. Get well soon. Pete, I've always been a bit wary of using wood threads for regular and frequent use (like wing attachment/removal) but perhaps I should try it. By 'thick' plywood I assume you mean 6 mm - or more? I like the threaded inserts sold by Modelfixings and I've used them a lot as they're neater than the more common T nuts. Geoff
  10. The thread pitch is very close to 6mm x 1.0mm but I guess 6mm is sufficiently less than 1/4" (6.35mm) so will be too loose. You could use steel 1/4" BSF, I guess, or replace the captive nuts. Geoff
  11. I think Cyclons are intended for float back up and to be charged from a constant voltage. That's how I charged mine and certainly didn't bother with a current limit. I was fortunate that I was able to use a bench power supply at work As RR writes, they're very robust.
  12. Did you measure the current draw? Cyclon batteries are very good but the last time I looked (some years ago) they were quite expensive. The 2.5AH ones are roughly the same size as D cells IIRC.
  13. I used to use 3 x 2,5AH Cyclon batteries in series fitted in a bidon to power my bike lights for my winter commutes. When I started aeromodelling after I retired I used one to power the glow plug on my trainer and never had a problem. They are incredibly powerful with a very low source resistance as Martin writes. I used to charge my bike battery at work and commandeered a bench power supply for the purpose. IIRC the 3 in series charged quickly with a constant 6.5v supply and lasted many winters
  14. One of my most treasured possessions is my Dad's penknife. The blades are all worn down through regular sharpening and he's the last person ever to sharpen it even though he died in 1991. He always said that it's blunt knives that do the most damage to fingers because a really sharp knife doesn't get deflected from its course. Having cut myself numerous times with brand-new scalpel 9a blades I'm not so sure he was right I had a chuckle over Zoe William's article myself over breakfast. It reminded of a time very long ago when the woman who served in our shop was preparing my tea, set out to open a tin of Spam that was slightly bulging - the rotting semi-fluid sprayed all over the kitchen and the smell was absolutely awful - it quite put me off my tea.
