Ah, points taken gentlemen. Anyone who read my post, please ignore it!!!!!!!!! 8lbs ?! That is heavy for a foamie. I did check out a thread on RC Groups, but didn't spot any talk about the nature of the foam. My only experience with mylar hinges was nearly 4 years ago on an Easy Pigeon glider. They weren't pre-installed and I didn't know what they were, so I used reinforcing tape.

HI Geo, Have the hinges come off? Or are you just reinforcing them from new? Whatever the reason, you'll need a foam safe glue. UhU POR or UhU Creative should be fine. Always test a tiny bit of the glue adhesive somewhere inconspicuous, like inside the fuselage. If the hinge is detached, I would use a thin bead of UHU along both pieces right at the join, allowed to dry, then slide the pieces together with both parts resting on a flat piece of cardboard/balsa/ply/whatever, that way you have the best chance of good alignment. If you mess up, just cut it away and start again. ;¬ Hot glue would also work. For that, I would assemble the hinge with masking tape on one side, then pivot the hinge open a little, towards the masking taped side, run a quick bead of hot glue n there and, before the glue hardens, wipe most of it away with the corner of a piece of scrap foam. You can see the method at 7:10 in this video https://www.youtube.com/watch?v=DnJ85Sz1iak :¬ Hope that helps.

I'd say B will sting someone.

Use acrylic paint for absolute safety. But you could use non foam safe sprays if you keep the can 12 inches or more away from the model. And pizza base or other food packaging foam makes a reasonable quick fix. Don't forget to use foam safe glue , or hot glue.

I would say it still needs to be cheap due to it's age. But you haven't mentioned the make or model or the price. Those are always to be considered when the actual value of a vehicle is in question.

I'm not convinced by that video to be honest. The concept needs to be proven on video. In other words, let's see a deliberate thermal runaway in the Bat-Safe, Batman!!

Posted by Phil May on 24/05/2017 12:00:34: Cheaper a Wilkes. 8x4 2mm thick, a fiver WoW! I like the sound of that Phil! I buy stuff in Wikes all the time but must have missed it. I can't find it on their website, I've searched for coroplast, corplast, corrugated plastic, plastic sheet, insulation, so far. What do they call it? . Ah! Found it! Proplex protection sheet.  Hehe! It's actually £3.95 !!!!!!!! Edited By Chuck Plains on 25/05/2017 19:54:38

I have not made any wing bags or travel boxes so far, but allow me to recommend trio_floor_protection_uk on Ebay I got two sheets in 2015 and their price doesn't seem to have changed £11.50 for a 2mm sheet 8x4 ft (non fire rated). Delivery is free and it comes rolled up. Hmm, as I make more wings, I guess I'll have to start protecting them from each other and what have you. Heh, I've just installed some superglue packaging blisters over my servo arms for streamlining and protection. But a long bag or box does seem in order in the long run.

Here's the flying wing CG calculator I use. **LINK** And here's my previous result for my 55 degree delta. It's great, because it changes shape to match your wing after you click the update button! Oh yes, when you open that page click on "Extended version" at the bottom, it may be of more use Edited By Chuck Plains on 14/05/2017 19:06:28

Doh! It was a bit too breezy to try it today. Gusting to 20mph is asking a lot for a 400g 2 chan with a 20 year old balsa wing, even with our club safety officer offering to maiden it. So we left it for now. I shall reinstall the tow hook and attempt to bungee it if the wind drops one evening this week. As to how to disconnect, you just give it some good up elevator and the velcro should pull apart. Even our tug pilot had heard of this method, though he'd never tried it. Heh, better luck next time I guess. Ahh, the Bird Of Time! Is that the 3mtr one? Such a beautiful shape. Definitely a bird I am considering purchasing, despite telling myself I have to make everything on the cheap. Cheep cheep!

I have a 70mm EDF waiting in the wings, (haha! pun intended! ) The plan is to attach it t oa "Zephyr type flying wing. And I had already determined that I should knock up a nozzle type outlet for it, so that I can easily adjust the TA after fixing the housing firmly in place. My idea is to use a section of plastic or foam picnic cup. Too big for indoor though. Ahem.

      Scratch built glider to give new life to old wings. Yes, these Precedent Hi Fly wings will, hopefully, start a new life with my new pod and boom thingy. What? Crashed into a tree already??????? See how tough this glider is? It felled a tree and chopped it to pieces!     The fuselage is 4mm balsa covered with reinforcing tape at the front, boom is lightweight wrapped carbon fishing rod section, and the tail and tail plane are 4.5mm 'stripped' art board foam. (Very much like Depron) I'll be honest and say I haven't flown it properly yet. As evidenced by the rather wrinkled nose cone. Hopefully we will see an improved performance at Devon Glider Day tomorrow!   Edited By Chuck Plains on 13/05/2017 14:50:16

Yeap, I've removed the hook for now. My cheap bungee from Hobbyking really didn't get the thing up all that high, though I may be doing something wrong. So the tow pad of velcro loops is positioned on the belly and directly behind the (now slightly squashed looking) foam nose cone. I've put 2 pieces x 50mm x 20mm wide of it on there, just to give a bit of choice. But the attachment for the line is just a short piece of nylon cord looped through a 30mm piece of 'hooks' folded in half and stitched together. So the actual attachment will only be about 15mm x 20mm. I'll be asking the tug pilot to give us a 30 degree-ish climb out and see what happens. Oh, plus the first tugged flight will be with an experienced pilot, if I can find someone willing to help. I'm still chucking it to try and work out this new 2 channel style flying. Doing some more test chucks this pm, before Devon Glider Day tomorrow. WSW and SW winds will make it a perfect day.

I used my bungee this evening after a few chucks. It works, but I'm not too happy with the glider now. I'll be posting about that elsewhere.

That's a good price Sir Braddok! Though I don't use that size, I mostly use size64 (3.5" x 1/4". I would have recommended Staples Office Warehouse, but their prices have sprinted up recently. And even Ebay isn't that cheap.

Posted by PatMc on 05/05/2017 20:56:20: I convert any rubber band fixed wing designs to screw fixture before I build whenever I can. Rubber fixed wings is a free flight throwback unnecessary with virtualy all RC models. Why unnecessary? I've converted most of my RC planes to rubber band wing fixing.
