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!!

It only says the pilot was injured.

Cheaper a Wilkes.
8x4 2mm thick, a fiverWoW! 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 !!!!!!!!

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.
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

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!

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.

I don't think it is a good idea to aerotow using any form of belly hook.
As above - aerotow releases need to be in the nose or very close to it on the underside.
Again, check out Speedster's video.

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.

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.

Yes, a tug tow is the last stressful for the glider. Couldn't possibly use that Velcro if it was otherwise.
-
Facepalm!
I've watched your Towing 2x Alulas video before and never mentally clicked that you mentioned the velcro back then!
I might suggest it for the Devon Glider Day later in the year.
-
WoW! Thanks for that Speedster!! Velcro! Why didn't I think of that? DOH!!!
I watch a lot of your videos by the way, using both of my YT channels (wordeet is my oldest one)

What about a pylon mounted motor ?
Heh, I already have a 'firewall' built in and just added a foam nosecone in front of it. So a motor was always in the background for this one.
But to truly answer your question. I detest the sight of motor pylons. To me, they're about as attractive as an armchair on an Albatross.
-
I haven't 'binned' a plane yet. Though I do have one or two that, well, you know. But I can't, not even that tiny 12" glider I made from a plan, but accidentally put a bag full of shopping down on. I'll try to recycle each piece one way or another, one day or another.
-
Thanx for the replies fellas.
It's a 2 channel, no ailerons. I've already emailed asking if I can set up a bungee for the Devon Glider Day on the 14th. It's originally stated as aero tow or electric powered only.
-
Aw man! That's sad news. But I'll have a dekko and see if there's anything I might need for later, even if I don't need it now.
-
I've recently finished a basic pod and boom fuselage, so that I can get an old set of Precedent Hi Fly wings up in the air.
Heh, but I built it without considering that the club I go to rarely has a bungee set up these days.
So, the question in the title stands. Can it or can it not be towed up using the belly hook?

No plans for me thanks.
I think that's because I work to drawings every day and the only chance I get to be creative is when something goes wrong.
Everything comes off the top of my head so to speak. Though I do occasionally search through what's available on aerofred.com for clues on how to do something I'm not sure about. Even then I may ignore what I've seen.
Very low mileage older car - should I be suspicious?

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.
