They use it to insulate interiors in some applications.

I have several ready made wing bags (I looked at how they were made). And I never had any scratches from the foil. Then again, I only have scale airplanes with painted surfaces if that makes any difference? I couldn't transport or store these models assembled as they are too big.... The Bestmann is 255 cm span. My WW1 planes are all between 160-240 cm span. The control horn problem is real on some models. On my FW190, I use a sleeve made from fleece with a piece of Velcro that I wrap around where the horns are. On my other planes, they don't protrude as much.

The biggest risk with storing and transporting our aircraft is that you accidentally damage them. The ever dreaded hangar rash .... Wings, stab's and propellers are the most vulnerable. Ready-made wing bags are good, but they don't fit many models. Alternatively, custom-made bags, but those are quite costly.... I wanted to try making my own. A trip to my local automotive supplier later, I had two 5x1 meter rolls of foil thermo mat. I found edge ribbons to use. I measured the wings with a couple of centimeters extra and cut the foil to size. I use sewing pins on the edge to be sewn on (the sewing class in school was useful after all...). I'll sew it together tomorrow and put Velcro to close it. It looks good so far. And how much does it cost? Around £15 a pair.

Nice, where did you set your C of G?

They do attract red kites! I flew together with one for a very long time today. The C of G is very forward in the instructions. 60 mm. I moved it to 80 mm, and I can move it further back with no problems. It flies very good and loops with no issues at all. It flies good at 25% throttle. The 2200 mAh 3S Li-Po is more than enough... I will try a 1300 3S pack.

I painted the eagle so it's ready for today's excursion. It looks way better when it's brown instead of purple. I'm really curious to see how it flies.

During my convalescence after an eye surgery, I had to find something fun to do. Fortunately I had ordered a DW Eagle (the 1450 mm wingspan version). I started building it at lunchtime today and was finished this evening. A very nice kit. (Although they seem to have missed when printing it that an eagle should be brown, not purple...). Nothing that can't be fixed with a little painting though. It will be flown with a 3S 2200mah LiPo. Now I hope for a quick recovery and gentle winds.

The LeRhone dummy engine is finished. I just need to add a few more oil drippings, but I'll do that when it's mounted in the airplane..

I have CAD designed the windshield frame and the cocking handle for the machine gun. 2.5 hours in the printer. Printed in tough resin. I just got a new kind of resin that should be even more durable. I'll print another one tomorrow in the new material.

Here is a better comparison with the J Perkins version and the resin printed one. Lots of differences.

My home-printed Vickers machine gun is now painted with Tamiya Nato black, Vallejo Black and some brown tones for the rust. My prototype is in a museum and has some rust.

The STL might be tricky as I redid it in fusion and then exported it to Photon software. I can check to see how to share it as a STL format file.

The machine gun that came with Reeves' 1/4 scale Pup kit wasn't that great. Printed in PLA with lots of lines and rather crude. I 3D printed my own in tough resin. Found a perfectly good CAD model online that I modified a bit in Fusion. A little paint on it will make it look great.

Yes, but actually no.... It is designed for a 120-150 four stroke engine, the 120 r3 isn't that strong. Recommended prop on the 120r3 is a 14x5. My 33r3 spins a 20x8. The cowl is 10", so a 14" prop won't stick out much, and that also effects the performance.
