Funny, Mine was not too sensitive in the stall.. Possibly I didn't try to slow it down too much.

" It doesn't look too tricky and it's a lot stiffer than other stuff I've covered with the household iron"

Spoon handles can be warmed up on the iron to reach small corners.

As can butter knife blades.

Etc.

No reason to fight with the clothes iron if you can avoid doing so!

img_20190213_203402.jpgMade a couple of canopies today. Not sure which one I prefer yet. Aldi orange squash and Aldi fresh orange bottles. The squash bottle is framed using strips cut from a can discarded by one of the local alky's img_20190213_203311.jpg

Did youknow that if you carve a pattern from balsa or something fairly solid you can jam it into the bottle. applu heat and the bottle will shrink over the pattern.

Now that opens up many possibilities. Thanks.

Just got a proper sealing iron. Easier to handle than hers. So this is the result, tail ready to fit

Thanks. It's Hobby King film. A swine to separate from the backing but so far, no white lines that are often warned about

Peter, I have a question about the plan and the article if I may. In the article you mention 1/2" aileron tips but no mention of them in the plans. How much of the tips are shaped from balsa? Do I change direction of the grain in relation to the TE stock? Are they shaped the match aileron profile?

Basically it refers to the wing tips, on the perspective drawing it shows the 1/2" sheet tips.

If you look at that drawing you will see that the ailerons continue right to the wing tip in one piece.

Hope that helps

The canopy was formed over a balsa die, the donor plastic is courtesy of a Frosty Jack cider bottle (left by one of numerous alcy's in the area)img_20190310_210143.jpg

Looking good, MikeE, like the canopy

I bought a part built at last year's swapmeet, and coincidentally have just recently started working on it

There's a way to go yet, it will be OS 30 two stroke powered - and probably windscreen only !

THat looks very neat.

Just one thought. That leading edge looks very sharp. Be readfy for a sudden stall without warning.The blunt rounded LE is much more forgiving.

Of course I may be wrong and it is just the way the light is falling.

I like the bue canopy.

Hmm. Right well I used LE stock and have only smoothed it. Hope it's okay, I still have to learn to fly (with another plane or two) and looks like I have lots to learn about building too.

Hello Mike

I am an Oodalally builder but have switched over to resurrecting a model yacht I built 50 years ago. Your post has given me the urge to get on and finish it along with the Grumpy Tigercub which uses the Oodalally wing but designed as a twin.

You have made a nice job of the canopy. I have a balsa plug ready made for mine but struggling to find a big enough bottle. Maybe I will have to stretch one first.

Good luck with the maiden.

Hi Levanter,

I made several canopies before settling on this one and found that I had to stuff the plug in to the bottle the opposite way to what I thought was logical. The rear of the canopy plug goes in the bottle towards the neck. Once the initial plug was carved I added about 3/4" to the rear end then shaped to match, this gave me plenty to cut off whilst removing the wrinkles.
I tried Aldi and Lidl fruit juice bottles but the Frosty Jack cider turned out well

I have always found that lemonade bottles are good. They are clear but they do not have as many ribs as other bottles do. Most brands are the same from Schweppes to Co-Op ones

Perhaps a bit more 'rough and ready' but the replacement canopy for my Advance 25e, I have made from an Acetate sheet. Looks and works OK though.

Some of those without formed wrinkles and bumps look nice and smooth, just right for us but they have a vertical moulding seam. The shops own brand cola and lemonade bottles may be good for motor cowls they're so big
