scratch built 7m ASH 31

Hi, I started this about 6 weeks ago but it has been on hold. I am not planing to do one of my fast builds as I have a PT ASW 20 to do as well. I needed to start this so I can get over the fox build. I built a 5m ASH 31 about 3 years ago. It was OK but I wish I had made it in 1/3 scale. The fuz foam plug has been shaped but not filled and sanded plus the blue foam wing cores have been cut. I will post some more when more has been done.

Why the blue foam for the wings Roo? Is it just the obvious thing that it is stronger than EPS??

It makes a more accurate cut plus it is stronger

Started to make the cockpit tray. Pvc foam sheet I had left from sailboard building from the 90s. This is perfect for making trays place it on the cockpit opening lay a heavy weight on it and then heat gun it and it will follow the shape of the cockpit. Finished off with blue foam. Will glass with glass cloth and carbon.

Thats looking great Roo. Can you also make them in red. :lol:

I think at a later date many modelers would like a step by step instructional thread on the highs and lows of pulling your own canopies.

Roo, well done this build is turning into a lovely model. The added bonus is you will end up with a model with a superb flight performance at a fraction of the cost of a European glass ship. Regards John.

May I ask what Vinyl you use Roo, and where do you get it from. Reason for asking is I have a refurbished Wik Astir, the wings of which need re-covering and I am reluctant to spray them as I don't think the paint will adhere well to the old epoxy painted surface which was peeling all along the leading edge and required a lot of restoration.
Thanks
Colin.

I get it from zoom signs on eBay for £9 for 5m or £17 for 10m.

Really appreciate the response.
I’ll order 10m and give vinyl a go.

Love your models by the way.

Last post before maiden but do not know when looking like it might be next year. This is the last big build I am doing running out of space and I am now fed up with building. But I will be hopefully doing a pat teakle glider build sometime.

Man that looks good! You must be proud, although I can imagine why you’re exhausted.

Good luck with the maiden flight, whenever that might be...
