Hi Everyone.
I have for some time had a book by Michael Johnson and Alan Austin titled "Paper Planes" with the subtitle "They Fly!"
I bought the book in a charity shop and one had been built and the next had been started but some parts were missing.
Have any of you heard of or tried this book ?
If so I would be glad of any help or advice you could give me. The one I have built so far flew very well but was fragile. The authors suggest designing your own reinforcement but I am not that good.
They are good looking models and I would like to build them better.
Hoping for help.
Liz
