The website says the Swift will have a built in BRS - not sure how that affects how good or bad the spinning characteristics are allowed to be.
Here's another article on the Swift:

I did some work on car chassis using allowables for a flax pre-preg composite. It is not a structural material, but can be used for non-structural purposes. If used right it'll be a nice to have, but they won't be using bio resins for the high Tg cure cycles they want so that they can paint them black, which might reduce the overall green-ness of the design.
I like what they're doing and the way they're going about it. I wish I had their kit for what I want to do but the Swift design leaves something to be desired for me. Each to their own of course. I'll take this over Aeralis any day, but it must be recognised just how difficult it is to develop and certify aircraft in today's UK world.
