Hi from the UK. It’s due to blow over soon.
Tiny Trainer is an excellent first FT build, the speedbuild kit is not easy to find in the UK right now but the FT foamboard is sold in a few model shops and plans are free. I would look for a kit for your first plane build, it’s quicker and easier. Sussex Model Centre, Model Shop Leeds, Gliders UK, Steve Webb Models and a few other online stores have FT stuff. You can get alternatives to the FT power packs as well, both from Hobbyking and Model Shop Leeds, for much less £ than the Graupner ones.
Don’t buy heavy UK foamboard if you are building FT designs without modifications, it’s much heavier and alters the centre of gravity as well as the flight characteristics.
Planes are a little different from quads but much of the muscle memory you have from those will be useful. Just remember the throttle doesn’t make the plane go straight up!
