It’s out of stock. FT have a new foam in development with Adams, it may be that they are waiting for that to come online. In the UK we are stuck with no FT board, not many speedbuild kits and a currency that’s diving faster than my worst flying disaster. Nobody here is restocking either.
I blame Graupner, they are meant to sort the stock out. No idea what the easy solution is.
You can substitute 3mm thick EU foamboard for the FT stuff and still get similar weight craft or you mod the FT designs by adding length to the nose to balance the heavier tails and by putting in bigger motors and batteries.
