Estes E and F motors in the UK

[CrownUK]

Hi
I’m in the UK where Estes A-D engines have been easily available for years .
I can’t find out why E and F Estes motors are not available in the UK.
Does anyone have any idea ?

We also have the excellent Klima BP A-D 18mm engine’s produced in Germany and the TSP D E and F produced in Poland .

I would the E and F Estes ?

Likely not much help, but a recent discussion.
