Default FES underpowered for 18m ship?

It's a different mindset. With your self launcher, and my conventional
turbo, if you start the engine you drive home.

With my FES if I need to climb I only climb as little as possible, then I'm
back in the "Soaring" game to get as close to home as I can. I just have
the option of setting my glide angle to something more favourable. And in
the UK will almost certainly have the option of an Airfield on the way home
if I need it

If the engine dies then I'm still in the same situation all of us are in,
so I don't fly over unlandable terrain with or without the FES running
(I'll make an exception for the Solent)

Flying in the UK 1200ft normally gives a pretty wide choice of fields

Are you saying that you would cruise home level at 1,200 foot above the
