So you're spending 150k Euro on your glider then trying to save a few Euro

The climb rate of a FES glider easily beats the traditional Turbos but do
you really want to use up the limited duration of the batteries in this
phase of the flight?

You'd be better off taking the higher tow & saving the FES for the retrieve
if needed.
Or take the lower tow & soar

Hi everybody.
I would like to know the opinion of a owner of a HPH Shark with FES.
Which is the true climb rate?.
Somebody has proven to use FES like a supplement tow mechanism?. I mean,
how efficient is take a tow to 300 or 400 m and later start FES to climb
at
900 or 1000 m.

Thank you very much.

Juan.

You'll get at least 2m/s dry. But like PF says, better to take a tow to 400m and use the FES straight and level until you find a thermal. It's much more efficient in level flight than climbing.
