Which sustainer system would you chose for your sailplane?

Approximate prices as of spring 2015...

D2c 18m - 68k Euro
D2cT 18m - 85k Euro
D2c FES 18m - 93k Euro

All plus VAT.
All plus loads of "Options"

By the time you've added a trailer & sensible instrument fit you're looking
at around 150k Euro inc VAT, so difference between "traditional" turbo &
FES is less than the variation in exchange rates from week to week (Or day
to day at the moment!)

I haven't compared that price to the price difference on a new glider
with and without a FES but I would guess that it was in line with buying
a new glider. Travel, shipping, and lodging costs are considerable for
the duration of the installation.

When is a hybrid coming? FES plus a 10hp generator would be the ideal combination.

Solar cells.

It shouldn't be long before it's economic to embed solar cells under a thin smooth transparent layer (would gelcoat do?) of the entire upper surface of the wing.

At current efficiencies, a single seater with 10 sq m of wing will get about 2 hp, not 10, but that will still help as it'll be working almost all the time.
