But if you are 100km away from your airfield, especially if you

used your battery for take off, there will be little or no use of

FES.

I like the idea, but sorry, with current Li-ion batteries with max

150Wh/kg, this is not very promising technology. I am waiting for

Li-S, or Li-Air cells, then we can talk seriously about FES.

As mentined above already at Ventus we have enough margin of max weight of non lifting parts, so that we were able to integrate bigger battery compartment box, so that we can fit inside bigger battery packs (50kg instead of standard 32kg). Range of 180km of level flight or 2000m altitude gain is more than sufficient!
