Well, that answers the question of how to fit the FES to a glider with a non-circular nose section, like the Discus and Ventus!

I wonder who the intended buyer is, though. Avid racers won't like the extra drag and those attracted to self-launchers won't have enough power. Are there enough folks like me who fly a fair amount of cross-country and who like the idea of a reliable sustainer?

This is a big prop. I wonder if they tried to self launch it. I bet the engine is powerful enough and it is all about battery capacity.

I wonder if they are using the CG tow hook, or if they have installed a
hook forward of that. I thought that you couldn't have a new glider
with only a CG hook in Europe.

There is a suitable space for a front hook below instrument panel, where is usualy located front battery. This battery is not required anymore.

You are right, we made a bigger chord of the blade, in order to load motor more. We expect about 26kW of max power, which will be enough even for selflaunch. Battery compartment is designed in a way so that there will be a possibility to install bigger battery pack, which will allow range of 180km of level flight or altitude gain of 2000m!

I would be interested to know if it can be fitted into an ASW27.

I suspect that there's not enough ground clearance to self-launch, but a vehicle launch to modest height plus a climb out on the electric motor might work (some weaker self-launchers use this technique, especially at high density altitudes).

No doubt the developers will let us know!

There is enough ground clearence for a selflaunch from concrete runway or smooth grass.

From a competition pilot point of view there would have to be a small drag penalty and a weight penalty. But both of those would seem to be pretty small in comparison to the competitive benefit that arises from the ability to stick to the course line and never have to be distracted by the need to deviate towards a landing option. I don't have experience to know, but I'm suspecting that the reliability of the FES might be sufficient that one could drive it straight into the boonies then flip the switch only at the last minute -- wouldn't that be exciting? You certainly can't do that with a gas engine.
