First ??? all electric plane down in Hungary

In flight fire reported

So what actually happened ?

The actual airplane was all electric. No hybrid.

The accident plane is all over that publication… See pages 24-25.

For those interested in electric propulsion I suppose this publication gives a complete overview of what’s going on btw.

Indeed Maoraigh, no sense speculating that the power plant is to blame.

Three of these have been built, HA-XEI and HA-XEF being fully electric and the third one (HA-XE..) is the hybrid one. XEF crashed.

Would the accident be unconnected to the engine type?

Maybe, maybe not. The airplane is a test bed for different propulsion systems. It could be this one:

Anyone know for sure which propulsion system the aircraft actually had?

the ‘soft pouch’ type of lithium cells as used in model aircraft, or the sealed can types used in cars

Only Tesla is using cylindrical cells. Every other car maker uses pouch cells, either as individual pouches or grouping a couple inside a roughly prismatic, usually aluminium, can. A number of these together will build a module, and a number of modules will build a pack.
Physical crash-worthiness is most often at the pack level. Given enough violence anything will give, once the shell is broken the cells are vulnerable, regardless of format.

I think that airplane is a hybrid actually. Diesel + electric.
