Last IGC decided to make electric self-launch capability compulsory for
13.5m class,

So, who will be first to fit a FES to a PW-5?

Doesn't this make the World Class into a defunct, historic curiosity
since it has effectively been replaced by the 13.5m class?

Historical moment?

Definitely!

Thinking of PW-5 nose ground clearance, fitting FES would make a rather expensive lawnmower. But isn't there a UK company that is in the process of fitting not only jet but ELECTRIC engine driving wheels of glider that has PW-5 wings? And no, I believe IGC did not have this in mind when deciding on "electrical self launching" capability.

True enough - my excuse is that its years since I've seen one.

I remember seeing adverts and articles about that, again some time back
and nothing recently, so I can only assume that the project imploded.
IIRC the guy behind it was at one time the UK AC-4 agent: doesn't have a
lot of luck, does he?

Thinking about the AC-4M, I wonder if would it be possible to electrify
one by replacing its pop-up IC engine and fuel tank with a brushless
motor and battery. Even of possible, I suspect it would be left in the
dust behind the current 13.5m electric self-launchers, so a fun project
if ultimately futile.

Good to see its still progressing. Some dimensions and performance
estimates would be nice.

The company was wound up in a solvent liquidation, having failed to raise sufficient funds to complete the project. I believe the main director is attempting to resuscitate the project. It would have been the cheapest self launching glider by far, at the expense of considerably less good glide performance than the Silent or other newer 13.5 m gliders.
