Looks like the HG crowd is jumping on the electric bandwagon too.

That was nifty - seems like a good use for electrics. It looked like the pilot got the tow
rope, and the glider went for the ride. That surprised me.

The next video that played had me also surprised to see a drogue chute used for the landing!

Except the part about burning out both motors...

That's how hang-glider aerotow works...

These machines are high enough LD that landing without drag devices
can be a PITA. Some have deployable drag device on the extended keel.

I spent today trying to repair my electric machine, aaarrggg....
With a nice break when Nico visited for a socially distant lunch!
Failure #24 fixed, #23 still intermittent (I HATE intermittent problems)...
See ya, Dave

We were too late to make the big bucks as engineers explaining cats, but I see a window for a
second chance at fame: engineers explaining electric propulsion to HG pilots. "Plane Talk by
Dave and Eric" will never match Car Talk in audience numbers, but we could earn enough that you
could trade the Antares in for an AS34.

There are a number of self launchers. Quite a number of videos if you search.
Power mostly from modified large model motors. Some adapting electric tool batteries.
Power below needs for sailplanes. Max about 15kw.
