I just gotta ask, "Why"?
What is the cost of the conversion?* Is the engine failed and not repairable? Are there a lot
of brownie points for "saving the planet"?
If I wanted to, my gas powered Stemme could reach just about anywhere in the western states on
a single tank of gas.* The electric offerings from Stemme have great range at the expense of
carrying a gas-powered generator along to make the electric power to run the motor.* Where's
the advantage?

Don't take it personally :^) Kenn is converting an AC-5 Russia, a WAY DIFFERENT glider than the
Stemme! It has a rattlely, unreliable motor of modest power, but I'll let Kenn fill in the details
of his decision.

Also, Hank concluded with this piece of advice:
"To my knowledge this has been done once so far in the US .
If you want an electric sailplane- buy one."
Sounds prudent to me.
Some people like the challenge, much as glider pilots do in their flying (or they'd get an
airplane): Ken Sebesta, a participant here, has removed the self-launching gas motor from his
AC-5 Russia and is replacing it with an electric motor. I believe he's bench-tested the
motor, ESC, and batteries, and is now working out the motor mounting details.
