What is involved regulation wise adding an electric motor to a glider?

I raced RD-250 in 250 Modified Production and TA-125 in GP classes during my mis-spent youth. Fun stuff, but there is no way I'd trust my life to the continued operation of a tightly-wound two-stroke motor. I didn't think I'd mess around with motorgliders at all until brushless motors and Lithium batteries came along. Now I think that electric motorgliders are poised to become the core of our sport, with pure sailplanes becoming more of a fringe activity.

if you're trusting your life to the operation of any motorglider engine,
you're screwing up bigtime. Electrics can and do fail, right along with
the others.
