Overall, the FES sounds like a very good option to me.
However someone mentioned the real possibility of prop strike. If this happen, I still want to be able to fly my glider as a pure glider until I get the new prop, but if I need to send the motor for repair, or worse, send my ship to Europe to repair the motor, then this could be a deal breaker. Anyone knows more about the consequences (and cost) of prop strike?
According to the FES site, an FES glider can be easily returned to the "pure
glider" configuration. The motor and propeller are removed and a nose cone is
attached; the batteries can be removed the usual way. I suspect the weight and
balance would still be correct, too.

I have no idea what the cost of the prop strike would be, but I recall reading
about one, and the motor was undamaged. The motor is simple and easily examined,
unlike a gasoline motor.
