Hello Nigel

You can't be serious to suggest such an foolish motor to power an Europa. Even
though it may work, the craft would be hard to balance because it would be very
tail heavy, and the installation is not very conducive to keep the back end of
the plane from burning off.

Scheeeze.

Now if you would have suggested placing a small pulse jet at the tip of each
blade of a CS 4 bladed prop, making the smallest of simple very aerodynamic
cowlings (reverse funnel), with the prop way out in front which would give you
ample clearance for the 8 foot diameter, and a small but powerful Brushless 3
phase DC motor (60,000 rpm with planetary redrive) that would start the beast
and even allow it to sustain for a while or a longer while by adding more
batteries, and storing the LiIon batteries in the wings. It would  be run by
propane which is easy to feed, and have a heat exchanger that would convert the
liquid propane to gas and keep the pressure up. This heat exchanger would dump
some heat to the cockpit in the winter from the hot side,  and  remove some heat
in the summer form the cold side.The FWF could as quickly exchanged as the
glider wings can.

Then you would be onto something!

Please send a photo of the testing fire when the LiIons catch fire! Please send
a photo of Europa Glider thermaling above that fire when the BLEVE happens.
