RE: small engine?
Well it would be a brick with a high wing loading but yours is below 9oz / sq ft. If you have a high lift airfoil you may have a neat little motorglider! I would expect long shallow climbs and maybe even some thermalling! The smaller canard wing may stall at lower speeds though! [X(]
For instance I have a Dynaflite Wanderer glider, and with a cox .049 power pod. It gives me some ridiculous power loading figure of well over 600! As a sport plane that would suck, but as a glider it is graceful with big spiraling climbs. Any more power is overkill for what the plane was built for. On the other hand I have a little pylon racer with a power loading of 153! But it would fall out of the sky with anything more than 300 because the wing loading is high for a small model (around 20oz/sq ft).
So just use the figure for comparison. The numbers given work for sport flying but must be adjusted when you are talking about gliders, racers, scale, etc.
