Gas power plane convert to Slope Glider?

in strong wind condition, even a star destroyer can fly ~ ~

actualy, i done so many "power into glider conversion" before.
you dont believe it,
the most performence one is a mig 15 ....

but always remember,
the stronger wind you get,
the easier to fly such a big scale...

...and more difficult to land it due to high speed in such swift condition.
