Yeah, RC Planes, my little new X-Freak (Aerobatic unscale plane), with 1.5m (around 5 feet i think) wingspan and the T-46 2cycle engine is not as bad. I like flying it high, turn it upside down, and let it fall from the sky with full throttle, than pull up, so that you end 2 feet above ground and fly across myself with some 70-80 knots 3 feet away from my face.
