Congratulations!
If you have been looking for a way to put the
FUN back into
your Sunday flying, you have just found it. The FUN 51 is a
nimble little
profile hot-dogger that assembles in only a few
hours and is easy on the budget. It does not require any special
building or flying skill - just a few hand tools and a little tail-
dragger time. With its oversized control surfaces it turns, loops
and rolls in the blink of an eye. But the thick, high lift airfoil and
light wing loading allow the plane to slow
way down for gentle
spot landings. If equipped with an engine like the Tower .40 it’s
possible to be airborne in a matter of feet, zip through three
rolls, loop on its own axis, and then go into the “hover” mode
while waiting for your buddies to get off the ground. What more
can we say? The Fun 51 maximizes fun for minimal cost and time!
