RE: Needed: a picture of a Piper Cub Dummy Engine
rinoldi,
The Enya .29 is a great size for this plane. If you haven't flown one before, you'll love how well it flies (an floats) - just like the real thing. Take your time when you drill the blocks for the dowels that hold the tail on - it's really easy to drill them at an angle and have the stab halves mis-align, and it requires the wing struts unless you want to play helicoptor pilot in mid flight.
Lets see a build thread so those who have not had the pleasure of taking a pile of sticks and making a Cub see what real building used to be like.
