I once made a website dedicated to all the boxes UPS busted up for me in 3 months. (I took digital photos and sent them to Tower... then when the 5th reship of the same order came in smashed... I made the website) I left it up... (might still be there.. it would be on FortuneCity.com They hadn't deleted it when it had been up over 9 months with no edits.)

The Ercoupe is an interresting aircraft. The originals had no moveable rudder and no rudder pedals. They were marketed as a "crashproof" airplane. (

right... it flies it can crash

) They are nearly impossible to spin. (the CG is too far forward and the wings have significant wash-out)
Later models had the rudders made moveable with either rudder pedals or linkage to the ailerons. There were retrofit kits sold to make the rudders moveable on any one of them.
Color schemes are abundant for scale modeling. If you can think of it... there was probably one painted that way at some time. I had a neighbor that owned one painted in late 1930's army trainer style. (see PT-19 triners) A few were used as military trainers durring WWII, and some got used by the military as late as Vietnam.
Default was fabric covered wings and all metal fuselage. You could have the wing aluminum covered at a loss of appx 70 lbs maximum cargo weight (which meant you could only have two 200 lb people in it with no baggage if it had full fuel)
(hmm... someone might think I like the things.
