My Ercoupe aircraft dimensional diagram shows it to be 75". -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of William R. Bayne Sent: Friday, February 26, 2010 3:12 PM To: ety Subject: Re: [ercoupe-tech] Tail Height
Ed said (excerpted from below): With the double fork nose gear, which is about 1.5" longer, the needed tail height would be 76.5". This is only partially true. With the original double-fork nose gear (fitted to serials thru 186) and the 4" Hayes nose wheel the tail should still be 75" high. With the Univair double-fork nose gear (see Parts Manual p. 21, Fig. 16), the 5" Cleveland nose wheel and taxi spring U415-34104 (shorter) the tail should still be approximately 75" high...again, level sill controls, as Ed stated.

With the original nose gear fork the tail should be 75" high. Back to the basics, the criteria is for the window sills to be level - that's what gives the correct wing angle of attack on the ground, dumping lift and allowing the correct crosswind takeoff and landing safety. You can find the detailed information on tail height and spacers written by Bill Coons on Skyport's website, way down at the bottom of the page: http://ercoupeparts.com Ed Burkhead
