Never was a fan of the rudder pedal mod. The rudders aren't terribly effective anyway
being that only one deflects at a time and they're small. Adding pedals serves only to ruin
the fun of crabbing it right down on the ground.
Which is not the way most of us were trained
but incredibly entertaining and perfectly safe.
To be honest, I don't know how many of these 'advisers' had actually flown an Ercoupe, and how many were just offering their opinion. My biggest concern was always, how well do they do in a vicious Oklahoma cross wind? I remember one time specifically when I was still working on my Private ticket and I had to deal with the worst wind shear I have ever experienced, and I was solo. My instructor happened to be flying with another student and he was in the pattern watching/coaching me. It worked out well, but there was certainly some pucker factor!
