So, we did get to see a C-150 today that is undergoing a beautiful restoration - and tried it on for size. When my wife and I both climbed in it was smaller than I remember a C-150 being and she said, "This is a tighter fit than the Ercoupe cockpit." The Ercoupe cockpit is actually nearly an inch wider and there is more hip room and shoulder room (especially in warm weather with the canopy open. So, we'll be keeping the 'Coupe and I'll have the wing in the right place. I did a pro-con list. The 'Coupe flies a bit slower but uses a gallon per hour less, it has wonderful visibility, can handle more crosswind component than the C-150, it is a great photography platform and, of course, the wing is in the right place. Also, it's all mine, no loan.
