An aileron bellcrank that is at an other-than-90-degree angle effects this behavior, is standard even in radio-controlled models, and shouldn't be anything unusual. Indeed, most modern aircraft have differential aileron behavior in an effort to prevent stall-spin traps. It's just safer to push a wing DOWN than to try and lift the other one UP! There has rarely been another more perfect example of aerodynamic balance than the Ercoupe. From the cant of its engine mounts to the P-factor cheat of its H-tail, it's a delicate balance. Then again, that's why it feels so damned good. In GA only the Beech Bonanza rivals it...and the Bonanza exceeds us in the sense that a V-tail from 1950 feels right whether it has the original 225HP or a thumping 300HP. My experience suggests that even at 100HP, the Ercoupe balance starts to go off-kilter in climbs. Bonanzas don't. Wow.
