I recall that Luscombe versus Ercoupe article, but I think they were more comparing flight characteristics than dogfighting.
Yep, there's a huge advantage to flying an airplane that will take care of you, no matter how tight you turn. With an Ercoupe you can stall it and just keep the wheel back. The airplane will recover on its own, stall again, recover again, and keep doing that until you either start flying it again or you hit the ground. Not only that, but while in the stall you can roll it into a steep bank and it's still keep doing the same thing, at a higher airspeed and faster rate of descent.
There was one guy who insisted he could make an Ercoupe spin. He managed to jam the controls and not spin but spiral at a steep angle into the ground. That produced a recommended mod to the nosewheel steering connection, which is what jammed.
I read that one guy got the rudder-aileron mixer control connections wrong so it was giving opposite rudder. He flew around for a while with it hooked up that way, until one day his Ercoupe was parked next to another one and an A&P walked by, did a double take, and said, "Something is wrong! The nosewheels are pointed the same way on these two airplanes but the rudders are opposite!"' I had a very high experienced aircrfat restoration expert (Silver Hill) tell me it was impossible to hook up the rudders backward, but over 20 years later I took the mixer control out to referb it and managed to do that very thing - TWICE. I noted it because the control cables were rubbing and I started looking at why.
