First I sold "all occasion cards" (many of them) to get a Wen Mac Bonanza, which clearly was a fail. Better, later we got a Cox P-40 (not the crappy little newer one, the original) which had a much better engine. After we finally destroyed it, we used its engine and parts from an engine scrap box ($10 total) from an El Paso hobby shop to get into Scientific balsa models, and our own copies of them, when we finally learned to fly CL. We then progressed to our "combat wing" models with an Omega, and multiple homemade copies of it. Never learned much beyond wingovers and inside loops from these, but had a lot of fun.
I also would rush many blocks to see any model airplane fly and a box fuselage Fox .35 powered Goldberg model was absolutely awesome. When I finally saw a big flapped stunter with .35 power, I couldn't believe how slow it flew and what it was capable of.
I don't think an electric model would have been as much as an inspiration for me, at least for building stunters.
Today, I see things differently, because modern electric power technology is simply awesome, and practically resolves a primary aspect of CL stunt - consistent, reliable power delivery.
To be realistic, you have to wonder how many potential CL stunt enthusiasts were lost to their crappy plastic .049 models experience.
