Wen-Mac
My parents bought me a Wen-Mac Corsair when I was a kid. Like someone else stated, I too learned to fly control line by swinging the model on really short lines without the engine running.
Later, my parents bought me the Wen-Mac P-38 Lightning. I was king of the neighborhood with that one. It came equipped with the vastly improved Mk.IV engines that I had absolutely no problem starting. My Wen-Macs used a discrete short glow plug. In those days, the Testors glow plug was readily available at the local hobbyshop, as was Testor's "39 Glow" fuel. That is what almost all of us used in Salem County, NJ.
