Some years ago a couple fellows I know were making some forward ‘V’ swept wing planes they called a Vortex. I built a few and flew them. They were made of built up balsa and used .25 FX glow engines. They were capable of some pretty impressive speed and maneuvers.
But today, I avoid glow fuel planes. I have started using electric motors and am still learning how to apply them. The Mini Electric Vortex is the latest plane I have been building. It is only similar to the original Vortex in appearance. Construction, size and shape is different along with electric power instead of glow fuel.
