It seems like the car guys rc and full scale will always help fuel availability. My problem will be lack of spares. If I bend a crankshaft on my Super Tigre 2300 I'll be hunting through ebay for a replacement. All of the low end glow engine companies are just gone except OS. I love the smell and experience of flying glow but maybe not enough to pay for YS, Saito, Rossi, and the like. Even OS is pretty pricey for what you get. For glow to make a big comeback we need some good value choices in my opinion......
