I've seen this said a few times, and I am confused by it. I must be missing something. If you have an electric plane and a battery, and you fly until it is empty... then you have to charge the battery. This takes several hours, right? With a glow plane, you would simply fill the fuel tank and go right back up. There seems too me to be a huge difference. Electric you make one flight and wait a few hours for the battery to re-charge... Glow you fill the tank and are back up in under 10 minutes if you want too be. What am I missing? Do people who use electric planes have 5 batteries for their plane, or something?
