When I teach someone to fly I do it with glow. Learning to fly takes flight time and if a newbie comes to the field with an electric plane and two batteries it's not much help. With my simple Tower trainer, I get at least a half dozen 20 minute flights and then top off the 2000Mah battery and go for more. The whole key with learning is getting flight time and if a beginner doesn't have enough batterries or a good charger you lose a big part of the day. I tell people that after they learn to fly they have a lot of choices, but IMO I'll always say glow.
