A main difference between glow and electric is price and performance. You can get the same (or better) performance with electrics it simply costs more then glow at this time.

One thing you have to be carefull with is posts comparing park/slow flyers to standard (.40-60) size glow powered planes. The comparision is incorrect and misleading. Its like comparing the performance of a Ford Escort to a sports car.

Park flyers can be easier to fly because they are designed to fly slowly this gives the newbie more time to react.
They also seem to handle crashes with less damage due to their light weight and slow flying speeds.

Nothing beats one on one instruction but if you can't A park flyer like the slow stick or tigermoth may be the way to go.
