Hadn't crossed my mind. I've seen several glow flyers inquiring about electrics just to try something different. You don't mention how old your son is, or if he has any experience. Assuming that he's totally new to the sport, I am now shouting "Slow Stick" repeatedly at the top of my lungs. These things are perhaps the best electric trainer ever invented. They're inexpensive, nearly indestructable, easy to build and repair, use standard radio gear, are easy to fly, and can be modified to become a four channel aileron plane if you get tired of it. Best of all, they're a blast to fly and you can take 'em indoors when the weather doesn't cooperate. Just my $.02.
