Fandain,
The very last thing you want to do is run into someone with a glow powered airplane. Someone can get very seriously hurt. People riding bikes, or cars coming down a road is NOT the place to fly glow powered airplanes. I can't stress it enough, you need to join a club or at least find a flat place where there any traffic, bicycle, automobile, or otherwise. Do a search and find out where there is a club near you.
