Mike,
I understand.
My glider would be hard pressed to catch anything on fire, since it carries not fuel, but if I have the video gear in it, that means a Li-Po is in it too and that could burst. The other batteries are NiMh I'm not too worried about them catching fire.
As far as the 400' rule, that really seems to be in effect around real airports, like VNY, which the Apollo filed is very close to. I have yet to see an actual rule created by the FAA or AMA that dictates that I need to stay at or below 400' if I am 5 miles+ from the nearest airport. Since I fly at Pierce, I am out of that circle. As far as distance, our club was really into setting records, but everything was done in the desert, away from the general population.
The 400' rule is also why you don't see me at the basin. It's just no fun at the altitude.
When I am not flying FPV, I enjoy trying to set altitude records (unofficial).
As far as using RC planes as guided missiles, naw.... I can't see that happening.
The A, B and C are waypoints, so yes, i could program in a buildings coordinates and it would be easy to remotely fly to it and...
I have so much info available to me with my telemetry, it's just too easy to do.
