Wow, so only 5 min flights can be expected? LOL, that's just enough to start having fun. Also, crashing and burning up both a field and heli wouldn't be too cool. I can just see images of the heli going down out of site. In the meantime I'm looking for it and see smoke, oh there it is!
Imagine someone out west causing a wild fire by an rc heli.
I'm sure they don't burst into flames every crash, but if they can get a good flame going that's a bit scary.
