Like as has been said by others, I don't see that many electrics at the flying field but I consider that deceiving because many electrics are flown in one's back yard, the school playground, or the factory parking lot.

The guy I fly with always has his big glow and gas models at the flying field and we will stay out there all day but he lives in a rural area with a large treeless yard and flies his electrics at home. He has four nice 3D ones. He'll get out behind his barn at the end of the day when the wind dies down and fly two or three flights before it gets too dark. He has both built up ones and Depron foam ones. They are brushless with lipo batteries
