It seems to me that there are two distinct camps of R/C er's out there. The Glow-Heads and Watt-age boys. I am tempted to go electric simply because of the time lost loading and de-planing and the travel time to the field Vs. running over to many of the open fields nearby to fly. But the thought of flying a FOAMY type plane and learning about volts, amps and lithium-ion-plutonium batteries bores me to sleep. SO, Why doesn't some smart guy invent a quiet glow engine that could be use to power 7lb planes, in a mild breeze rather than a nutron-ium battery!!. There must be a HUGE market out there for this type of park flyer. Just look at all the new AMA members just on the other side of that hill flying around the baseball diamond thinking about that GIANT scale warbird, someday. Well, for my 2cents I 'd tell the engine mfg. guys stop building bigger glow 4cyl stuff and think about the future. Smaller is where it's going and sshhhhhh quieter too!/
