Freddy,

What do you mean?

I'll tellya this about this past weekend at the Jackson NJ contest. There were several guys that had DaveL's electric set-up in their planes. Neu geared motor turning very quiet 21X14 carbon props. The main noise maker was the gear box in the air

To me, it was quite curious that the noise in the air of the Neu powered models was not much different than the 2 stroked, piped models. The other interesting tidbit was that there was virtually no difference in the sound of the glow engines and the gasoline engine I was flying (2 strokes only of course)
