Not much can compare to the sound of 4 propellers turning in synchronization! This example is modeled around the Royal B-17 kit, which spans 78'' in wingspan. Designed to house four .20 glow engines, this design can make an excellent-flying 4-motor electric when lightened appropriately. In particular, most multiengine glow kits have ``overbuilt'' fuselages and engine nacelles due to engine vibration and overpowering. Since electrics have no vibration, nacelle and fuselage weight can be reduced substantially. Actual flying weight as an electric, using 4 geared Astro 05's (or equivalent) on 24-32 cells, is about 9-11 lbs. With typically 150-200 watts per motor (600-800 watts total), we see that we have 60-80 watts/lb, right where we need to be for exciting flight performance. A single speed control can handle all four motors when wired in series.
