Graupner's inexpensive Speed 400 motors are creating a brand of electric R/C flight of their own. These small 50-ish watt motors swing 5'' props in direct drive, or 8'' props when geared. These motors would make interesting multiengine designs on an inexpensive and simple scale. Four-motor geared Speed 400 designs would power 48-60'' wingspan planes weighing around 4 lbs ready to fly. Such planes might use 24-28 of the small 500 maH receiver-type nicads if wired in series (w/ speed control), or only 7 big sub-C or C-type cells if wired in parallel (using an on-off switch). Even fairly cheap ($30) 100-watt motors like the Master Airscrew geared systems can be effectively used in twin engine systems up to 4-5 lbs of weight, and 4-motor designs up to 8 lbs! With single motors up to ``90'' size (> 1500 watts), the sky's truly the limit!
How does that P-38 sound NOW? <grin>
