Mode­lair­plane­ Mul­ti­mo­tor Se­tups

Electric Flight - - AIRMAIL -

We just posted an ar­ti­cle on the finer points of set­ting up model air­planes with mul­ti­ple mo­tors. When it comes to twin- or quad-power se­tups, electrics are far more re­li­able than the equiv­a­lent setup us­ing a “wet” en­gine. We dis­cussed sev­eral ways you can go about it, and here are some of your com­ments.

Marc De­laney: Great ar­ti­cle. I have a P-38 in which I put two Scor­pion SII-3014-1220 V2 brush­less mo­tors with two Cas­tle Cre­ations 50A speed con­trols. I use two 3S 2200mah 25C Lipo packs, wires in par­al­lel.

Ge­orge Watkins: This is just what I was look­ing for. I am think­ing of buy­ing a B-17 bomber from a friend and re­plac­ing the old glow en­gines with brush­less mo­tors. Thanks for the in­for­ma­tion.

Peter Shank: Nice, clear, straight­for­ward ar­ti­cle. If I were to con­vert my Ziroli B-25, I think I would also hook the throt­tles up to the rud­der chan­nel so that I could have dif­fer­en­tial con­trol for bet­ter taxi­ing.

Karl Laskie: Thank good­ness for Lipo bat­ter­ies. I used to have an elec­tric-pow­ered B-26 “Widow Maker,” which I pow­ered with Sub-c Ni-cds. It had a high wing load­ing, and I sold it. With Li­pos, I am sure it would have been more fun to fly.
