Speed 400s draw about 10 amps for good power. I want to use three 6 v. S400s. A singe motor seems to run fine with an 8.4 v. battery.

With 3 of these in series, the voltage needs to be about 24 volts, which would deliver 8 volts per motor.

Is the current draw on all three still 10 amps??

Please, someone, tell me if I have this right??

With a plane with AUW near 48 oz. work with a 20 x 1100 battery pack??

you are correct, you will need an esc that can handle that kind of voltage, and a UBEC or an onboard receiver battery. I've run twins in series (never a trimotor) and it worked great.
