...the range on a R/C airplane? I want to know how do the flaps work / move.
R/C elctric airplanes work with battery power..for both power and control. To drastically increase the range of an R/C airplane you would need to increase the power output of the transmitter...which violates FCC rules. You would then require a radio operatos's licence. This is not a good idea since you need to SEE the airplane in order to control it. Most small R/C planes are difficult to see even a few hundred feet away...well wihin the range of the control that is "normal" for it. If by flaps you mean the movasble surfaces inboard of the wings, they work by being activated by a servo which lowers them to slow the airplane down and increase the lift of the wing. They are generally used on landing only, although more protypically correct planes also use them on take-off.
