Idle Current?? Long duration glider flight.
I need a brushless to put in a Cularis that I use for long duration FPV flying. The motor that came with the plane is a HiMax outrunner and it seems rather underpowered. So I want to step it up a notch. But since I am using this for long duration flights with the motor "off" most of the time, I am concerned about current draw. Most specs refer to an "Idle Current" circa 1 amp. This is way too much, considering I also have a Video TX, 6 servos etc etc. Do these motors really draw this much current with the throttle off, and if so, how does one get around this? Any recommended motors out there

RE: Idle Current?? Long duration glider flight.
I've not seen one that draws a whole amp, but yes some do draw some power when the throttle is off. I believe this to be an error in the firmware in some ESC's, the ESC should allow the prop to spin freely and draw no power when the throttle is off. A folding prop that stops completely should fix it.
