Default RE: the rational of trimming

Thanks guys -
on slot car motors permenant magnet stuff - the car braking is accomplished by simply shorting across the the tracks VERY effective .
As I noted I really oversimplified the braking info - Just trying to note that braking is possible in the setups we fly .
I use a number of outrunners and sme of the speed controllers offer a variety of power setups
On older cars the generators -if the belt was removed -somtimes acted as electric motors -as anyone wih experience in these things knows, this type motor and generator are basically the same bits n pieces
I do fly both small and very powerful electric planes and the results are as I noted
The power consumption and shaft output are not as shown in the "chart"

Actually the power efficiency in the really good electric motors for pattern airplanes -is close to -90 %!!
And If you use really GOOD batteries capable of momentary excursions to better than 50C output- the torque available at speed, is astounding


Sadly , in some locals- there is now a very divided camp between IC and electric-for aerobatic stuff.
