what is the correct procedure to program tx to esc...
tx on..throttle stick at full power with throttle trim at full throttle also...
connect battery and wait for beeps to stop.....
then lower throttle stick to full down also throtte trim to full down...
disconnect battery and tx to off...
does this sound correct to you experienced ?thanks....Richard

You dont need to mess with the trim. Also, not all ESC's are created equal, find the manual for your particular ESC.

But usually,....

Full throttle > plug in battery > wait for beeps > low throttle then the ESC should count the cells and arm.

Thank You Sir
