I need help on a orion esc can't get it set up to my receiver it's a vortex r10 looks to be a couple of years old

Check that you don't have to reverse the throttle on your. Radio.

Just the steering works that's all no thottle response

Did you calibrate the ESC?

No I have tried can't get it to calibrate

Its pretty simple. Do you have the manual?

Press the button on the ESC then turn on your transmitter. Once you turn on the transmitter you will see red lights start to flash. Let go as soon as this happens for calibrating.

If you want to make adjustments then hold the button for one second after everything has been turned on as the manual indicates
