What port do you put power in?

Esc plugged into port 2 and power came from esc. Servo into port 1

will RC control work to control a mobility chair if wired the receiver into the chair control?

You are only limited by your knowledge and skill level. Yes, I could wire an electric chair/scooter to function with RC controls

When i try to bond receiver and transmitter all i get is beeps. i plugged the esc channel 2 but still beeps. am using a drone motor. that the problem?

The receiver is beeping ? Or the esc ? Don’t know about the receiver beeping but depending on the model of the esc, that could beep, channel 1 to turn and 2 to burn try plugging the esc in channel 2 and reverse the polarity. If still beeping consult your esc manual for endpoint adjustment and make sure the dumbo radio th and st adjustments are at zero
