I’m working with pixhawk mini 3dr, and I’m having problems with connecting with the RC. It’s written it needs 5 channels, and it’s 0 channel. I need help with this

What RC transmitter model?
What RC receiver moder?
What Ardupilot Firmware version?

Did you read the documentation ?

• http://ardupilot.org/copter/docs/common-pixhawk-and-px4-compatible-rc-transmitter-and-receiver-systems.html
• http://ardupilot.org/copter/docs/common-radio-control-calibration.html#
• http://ardupilot.org/copter/docs/common-rcmap.html

ps. if you want help from this website you should install Ardupilot instead of PX4 firmware.
