No reserse. What do I need to do?

Q. Hey I just got the hobby wing max 6 to go with my new EXB Kraton. And I programmed my receiver to the ESC but I’m not getting any reverse. It runs great is fast. And stops. but no reverse. .

The main thing with no Reverse is the radio actually.
The Max series, will default with reverse Turned on, so if the reverse is not working, but forward does typically means a few simple checks will find the issue.

3 basic topics.
The ESC has either been changed to Forward/Brake mode.
The calibration has not been done,
The radio, does not have any reverse output, or non standard reverse output. 

The following is a rundown on how to check for these topics. 

This test is assuming that you turn on the vehicle now and can operate the Steering, and the Servo responds correctly. 
How to confirm the receiver Throttle Channel outputs:

- Plug a servo into the Throttle Channel.
- Plug the ESC into the "Battery Slot" or the "Bind Slot" on the RX.

Turn it on, and move the Throttle on the radio.
- If the servo does not move, you have discovered the problem.

The 'Servo test' in the throttle, lets you "see" how far the servo moves when you move the Throttle and Reverse.
- The idea is that it should move the same amount both directions. Often, it does not. This can make the ESC get stuck or not calibrate. The radios settings need to be reviewed so that the Brake/Reverse side is the same as the throttle.

In many problem situations, the throttle does not work at all, or the neutral is way off, or the brake side does not operate correctly. This test helps confirm that your throttle/neutral/Brake/Rev on your radio system is working or not working. If it is not working, the ESC will also not work. Some radios have "ABS" or pulse the reverse/brakes, this also makes reverse not work.
