To add to this if you have an Airtronics, or JR, or something other than a futaba you have to make sure the throttle servo is set to normal. If it is set to reverse all of the programming will work properly but you will get no throttle control.
Turn your mamba off and make sure you have the throttle servo setting correct. Then reprogram the mamba.
