Hi Mike,
You will need to go into the Adjuster menu on your 3PK, this will be in Menu 3. From here you just need to select Throttle, when you get into the menu, you will see an arrow flashing by the word "Neutral", with a set percentage in parenthesis. At this point, just move your throttle to the desired new Neutral point and press the two set keys at the same time.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
Krysta
Lead Futaba Customer Service and Programming Technician
