Hi Scott,
Go into the FUNC Menu, select Flap (FLP) then select control (CTR) and select J1. Now your "limits" will work for both aileron and flap.
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
