Procedure for setting up flaps on the 4-Site
Ok, I think we got it nailed down now. Please make sure the plane works properly before doing any changes. You can always toggle the aileron mode to single channel ailerons and start over if it does not work for you. I reset my 4-Site back to stock mode and did the following steps to mod it for Flaps with elevator mixing.
Note: I did not unplug any servos or make any mods or changes to the connectors. Do not unplug any servo channels or change anything on the brick.
No changes are required for this mod. You can easily switch back to default by turning mixes off on the TX and toggle the aileron mode with stick programming to restore the default setup. This aileron mod will in no way change the planes original configuration as far as the connectors go. Its all done with programming.
Optional: It may be a good idea to remove the motor connector when doing the "stick" programming.
