Radio System FAQ

How can I set up a twin that uses rudder-to-throttle mixing to have throttle aid water steering and slow speed steering? The rudder-to-throttle mixing should not function when above 1/2 throttle. I also want to have one engine only options on throttle.
"I am using an 8-ch receiver."
Servo Set-up:channel 7 = left throttlechannel 8 = right throttle
Mix throttle to channel 7 100% and throttle 3 to channel 8 100%. This will operate the throttles from the throttle stick. Nothing is plugged into channel 3.Goto PMIX1, make it active, channel 3 primary, channel 7secondary, +100% on full throttle, +100 on idle, trim on, link off, no offset, active switch C up/ctr

Goto PMIX2, make it active, channel 3 primary, channel 8 secondary, +100% on full throttle, +100 on idle, trim on, linkoff, no offset, active switch C ctr/dwn

Mix rudder to channel 7 on right rudder application only, causing channel 7 to increase proportional to the rudder input. Active only with throttle stick below 1/2.

Do the same for left rudder with channel 8. Active only with throttle stick below 1/2.

Go to PMIX3, make it active, rudder primary, channel 7 secondary, while holding right rudder input turn dial to right until get the amount of desired engine throttle up. Leave the left input at 0. Link off, trim on, offset 0, command is STK-THR. Move throttle to 1/2 stick position and set the % by holding down the Dial for 1 second. Turn the dial left to make it -, this means active below 1/2 stick.

Go to PMIX4, make it active, rudder primary, channel 8 secondary, hold left rudder and set the %, leave right input 0. Link off, trim on, offset 0, STK-THR, set % and change sign to -.

NOTE: the exclusive AUX-CH screen of the 9C allows you to turn off the aux1 and aux2 control knobs quickly and easily without having to use up a PMIX. Simply go to the basic menu, to Aux-CH, select channel 7, turn dial until reads NULL, arrow down to channel 8 and do the same.
"I am using a 7-ch receiver."
Servo Set-up:channel 3 = left throttlechannel 7 = right throttle
Mix throttle to channel 7 100%. This will operate both throttles from the throttle stick. Goto PMIX1, make it active, channel 3 primary, channel 7secondary, +100% on full throttle, +100 on idle, trim on, link off, no offset, active switch C ctr/dwn.
Mix throttle to throttle -100% to keep channel 3 servo from responding when switch is C down. Goto PMIX2, master throttle, slave throttle, link off, trim off, Switch C Down
Offset mix channel 7 on right rudder application only, causing channel 7 to increase proportional to the rudder input. Active only with throttle stick below 1/2.

Do the same for left rudder with channel 3. Active only with throttle stick below 1/2.

Go to PMIX3, make it active, rudder primary, channel 7 secondary, while holding right rudder input turn dial to right until get the amount of desired engine throttle up. Leave the left input at 0.
