I'm having trouble setting up matching servo travel for flaps and as this is my first Spektrum radio cannot for the life of me see where I'm going wrong.

Wing type: 2 Ailerons: 2 Flaps.

This is the set up for the flaps:-
Channel Input Configuration:-
Channel 8 - Aux 3 - Switch E (3 position)
Channel 9 - Aux 4 - N/A

RX Port Assignment:-
Channel 8 - Aux 3 - Right Flap.
Channel 9 - Aux 4 - Left Flap.

Tried setting the travels on each servo and cannot get them to move the same amount. Is this something to do with Channel 9 Input Configuration being N/A?

Thanks

The size of the increments of travel and trim can be set on most channels

Go through as you found, there is a discrepancy on the channels you are using

Are you using switch E to move the flaps? If so you need to assign Switch E to channel 9 as well, so switch E is switching both channels, and hence both servos.

Hi Denis. Thanks for that but can you give me any guidance on the location of this facility? I can't see any options that do this in the Model Setup screens.

Hi Don. Yes, I've set Ch. 8 to SW E but am unable to select the same option in Ch. 9. However, SW E is operating both servos, it's just that the one in Ch. 9 does not replicate the same movement as the servo in Ch. 8. Channels 1 - 7 and 9 have all been automatically set to 'N/A' by the transmitter. I assume that this has been pre-defined when I set the wing type to '2 Ailerons - 2 Flaps'.

Most likely unrelated, but I was playing around with my lowly DX8g1 and mixes when I had the same sort of issue. I had reduced the travel on one of the aux channels which produced the effect where the channels would not follow each other.

Hope that helps

Woops, I jumped in as my DX6 a Trim Setup

Trim Setup,

Model Utilities.

Use The Trim Setup Screen To Change The Size Of The Trim Step And The Trim Type.

I just assumed that the mighty 12, would have the same facilty

On my Dx9 I don't have any switch allocated in the Channel Input Config menu.

It's allocated in Function List-Flap System-Switch. You use the same menu (Flap System) to adjust the Throw & Elevator Compensation mixing. Hope that helps, afraid I've not used an iX12.
