Pickygit Posted September 4, 2018 Share Posted September 4, 2018 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 Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted September 4, 2018 Share Posted September 4, 2018 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 Quote Link to comment Share on other sites More sharing options...
Don Fry Posted September 4, 2018 Share Posted September 4, 2018 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. Quote Link to comment Share on other sites More sharing options...

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.

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'.

Chris Walby Posted September 4, 2018 Share Posted September 4, 2018 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 Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted September 4, 2018 Share Posted September 4, 2018 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 Quote Link to comment Share on other sites More sharing options...
John Lee Posted September 4, 2018 Share Posted September 4, 2018 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.
