Setting Up Flight Mode Trim in the Spektrum iX14

[@txkflier]

See the description for how I use them..

Great quick tutorial. I use flight modes for independent trims similarly on my Radiomaster TX16S and Zorro. Interesting to see how it is setup on different radio systems. The iX radios certainly do have a clean, intuitive interface. Question, at about the 3:50 timestamp in the trim setup menu there are drop down boxes next to each channel and they are all 5. Curious what that number represents?

Trim Step: Adjusting the trim step value determines how many “clicks” of trim you input each time you press the trim button. Changing the trim step value to 0 disables the trim for the channel. To change the trim step value: 1. Select the trim channel you wish to change. 2. Select the trim step value and select the click value desired. The default value is 5.

@@txkflier Ah, ok it's trim step value. On my Radiomasters the options are Exponential (steps grow if you hold the trim switch), Extra Fine (1µS), Fine (2µS), Medium (4µS), and coarse (8µS).

Can you do a video showing how to use and when to use the top trimmer switches.

[@txkflier]

You can use those switches for a number of things. In my 80mm L-39 EDF with a Spektrum AR636 receiver, I use the left trim for an extra elevator trim that's only enabled when the plane is in SAFE mode. I set up a LT>ELE mix with a rate of 10% that's only on when switch B is in position 2. I'm going to replace the AR636 with an AR637T so that I can have flight pack voltage telemetry. It'll also let me adjust the pitch attitude trim for level flight in SAFE mode without having to hook it up to my laptop. Then I won't need the LT>ELE mix.

Thanks Txk..question ...when you set up your trims with the flaps this way, do the trims set for your flaps trim immediately . Is there a way to transfer those trim adjustments to the Flap system elevators so they match the gradual change on your flaps? Thanks

[@txkflier]

Yes, the trims change immediately, but that’s not a problem. I don’t trim my planes to fly level with the flaps down; I trim them to glide just above the stall speed like you would a full-scale airplane. If your plane balloons when you lower the flaps, you need to slow down more. Once I’ve set the trims for the proper glide speed/descent rate, I look at the position of the elevator in the monitor screen, note the value, center the trim, and then adjust the elevator mix in the flap system for the same value. However, you need to adjust the elevator linkage so that the trim is centered with the flaps up before you do any trimming for the flaps.

Can I also have safe and As3x as a flight modes on a different switch?

[@txkflier]

Yes, all you need to do is assign a switch to the channel you want to use to control the receiver's flight modes. The transmitter's flight modes have nothing to do with the receiver's flight modes. They can be used together, but it's better to use the transmitter's flight modes for the flaps or dual rates, if the plane doesn't have flaps. I have other videos about AS3X and SAFE.

How do you do this on the NX 8

[@txkflier]

It's basically the same menu names, but looks different.
