Something came up in the Mirage 2000 thread yesterday which has relevance beyond that particular model.
If you use a Spektrum transmitter (pretty much any one, DX, NX, iX) and set the wing type for your delta to "Elevon" or "Elevon B", you will find that the TX has, without so much as a by-your-leave, assigned channel 6 to flaps. It is highly unlikely that you have flaps on your elevon delta so you might reasonably think that Channel Assignment could change this but you would be mistaken.
Now, it could well be that you actually want to use Ch6 for, say, thrust reversing, canards, separate nosewheel steering, or whatever. Apparently you are SOL on this.
Spektrum's rather lame excuse is that this dates back some 15 years to an arbitrary decision, and they are unwilling to fix it for compatibilty reasons. Compatibility with what they won't say.
Anyhow, a rose by any other name etc., so just because the channel is named "flap" doesn't mean that's what you have to use it for. While you can't directly assign a switch to it for, say, thrust reversing, you can use the Flap System menu to assign the appropriate "flap" value according to switch position (just don't add any elevator offset) and that value will be sent to Ch6. Plug the ESC thrust reversing lead into the RX slot 6.
Similarly if you want to send an analog value to Ch 6 from a stick, knob, trimmer or sequencer, you can do this using the mixer. Just mix from the chosen source into FLP.
Awkward, inconvenient and illogical, but hey, it works.
