I am already discussing this in another thread in the "Multi-Copter" section.. But since that thread has gone of on a tangent, I wonder if its worth having a new post, in a better section, after all, this might help another user in the future.
I have just taken delivery of a Discovery and DX8 which I bought built built, rather than doing it myself as I was hoping that I was investing in the builders experience as much as their time.
But I am already regretting this, as its come delivered with the 3 position switch configured for GPS/ATTI/Failsafe and no manual mode. I want to add a manual mode, and move the Failsafe (RTH) onto a different switch and wonder if someone could help me.
I am pretty sure I understand the concept.. Instead of having a 3 position switch, set to 85%/0/-85%, I am basically 'simulating' a 4 position switch, using the 'mix' feature of the radio and 2 switches.
On the radio side, I know how to do this, as there are several Youtube videos showing how to do it..
But its the NAZA side that I am worried about. And perhaps even setting the failsafe mode on the RX.
I want to make sure that when I am done I have
1. A 3 position switch giving GPS/ATTI/Manual
2. A 2 position switch enabling RTH
3. The Discovery will respond to a signal loss and/or power off of the DX8 as a Failsafe and RTH
Is there a guide that I could follow which explains how to achieve this?
More importantly, how do I go about testing it? I assume that in the NAZA software (which I havn't even looked at) there is a way to simulate/observe all these conditions?
I am probably worrying about nothing and its easier than I assume, but I would like to know that there are others out there who have done this and can help me.

Edit: I should point out that there is little I can do for a few days, as the DX8 is going back because of a minor, but annoying fault on the roller.. Rolling to the right works perfectly.. But when you roll to the left, the 'click' and the switch are out of step, so the config changes before you get the click and often it jumps 2, or back 1 and its getting on my nerves!

as you say you have employed someone for their build skills and experience in setting things up.
im sure that your builder has set things up as he felt best, however, as this turns out you want something a little different.
First i would contact the builder and ask for his help and advice making these alterations. im sure he would be more than happy to help so your happy and would reccomend him to others.
Aitch ;D
You are right.. I am not blaming the builder.. They have set it up as they believe it should be. Personally I don't see why they would not add Manual mode since the DX8 has enough switches/channels, but for what ever reason, they choose not too... But I want Manual mode, if for no other reason than to give me a final chance of recovery if the unthinkable happens....
I have already been in touch with them, and frankly they don't care.. Instead telling me to look at Youtube where its explained.. So rather than make a silly and expensive mistake and doing this on my own, I am reaching out here as I am sure I am not the first to do this.
Is that not what a forum is for? At the end of the day, if my question gets answered here, its a thread that I am sure others will use in the future!
If you know how to do it on the Dx8 then you know how to do it. ;D
Load up the Naza software, youll be surprised how easy it is. With the Naza plugged in you will be able to flick the switches and see what each does. Then you can "trim" each switch in the software to make sure you are getting the correct selection.
Setting the Rx failsafe is slightly different, this is done when binding. So you need to have RTH (if that's what you want it to do) activated on the Tx, and then bind to the Rx while its in that state. Again you can test while plugged into the Naza software, but its best to test in the real world too. Either take the props off and test it or just turn the radio off and see what happens. ;D

Well that is very easy to do. Plug your Naza into your PC and run the Assistant software. The Assistant software will not allow you to arm the Quad, but it will show you clearly exactly what it would be doing if it was.
So once you have you mix done you can watch what modes the various switch positions put the Naza into, you can even adjust the mixes live while it is connected to the Assistant to fine tune them. Its a very handy tool, it takes the guess work out of the equation.
Setting the failsafe can also be proven on the Assistant without anything bursting into life, as long as your Spektrum receiver supports the failsafe feature. You turn off the radio, the Assistant will show the mode swap to failsafe if you have done it correctly.

The naza assistant has a blue bar showing flight mode, you can easily check switch positions give GPS/atti/manual and failsafe using that.
A second check you can do without connecting to a PC (so you can do this at the field, or before flying if you're unsure - with props off if inside the house), is with props NOT running, the LED will flash green/green in GPS, orange/orange in atti and no flashes for manual (between the 1/2/3 red flashes for GPS status). Failsafe will flash fast orange continuously.
Cheers all.... All good advice.. Will crack on one I get my TX back.
