Naza-M Lite set-up

[AirPix]

Hi, all--

I've built and flown fixed wing RC aircraft for many years but this is my first (ad)venture with rotary wing. I;m building a Gaui 500x Photo Ship equipped with a Naza-M Lite flight controller with GPS.

I use a JR XP8103 with a Spectrum 5.4-gig module. This Tx does not do switch assignments happily and I may resort to a programming tap-dance or hardware mods to get a couple of switches on Ch 7 or 8.

What I need to do are 2- or 3-position switches for the Control Mode and the Intelligent Orientation Control functions.

Control Mode: the available settings are: Manual | Atti | GPS/Atti Would I ever need to drop into the "Manual" mode? I'm thinking that I could do with a 2-pos switch here.

IOC: the available settings are: Off | Course Lock | Home Lock From my readings, I think I'd need to be able to select the "Off" mode, and that would require the use 3-pos switch.

This shouldn't be difficult, but I'd like to verify the DJI/Naza definition of a "2-pos" and "3-pos" switch. Mine is (-100% to +100%) (1-2) for 2-pos and (-100% to 0% to +100%) (1-2-3) 3-pos.


Thanks,

--Bill

Hi Bill You do need to have manual mode selectable so that you can do compass calibrations at the field if they become necessary. I have GPS, Atti, and RTH set up on my 3 position switch and I am able to select Manual by changing the travel on the gear switch so I can do a calibration. I have Course Lock 0n/off and Home Lock on/off set up on two other switches but honestly, flying FPV, I never use them....

FlyGirl - did you program fail safe?

Hi there! Yes I did....

Hi, Fly--

Ah, OK. So I'd need to toggle between Manual->GPS several times to go into the Compass Calibrate mode, if I needed to calibrate. Sounds like a rarely-used function.

From reading the manual, I don't see how you can set up GPS, Atti _and_ RTH on the same 3-pos switch. Isn't RTH ( "Go-Home and Land" ??) an Enhanced Fail-Safe function? Can you even set up "Course Lock 0n/off" and "Home Lock on/off" on separate switches-- the manual seems to suggest that Course Lock and Home Lock have to be controlled by the same switch.

Or is this a Fail-Safe question?

I don't know about others on here but I calibrate my compass maybe twice a month just in case of drift... I did have one time when I noticed some strange yaws and when I brought it down and recalibrated it, the yaw issue was gone.

RTH is used as the failsafe mode yes, however failsafe is activated from the receiver and not the flight controller. You tell the receiver when you first bind it where the sticks and switches should be set if the receiver ever loses signal. If it does lose the signal then the receiver commands the flight controller to switch from whatever mode it is in to RTH mode and fly back home.

For Course lock and head lock on and off, I have two switches mixed. I have to do that because I only have a 7 channel radio. What you say about having separate switches may be true but since I have a 7 channel radio I can't be sure.
