Naza return to home.

[CurryKitten]

I've no idea what smart bind is either - what's smart bind ?

Example of what you do with a FrSky rx which is what I use to set fail safe, is on my radio I switch my manual RTH switch on and set throttle to 50%, then I press a button on the rx.  If the rx looses the signal from the radio it then sends this signal to the Naza controller - which obliges by coming home

[Randall]

The rth works great on the Naza i have it on a switch and also if i turn my tx off it kicks in (so loss of signal would activate it) i have turned the tx off and it does work fine however you do need to set this up first using the software on the pc is easiest.

One thing is i find the 20m climb a bit hit and miss it does not always climb to 20m i have set the rth off when and 2-3 feet and it only went up 8-10m and would not have cleared a big tree for instance. So dont rely on it but id at a decent hight it will work a treat. I have used mine once in a real emergency and it was great to see it come home all on its own.

Smart bind is a little different to the normal bind and allows you to have an almost infinite variety of failsafe options on 2.4 systems.

Put the bind plug into the receiver and power on as normal but now remove the bind plug.

When you power on the tranny into bind mode- whatever position the switches and sticks are in will be the remembered failsafe position.

Is that the equivalent of pressing the button on the FrSky rx (having moved the sticks/switches into the desired postions) in order to set the failsafe position then ?

[Skipper Billy]

Not familiar with FrSky gear but it sounds the same. It works with Spektrum and JR etc.

[Heliotrope]

Not with the Naza, as I said it'll rise to 20m before coming home, or if > 20m already just come home at that distance. It's also giving you the chance to reestablish an RC link, there's a pause before each of the phases - so on initial control loss, it'll sit there.. wait, then go up.. wait, then come back, wait and finally land.  I believe the WooKong has the return altitude programmable... but it's lots and lots more money.

I know it sounds pedantic but the devil is in the detail as they say. Is the RTH altitude based on the altitude at take off point or the point at where the RTH is invoked? It may not matter much in Norfolk but it does here in Wales!

[Skipper Billy]

If you invoke RTH at less than 60 feet higher than where where you took off from it will climb to 60 feet then fly home and descend.

If you are higher than 60 feet from where you took off from when you invoke it it will fly home at that altitude.

The NAZA is not aware of your terrain.  So it will climb to 20 meters above ground level from where you connected the battery.

Many thanks guys - that's clear now.

Here is a question. I thought I had my quad set to come home and land.

I flip the oh shit which to call it home and pull back on the stick. I have to keep the stick down or it will not come home. Problems is it won't land and it over shoots home and carries on unless I let the stick go to get control.

Your thoughts please....

[FPVSimon]

It sounds like you hit the IOC switch rather than the RTH.

[JezUK1]

Silly question what does that stand for?

[CurryKitten]

IOC = Intelligent Orientation Control

It basically means in this mode, pulling back means come back to you - irrespective of which way it's facing... not used it.

Here's the thing, when you engage RTH, you don't need to pull back on the stick... in fact doing that will do nothing, unless you take it out of RTH.

Load up the Naza assistant and check what flight mode it goes into when you flick this switch... because it certainly doesn't sound like RTH is engaged

[JezUK1]

Strange I'm sure I had it set correctly. I'll have another look and report back.

[plingboot]

I might be wrong, but I didn't think the naza could be set up with an rth switch like the WKM.

On my naza(s), I've set up a switch which forces the flight mode into the failsafe zone, via a mix, and also uses a throttle cut function with an offset to fix the throttle at a bit below 50%.

in the assistant tx monitor it works as planned, but not had the balls to try it for real yet. Maybe this weekend.
