So I splashed out, and a QAV540g is on it's way  :)

I have only messed with a phantom before, so never actually built a quad before so I thought I'd start a thread to log my build and ask questions which I hope you fine folks will answer.

I'm not in a rush to finish the build, it'll have to be done as funds allow, but so far I have ordered:

QAV540g
Carbon Landing Gear
Lumenier 30 amp ESC with SimonK Firmware x4
FX4006-13 740kv x 4
Lumenier 10x4.5 Carbon Fiber Props
LayerLens for GoPro 3

And I have a new Naza V2 with GPS.

So first stupid question is:
Lumenier suggest the alexmos board for the gimbal, but I get the impression tuning etc can be a bit of a holy grail, I have a Tarot gimbal on my Phantom which is ace, if I bought another Tarot board and installed in on the 540 would it work?

If your using a GoPro 3 then yes the Tarot gimbal will be fine
Education and schoolin is good, but FPV is gooder :)

Mudders

Sorry, to clarify the board will run the 540g's gimbal motors?

No I said gimbal :) If you used the gimbal with controller it would work, using other hardware is totally different, the driver chips are very small so might not be able to cope with bigger setups. They might though, but you would be starting the PID process all over again just like with tuning an ALexmos setup
Education and schoolin is good, but FPV is gooder :)

Thanks for clarifying. Alexmos it is then.

I have a 540G. The build is reasonably simple. Just look closely at the manual when you build the gimbal. The holes for the pivots are not central fore and aft.  The holes should be closer to the front than the back.

Any questions, post here or pm me.

Cheers guys, I spent the evening putting it together, gimbal built, dirty frame with esc's installed, motors bolted on (me likey the fx 4006 jobsters), clean frame bolted up and all put together, I'll do some pics in the morning.

Easy so far, the only thing I have and haven't installed is the Naza, is there an optimum position for this?

One thing that I forgot to mention, never pick it up by the clean section.  Always put your hand underneath and pick it up by the dirty section or you will strain the orange bobbins.

If you do manage to separate a bobbin they can be glued back together with thin cyno.

Thanks BO19, It's dead on the CG now. Good tip Simon, that sounds like a sensible habit to get into  :)

Here are some naff piccys, I can see why people wait to get all the bits before they start, I'm waiting on some cable sleeve, it means I can't finish much up untill it arrives  :(


Mudders

While on the 'things to get' thought, I gotta nother question.

I think I'll go for this flight cam Lumenier CU-690 Ultra - 690TVL Ultra WDR

So, Ezosd or Naza OSDmini? I like the neat idea on the mini just clicking into place, but the Ezosd has a current sensor which everyone seems to miss when they switch?

Hi folks,

I'm really hoping you can help. On Friday I took delivery from Getfpv of a spanking new 540g, Lumenier 30a esc's, the new fx motors etc.

I built it as per instructions, set up the Naza so everything looks good to start (the only thing I haven't touched is any gains).

When I turn on all the lights do their stuff, GPS lock etc, problem is I can't arm the motors!

I have plugged each motor directly into the RX (spekky 9ch dsmx) and set each hi and low point on the throttle, each arms and works ok.

Back to the Naza and nothing, no arm sound nada.

My question is, have I set up motors/esc's up correctly?

Once the hi/low throttle setting is set does the esc remember it?

I assume I should hear the arm sound on start up?

I hope I haven't got a dodgy Naza  :-\

Help!

I should add that when the naza is on, If I remove a esc and push it back in it makes the arm sound.

IIRC you can set the motor idle in the Naza software. Try experimenting with different settings and see if that helps with arming.
It also helps to calibrate the receiver in the naza software (centerpoints, 'throws' etc.)

Usually you should get at least the startup sound form the ESCs (the one where they count the cells etc.)
