Intermittent Naza Fault

[dp106]

Rather a strange one this..

For the most part my Naza behaves itself just fine, (no GPS fitted).  However on the odd occasion when I power up and go to take off the rear doesn';t want to lift.  (I fly FPV and usually take off in manual).

Last week when I was testing a recent rebuild I took off in attitude mode and it went mental.  Pitched forward straight off and flew straight into the wall.  I';m thinking this is the same issue I see occasionally in manual just a bit more exaggerated when in attitude mode!

Anyone else seen this?  I';m a bit worried I';ve had one rough landing too many and there';s something not quite right with the Naza

Web page just crashed posting this, damn!

I';ve seen this issue crop up a lot on this forum lately, it sounds similar to an issue I had happen to me twice several months ago, back in early summer.  Looked around on the forums, came up with a sticking sensor in the Naza.  Cure was a light ';tap'; with a screwdriver on the underside of the Naza FC.
Odd, but afterwards it hasn';t happened since.  I was transporting my quad on the rack of my pushbike in those days, loads of vibes, must have corrupted he sensors maybe?  It culminated in my quad ending up high in a tree, sans lipo and with gopro in the river below!
Worth a try eh?

Eek, not sure I fancy the idea of giving it a tap  (I';ve always wanted to use the smilie  )  I guess if as you say I use a screw driver there';s not too much danger of applying excessive force..

The main Mems sensor in the Naza is not hard mounted. It sits in between some foam dampers.




Note that in both these photo';s the Naza unit is upside down.

I guess, given a hard enough shock it would be possible for it to stick in a strange position.

Yo!  I';m not suggesting you hit it with a hammer!  All I did was to tap it very lightly with a flat bladed screwdriver a couple of times on the case, just enough to unstick the sensor.   I think a tech from fpv.co.uk suggsted it on a forum somewhere, but don';t quote me.

haha, I';ll send you the bill for a new Naza when I';ve squished mine with a big mallet
