There could just be an AXN maiden this afternoon!

Definitely agree ... the air is MUCH smoother higher up especially if it's blowing off trees etc.

Sometimes you can launch into gusty winds and have the calmest flight ever 500ft ... er, 400ft up.

Shirly, you mean 999 feet...
:P
There really is no neede for this carnage...
Snooze, where are you?
If your'e anywhere near Cambridge, I'd gladly meet up and give you a hand next flight.

I don't have insurance at the minute so am not subject to an exemption :D

[FPVSteve]

Making me miss my AXN - this was my first one, fitted with a Cyclops CE-OSD and a pan servo with the worlds poorest FPV camera :)

! No longer available

Great fun - I remember the lipo being slightly warm after this flight despite the temperatures lol 107km/h max on 3s battery heh :D

Man, my FPV has gone backwards and boring instead of better.

Sorry, I'm up north near Chorley, Lancs. But thanks for the offer. I appreciate it.

So let me confirm so I can start doing some searches. I need to mix in 50% rudder to my ailerons and knock my expos down?

No, thats way too much I suspect....it depends how much Rudder movement you have, but as I said, if I just breathe on my Rudder it will respond immediately.
  I would suggest you mix in just 20 percent Rudder and try it....The ailerons on the AXN are very mushy, especially around neutral...In fact mine is trimmed to cruise straight using Rudder trim only because the Ailerons dont do a lot if you throw trim on them...


Good luck....:)

Thanks. That last couple of lines of your post took a few reads to understand but it sank in eventually. I noticed the same the evening I built the AXN, I was mucking about with aileron trim and they didn't seem to move at all.

Would you alter the expos?

Thanks

  I never use rates or Expo, I like a more linear response and usually set my models up with a bit more throw than I need...Its just a personal preference, yours may be different.
  Dont be afraid of movement on your Ailerons though, as I said, they are not very responsive.
You may well find yourself trimming the AXN on the Rudder only....Be aware, of the motor thrust line though and the trim change if you open the throttle fully.
  I trim mine to cruise around 50 percent throttle, as flying FPV is comfortable at this speed...expect the trim to change with throttle movement.
  When you start flying FPV regularly, you will notice how sensitive the Rudder is, even just a few trim clicks on it will show up in the Cameras view... ( which is a good thing)....:)
  Next time out, chuck it up a bit and get on the elevator to gain height, keeping the wings level...LOS of course to begin with...:)

I'll go away and try to digest   :o

I've turned the elevator curve down a bit as any movement on the ailerons is causing the elevator to move. Gotta say, the ailerons on my AXN have a fair bit of travel. I've got the control rods in the middle hole ... As per xjet's build series.

After my maiden crash yesterday I decided to check the geometry of the rudder. It seems theres about 3 degrees of movement  more to one side. Im taking a guess here that id better check the servo horn many moved.

Why would your Ailerons moving also affect your Elevator? Do you have them mixed together..?

  I would not worry unduly about your Rudder movement, just be aware, it does not need a lot at all, say 6mm throw each way.

I think the elevator is moving slightly because any tiny movement above or below the centre line of the right stick is  sensitive to the elevator ... of that makes sense.

I'll keep an eye on how much rudder is needed. That's great advice. Thank you. I've also mixed in 20% rudder.

I've checked CG again. All good to go .... when there isn't any wind!

Thanks for all of your replies.

20% rudder as already posted is about right.
Some transmitters allow you to alter the spring tension on the sticks which helps with inadvertent movement on the wrong axis. I have also seen a rubber band mod for the seriously heavy handed.

[Dillwhacker]

Just a couple of random thoughts...
Make sure your aileron - rudder mix is working the correct direction - right stick = right aileron up = rudder to the right.
If your elevator seems sensitive to tiny movement at mid stick, make sure your expo is working as you want....Spektrum uses positive expo to mean 'softer' in the middle, but I believe some radio manufacturers use negative expo to mean this...
Good luck !

I should be flying near Tarleton tomorrow afternoon if you need a hand.
