I find that flying in ATTI mode in windy conditions both improves my flying and makes for great stable footage. The GPS mode is a great tool and I do not want to miss it at all. Being cogniscant of what it does for me makes me a better pilot. With GPS mode it is just too easy to totally forget about the wind and I consider that a bad habit for anyone flying anything in the air.
After I had flown about 15 hours I decided to take the plunge and change my P2V to NAZA mode. This is described in the manual and in other posts. It can be un-done just as easily as it is done. I have configured it such that the S1 switch 'down'' means 'Failsafe'. I do not intend to set that to 'Manual', ever. I did not buy my P2V to do aerobatics. I use a simulator for that. But I digress.
The advantages of flying in NAZA mode for me are:
* Ability to instantly switch between ATTI mode and GPS mode
* Better LED feed-back about GPS reception during start-up
* Ability to switch on 'Failsafe' without switching off the transmitter
* Ablitiy to instantly and positively switch out of 'Failsafe' at any time
* IOS Home Lock Mode for recovering 'lost sight' manually without the aid of down-link
* Much more stable footage in high wind conditions in ATTI mode
Flying in NAZA GPS mode is just as flying in P2 mode with green LEDs. There is no difference. Just make sure your S1 switch is all the way up. I make that part of my periodic 'scan' of things. It becomes a habit, just like flicking it up when things look wrong.
Here is what I did before changing that switch to ATTI for the first time: I went to a very very open field under a blue sky with about 10 knots of surface wind. Something like this where I practised yesterday:
It is important to check the weather and pick the right time. Note the front approaching on the right. It was blue skies with ~12knots wind when I practised. An hour later it was no-fly with rain and high gusty winds. Also notice the nice straight line features of the terrain, great for practising precise control.
I took off in GPS mode with 10 sats, did my usual figure 8 and hover close-by to confirm GPS stability. Then I took it up to about 100ft and flew up-wind from my position and let it hover. Then I switched to ATTI and watched it drift without any control inputs. Of course the wind was stronger up there and it took up quite some speed, much more than I had expected. I let it drift a short way down-wind from me and switched back to GPS. It stopped and hovered almost immediately. After repeating this a few times at different altitudes and noticing the wind shift I started to fly it in ATTI mode. I brought it in close to be 100% sure about its orientation and first tried to return it to my position. Depending on the gustiness of the wind it can be tough. Whenever I got uncomfortable I switched back to GPS and re-positioned up-wind again. Gradually I improved my skills and I will continue to practise for a long time to come.
Besides the better footage I get when it is windy this practice gives me confidence that I can handle a situation where GPS suddenly becomes unreliable or some other bias appears. I feel that it changes my instinctive reaction to something unusual from freezing and likely releasing the sticks to actively flying the aircraft against the bias. I consider this a good habit. Hopefully it will give me enough skill to recover from the infamous 'fly-away' if and when. Staying in the GPS comfort zone will very likely not prepare me.
This is my experience. Your's may vary.
