Would windy conditions affect the barometer?

[Allanm]

I took my 450 quad out for its first real flight today. It was a lot windier on the field than it was at home, but, I thought I may as well have a fly.
I waited a few minutes to make sure I had a good gps fix ( steady green light for at least a minute) then had a fly around.
I mostly flew facing into the wind which was around 10-12 mph and gusting a bit more. All the time I was flying, I had the right stick pushed forward a tad to counter the wind.
I tried alt hold at about 15ft up, the quad almost dropped to the floor then raised itself but it was bobbing about quite a lot and i could hear the motors working hard everytime it dropped a bit.
Next, I tried loiter. Again, it was bobbing about and looked like it was climbing stairs and getting pushed downwind. I turned off loiter and brought it back to me.
So, a couple of questions.
How windy is too windy to use loiter and alt hold and would the right stick position affect it when its engaged? When it was in loiter, I didnt see it trying to get back to the spot where I switched it on, but it didnt shoot off as I have seen them do when they havent got a good gps fix.
And, would a high wind affect the baro?
The barometer is covered in a piece of foam and the whole lot is covered in shrink wrap ( its a Peter King quad) so I wouldnt think the wind or light would affect it.
Obviously, I will try it again when the wind dies down a bit, but I did get a pretty good alt hold position a few days ago on a calmer day.

The sort of winds we had today would most likely have an effect, my mate flew his today - a 330 size with KK controller in acro mode and he ended up walking across 2 fields to fetch it back! I then chickened out with mine and had a go with my Wot 4 instead - it was great fun!

on my crius board i have some breathable foam covering the baro as even prop wash can effect it

Wind / Prop wash / Light  will all affect a baro

Is the foam the breathable type  Hold over mouth..see if you can breathe thro it..if not..wrong foam!.
Shrink wrap?...if it covers the Baro it may not operate.

Yes it';s the proper breatheable foam and the shrink-wrap has holes around the board for all the connections and it is pretty loose at the top. I am sure the build is correct, this guy builds loads and they are all flight tested before despatch, so I guess he has got it right.
First time I flew with Alt Hold it was far less windy and it worked fine. I was just wondering if the high winds would have affected it.

It doesnt matter how well your baro is setup strong wind is still going push the copter up and it will fall as the wind varies in strength, the newer arducopter that uses the acc for altitude hold would resist the wind much better

Thanks Gaza, that sort of confirms what I thought. Maybe if I had left it in Loiter it would have started to get back to its original position, but as a new pilot, I could see it heading away from me downwind and I wasnt sure I could get it back!

Great fun though
