Great idea Moses. But. . .

During my last AV job I was not able to produce any video footage that was usable

Is it possible to say you don't fly if it is windy?
What is the wind limit for decent AV ? ? ?

Please. . .

Ahmet,
You should stipulate that in the contract.High winds, no go.
I doubt you can get usable footage when it is windy to the point where you cannot fly smoothly.
I suppose it depends a lot on your heli size and weight and your skill as a pilot, but it is hard to give a figure.
15-20 KM/h with no gusts for a big machine like yours?
Just a wild guess.
DJI will help some but it's not going make it happen.

"Andrei all over the place. . ."
That was how my heli flew thru the turbulent air
Lets take this seriously please.

Ahmet, i wasn't kidding in my replies.
The "all over the place" reffers to my job.
I am a trucker over the road.48 states and Canada.
It was meant to be sort of funny as it can be interpreted in different ways.
I'm sorry if i gave the impression i was trying to make fun of your predicament.
To my best knowledge and personal experience, wind is the worst enemy of anything capable of flying, be it full scale or model or bird.
You should know there are no set rules or valid theory regarding flight in windy conditions, except maby that is better not to do it.
Your heli is pretty big so it should handle winds better than a Trex 450 but it too has it's limitations like most everything.
Again, i apologise if i gave you the wrong impression.

Andrei,
I thought you were from Russia, the name Andrei. Sorry
When I wrote
Lets take this seriously please
I was not upset at all. So, no sour feelings.

Back to lousy flying in windy conditions. This was during my recent assignment 500miles out of Istanbul. The day started quite windy and I was not able to decline the customer's request to do the job. We were to film this geothermal energy station.

Naturally the heli (my e converted acrobatic with funny retractable legs) was not holding a straight course. I had to give corrective inputs and it showed in the video. Especially when flying over the structure the wind played havoc and pushed the heli 50m skywards. It was all over the place and I was panicking.

Then, I took out the old trusted gas bird with HC. The end result was a lot better but this time we suffered engine vibes which I was not able to get rid of. This tells me that for AP HC or a similar flight stabilization is a must. For me anyway.

Ahmet,
I am just a passionate FPV-er and occasionally record my flights, when the scenery is breathtaking and i feel it's worth trying to get some meaningfull footage.
I am using a DJI wich helps me a lot as i often try to fly by intruments and it allows me to concentrate on monitoring the OSD parameters.
I think all autopilots or whatever the flight stabilisation devices are called,are reactive devices and no matter how well tuned and properly set up they are, there is a brief lag in reacting to a vector and also a very defifnite limit to how much they can accomplish in holding the heli steady thus especially in gusty winds the heli will fly far from rock steady no matter what.
When you flew in proximity and over the station and hit turbulences created by it,the HC helped as it has faster and likely more precise reaction and correct inputs than your eyes and thumbs so the flight path wasn't as bumpy as with the first machine but still probably not anywehre near as on rails.
I suppose you can get away with the vibes from the IC motor for photography but i doubt you can ever tame them enough in order to get passable HD video without tedious post production.

I hope you can still use the footage after all the trouble you went through, driving so far away and having to deal with the least ideal flying conditions.
I dont think i would've had the guts to lift off in such strong winds.

Andrei from USA

PS. You were not far from the truth in your assumptions.
I am of Greek oringin, born and raised in Romania, and for the past 20 years (just about half of my life) i've lived happily in the Land of the Free and Home of the Brave, and i consider myself a true blue American.

Flyingcam just fly with almost no wind conditions!

From my experience good results for video can only be obtained with very low winds. Speaking about a professional shoot obviously.

For photography we fly with almost any wind!

Hey folks, we are getting there slowly.

Andrei, do you know Georghe Hagi? He is called Maradona of the Karpats. I beleive he was a much better soccer player. He played for Galatasaray (which I support) and he was in the team that played the European cup final 200?).

It is very difficult for the customer to realize that aerial video footage is only good when there is no wind. I have been in this situation many times. Can not produce smooth video, then you are no good. That is it. . .
The producer sells his stuff with aerial video in it. Then they just pick a date for video and then ask you to perform on that date. I try to explain the situation and they say ok no problem. They only realize that they can not get the footage they need at that last moment.

Considering that it is usually windy most of the time how can we say we don't fly when there is so much wind?

What is the best way to go?

A special thechnique to video during windy conditions?

Or a special setup?

That is what we should be after. Yes?

If I consider my self an AP pro I should be able to produce acceptable video in any condition.

Let me know what you think please.

Ahmet,
Of course i know Gica Hagi.
He was probaly the best soccer player Romania ever produced.
And most likely the best known internationally..
I almost got the chance to go to his wedding by the Lake Snagov, sometime in late 80's.As a friend of a friend of his.
I dont remember what prevented me.
Soon after that i escaped to Yugoslavia and became a UN refugee.
About the omnipresent wind, all i can think of is symmetrical blades, high head speed and a good autopilot.
And lots of practice.

Andrei,
you definetly been thru some tough times when you were much younger eh? You did well and I hope you got what you were looking for. It is very interesting to read about other peoples extraordinary stories thru this forum. Thank you for telling

I am 54 and I still live in the same house I was born. It must sound very boring to you

Any way, a lot of practice (some crashes included), a perfectly tuned AP platform, steady flying and electronic stabilization on both the camera platform and on the heli should help a lot to get the best out of those situations. I expected some one to come out and suggest something we have not heard of so far. They must be hiding or they are not aware of this topic.

How many calm days a year for perfect aerial video? What are the chances AP video jobs will coincide with those days? Not many. . . You see what I am getting at?

I will post if I find something interesting.
Cheers,
Ahmet

Ahmet,
I think you are a fortunate man to live in the same house/town you were born in.
It's kind of sad when someone has to look for a better life elsewhere.
And not easy at all.

One of the reasons i got the DJI is because it does have camera roll and tilt compensation and it does help a lot in keeping the camera pretty steady.
And it makes flying so easy, you can concentrate on framing and other chores instead of sweating bullets.
But when it is gusty, the heli will jump around a bit.
I tried some time ago an HC Profi (after owning 3 HC Rigid) but it was too difficult and time consuming to set it up right and i gave up fairly quickly.

It may be more configurable and ultimatley maby it is a superior device but the ease of setup and use of the DJI i doubt it is rivaled yet.
Darn i sound like salesman.
Let's hope there are some other more experienced flyers who could share some of their experiences and tricks regarding flying in high winds.
Hasta luego, as they say in New Mexico

Never had good results in windy days.
Image stabilization make good job but the customers dont like it.
I dont have but, i think a good mechanical setup in gimbal plus roll function with electronically help maybe make the job better..

Ive flown my 30 size heli with undercarriage on a day where it was blowing 20-25mph. A little gusty but it did fine.

Just be sure you keep in mind which way the wind is blowing,
watch out when you go down wind. Youll slingshot in high wind.

But its not too hard to fly in if your just hovering most
of the time.

Since stable aerial video recording in a persistently windy location is basically impossible, you can rest assured that the competition can't out-do you. Just my USD 0.02

I have flown the DJI autopilot in some stiff winds and it's attitude moves around quite a lot in order to stay in one place.

Going flybarless and smaller blades can help. But the wind is tough to deal with....

My experience with flybarless rotors was quite the opposite.
Gusty winds make the heli buckle like a stallion when he senses a mare in heat nearby.
