I have Copterworks AF25B and will be mounting Ace One to it soon.
We have been asked to to few jobs, where we need to fly 300-500 meters quite fast. So the only thing we see option is mount a FPV camera and fly with a monitor.
Can people tell my pros and cons, why am I not seeing many doing this in arial film work?

Those 300-500 meters obstructed or clean Line Of Sight?

The Copterworks AF25B is a quite big helicopter, if your LOS is clean from obstacles you can fly 500 meters in a line if you stand (the pilot) in the middle of the trajectory without the aid of FPV equipment.

It is not clean line of sight, and the pilot will not be able to stand in the middle... :/

Is people in general using fpv when filming? Is it possible...
Whether we will usit for this job or sometime later...

Be careful doing FPV with big helis. There are better ways, the best is to use a chase vehicle so the pilot is never out of line of sight.

A screw up with a large A/P machine using FPV that gets some press attention could really have a negative impact on the rules that are being written and decided on right now, especially if you are partially relying on the DJI for control. At the very least only do this in a very controlled area where there is no one around. (edit: I see you are not in the USA so maybe an accident won't have as much of an impact on the FAA rules but my point still stands)

Example: Another "professional" (who I won't name) was flying FPV at a ski resort, trying to film an event without permission, lost control/signal and crashed near the open public. Later that year we were hired to film an event, working closely with the event organizer and the athletes, but we were severely restricted on where we could fly due to the resort's experience with the other crew. That was really frustrating for us and our client because we were flying very safely using line of sight only, doing short follow shots in a small closed off area. But it was impossible to explain to the resort staff the difference between what we doing and unsafe FPV the other guys were doing. Essentially the other crew ruined it for us and our client by flying unsafely and over the open public using FPV. The most frustrating part is these guys actually advertise that they will do FPV filming for hire on their website!

Thank you for your response. Here the rules are quite loose, and we would like to keep it that way There for I will not be taking any changes.

Is FPV unstable system ingeneral?

I suggest you test FPV using some cheap multicopter or heli with stabilization first, so you can see what level of equipment will be required, and how difficult it really is to track a subject and get a good stable shot with FPV. 500 meters isn't far but you need 100% reliable connections (downlink and R/C control). Since you mention you don't have direct line of sight then the it will be much harder to get a good signal.

Some shots are better left for the full scale guys. If you use your helicopters strengths and avoid flying outside of the envelope you and your client will be happier in the long run.

Thank you for your response! I´ll do a test on my small coper.
But I think I´ll use a chase car for this job...

if you're going to FPV it, i would say you'd almost do better with two people operating it, put one cam on your pan/tilt and another fixed on bore-sight for the pilot to fly by, and have a second person operate the swivel cam.

I'd say.

An FPV-equipped model must be flown by two AMA members utilizing a buddy-box system. The pilot in command must be on the primary transmitter, maintain visual contact, and be prepared to assume control in the event of a problem.

Be carufulll with fpv style with heli's it is very dangerous.
The safiest way for long pass is a second pilot.

I´ve never heard about second pilot.
Can any one tell me more about that kind of system...
Is this a kit that I can buy or something?

I don't know if it is a "plug and play" system in the market.
Before two years we collaborated with one university and make one for us. It is a simple one receiver who can receive information the same time from two transmitters.
The project was for a long distance off road car, live event (Rally Acropolis).
The maximmum distance for "our" shooting was 1200 meters so one pilot stand to the midlle of the approx. half distance and the other to the other half at the end.
The heli has starting a straight forward flight for a 500 meters, at this point the other pilot take control and continue the rest distance to make the return circle. It sounds easy but believe me when you are playing especially in live event it is very hard!
Also do not forget 500 meters it is very hard to see your heli.

Sounds really interesting. Where you using 2.4 GHZ transmitter?

72Mhz
2.4 Ghz and 5.8Ghz it is poppular in live events plus the enginering team say it is difficult to convert a 2.4Ghz than 72 or 35-40

I think it is easy to bind two TX to one RX in 2.4Ghz system but i don't know if can play. I forgot to say, when one pilot have the control the other TX cannot sent any signal until first pilot hits a switch and bidirectional

Thats good point about test/training fpv with lighter and safier copter but, Copterworks machine is a large sigle rotor heli and has different characteristics in flight.
I have almost 25 years experience on RC aircrafts and the last 12 on helis, and when i try to fly a simple airplane NOT a heli i crash it in a few minutes. In other hand it is the ACE ONE. All the autopilots who can find everyone in the market, are not guarantee about electronic or mechanical failures. If you flying directly with your eyes you have a knowledge about your persons or trees around you. In case of monitor flying the thinks is very very different.
Andri, have you ever try to fly your older models with fpv equipment?
In case of two pilot flying (if you find this solution with two Tx's)
Have you ever try to fly the AF25B in long distance?
It is extremly dangerous shooting with large heli's in this range
i heard only two persons who try it. Emmanuel from Flying-cam (1st AP company in Universe) and Philip from Hovercam.
Our trying to fly with this long distance ends with good results, but i will never do it again.
I prefer to lost one job than killing someone.
Before 3 years, my co-operator makes a short shooting for a local event without my permision,.When i heard about this next day i fired him. After a week Greek FAA see the video on youtube and call me.

Really what is your experience with Rc helis?
I see your website. Are you collaborate with this company with AF25B or are you the full scale pilot?
