Here is 360 pano and a couple of shots, I did these flying FPV. It's amazing how easy it is to do these panos in FPV , just shoot an pirouette.

Nice shots Where were you in relation to the heli? Are you in that large image?

Cool How would these flights differ from flying up to height normally and then checking the downlink and adjusting the composition? Did you just fly into the position using just the downlink? I guess in many ways that's what I do ... although I usually just glance down to look at the downlink every few seconds or so ...

Well, it got you the shots you needed anyway Good work!

Well they differ in that the heli was almost invisible at that altitude/distance and also one flight is enough to get all the angles you need; I can travel 1Km in any direction , frame the picture and fly back,


I flew 100% fpv from takeoff to landing

I'm using an FMA FS8 receiver (no complaints) and a Futaba 9c.

I did get sort of lost in the middle of the flight though, I couldn't find my reference points, I believe it happened after piroueting three times in a row for that pano

i just have a OSD on my desk with gps and a direction to home base.

that could be helpfull.

i just demoed the unit to some buyers from hobby lobby at the Nürnberg toy fare last friday. could be that they will import it.

Thanks Torsten, I have been waiting for those but they are still out of stock.

Cranester thats some amazing shots.

I'm going down the FPV path here, still putting it all together on my 3DX450. I too want to go 100% FPV.

I've gone with a 7 CH 5.8GHz downlink, twin 5.8GHz RX's,with 2x 8dbi patches, Oracle diversity, LCD glasses and DVR.

Theres a post elsewhere asking for advice about first time FPV, if it's just experts only, or can first time FPV'ers get to grips with this type of flying.

Be interested in your thoughts, seeing as you appear to have this type of flying nailed good

I don't mean to rain on your parade, but I just have to say this. FPV is EXTREMELY DANGEROUS! I know you guys think it's reliable and predictable, but it's not. RF is a fickle beast. Most downlink systems are cheap and unreliable. Many are not even tested in the U.S. and not F.C.C. approved, not to mention the fact that it's against A.M.A and F.A.A. rules to fly FPV only. I know that doesn't apply to those outside of the U.S., but the same problems arise. Even the best systems out there can not guarantee complete reliability. Especially when it comes to interference.

Just imagine, you're flying up there at 400' or so, and the downlink looks great. you're doing a slow piro and then wham, no video. The downlink is gone, and you have no idea where the heli is. Now it's in UNCONTROLLED flight at this point. Next thing you know, it comes down in a school playground, and kills two kids. You get arrested. They confiscate your equipment. Now the government is going to charge you, and the kid's parents are going to sue you out of existence. You have to live with this mistake for the rest of your life. You've lost everything. Why? Because you relied on a cheap downlink system to fly FPV exclusively. Don't think it can happen to you? Just ask a couple of people on this board who have had that, or a similar scenario happen to them. Wait, you can't because one had to leave to hobby forever and the other comitted suicide.

Just remember that there are always two sets of consequences for every action you take. Those that are INTENDED, and those that are UNINTENDED. You can't always control these.

And people wonder why we are getting so much attention from the government these days.


I'm not trying to tell you what to do. It's your choice. But PLEASE be careful with this stuff, and always have a way to view the heli without the system if possible. Someone's life or property may depend on it.


Stepping down from soapbox now.

Thanks for the reply cwd10. Yes I have fully realised the dangers.

Thats why I will be flying in a huge empty field, miles from people. The RF gear is good quality, not ebay junk, (I design RF video link systems as a part of my work).

I'm not looking to do long-range flights, although I've managed 1.1km on 2.4GHz 10mW, static LOS test. The 5.8GHz system I have is much better than that. So for my short-range requirements, I should be good to go.

With the LCD glasses, I can look 'over' the top of them to see the heli directly if needed.

My enquiry was more to do with the practicality of FPV flying.

But I take on-board all the comments, and I thank you.

HeliEye:

Yes, based on your qualifications, location and equipment, you are better prepared for FPV than 99% of the people on this board. But there is always a risk. It's seems as though you have mitigated most of the risk, but you are the exception here, and not the rule. My post was for the benefit of everyone here, so that they can learn from the costly mistakes of others, rather than their own.

As to the practicality of FPV. Well it depends on many factors. Intended result, pilot skill, equipment, camera type, etc. Yea, it can be a great tool. I only use it for brief glances to frame still shots, as most here do. For long range, high altitude stuff, well that's the scary side of this. I'll admit that seeing decent quality video in high speed FF is really cool, it gives me chills to think of the possibility of disaster. It's one thing on a slow stick or a foamy, a whole different ball game with a big heli.

Good luck, and be careful.

Hey Cranester, do you have any kind of Heads Up Display on your downlink video to help keep the heli level, or that gives you altitude, or heading, or GPS back to home? Seems at that altitude it would be very difficult to keep the heli from drifting all over the place on you.

Those pictures are incredible!

Thanks

Beautiful shots Juan.

There is another safety net for FPV AP/AV.

Having a 2nd pilot with a tx on your freq or spektrum sig channel.

You fly FPV. He/she is the spotter/backup pilot.

That is something I'm working on with my camerawoman.

Laying out a set of main/backup flight paths, elevation ascents/descents, framing points and calling them out to each other so we both know where we are ..well.. let's just call it a work in progress

We've practiced me flying FPV while we go through the path points and then when we hit the one point at alt, I turn off the screen and she takes over flying. We've done this in a human-less environment (ie. mountains/open terrain) at 350'. It's been and continues to be quite the learning curve.

We started with a cheap foamy glider/easystar for testing and swapped over to the beater rex600.

... But honey it was only $$$

Second the previous post about a second Tx if you have someone qualified to do it.
The FPV is a an ideal situation when everything goes perfect, but for that one time it doesn't I think you are better prepared if you have a spotter with you whose tracking your heli and can point it out to you immediately for recovery if it fails.
