    seriously why is this thing so expensive.

    the radio, def not that great, the drone, where are the bells and whistles?

    Give it a year and it will half price like every other unit they have made. Actually six months down the road people are going to be pissed that they paid full price just like many Typhoon H owners. It is the way the business goes for UAV's.

    I agree about the sensors why the heck does this thing NOT have ground position sensors. Yuneec must think every one will always have GPS every where they go. So don't go into a large arena or in some thick forest that has a thick canopy blocking Satellites for GPS. Some day this feature will be put into their products like DJI has done. I'm not a big DJI fan mind you but when I lose GPS on my Yuneec stuff I'm forced to use the Phantom.

    Ground position sensors are very limited. Most are only 9 feet and after that it is GPS mode.

    Ok I thought they worked more to 9 meters which seems to be the height my Phantom is at in the arena and works great with no GPS and very strong exhaust fans moving the race bikes exhaust out. Even with that said that 9 feet is the distance, I'll take it because that is better then 0 feet and as time goes fwd those sensors will get better on the newer acft. I just have to agree at this price range the 520 should have every bell and whistle that Yuneec has to offer in it's arsenal.

    Bear in mind the 520 is not even remotely intended for the consumer drone crowd. It is designed to function at the Enterprise level, with tasks centered more on mapping, survey, and LEA purposes. Although it can be used as a camera rig it is not intended to be. The flight controller is largely Pixhawk/PX-4 based, requires study to understand, uses a much more sophisticated data logging program, and requires an intelligent operator, meaning well above the dumb monkey level most consumer systems are designed to satisfy. If you are accustomed to easy and simplicity the 520 is not for you. Those used to simple systems, and those that don't like to read instructions before using something for the first time, will induce unnecessary issues.

    Pat you are so correct in many ways with that statement. The jest is that the H520 is not for me but it's sad that they didn't keep us average monkeys in mind though. I like some of the newer features that they did with the H520 but as far as doing mapping goes well that is pretty job specific which is a good thing because not to many mfg are going to go after a certain market in mind and Yuneec did. How ever in the same breath left us average consumers on the side of the road wondering what the heck. I guess I'll have to wait another year to see what's next.

    Seriously, if someone is looking for a new Yuneec camera rig, and not another toy, take a look at the 920. It's designed around shooting video. The CGO-4 is pretty much a re-branded, mildly re-designed, 16 mpxl GH-4 with several levels of zoom. It's not a racehorse, it's made for making videos and taking pictures. Although not a 20mpxl camera, it's a true micro 4/3 and having the zoom means you have less to crop. Cropping a 20mpxl image to obtain a closer view can reduce it to a 16mpxl, or less, image real quick. You'll actually come out spending less for a 920 than for a 520 with camera as well.

    I took a long hard look at the 520, knowing I have no intentions of performing mapping work. The programs and accessory equipment necessary to do that right are quite expensive and I don't have a customer base looking for the service. The learning curve is pretty steep as well. Taking a step back I started looking at the 920 and found it already does pretty much all I need and want a system to do. It has waypoint capability, allows the import of maps to make use of way points, is brutally stable, tops out a tad over 30mph, has a range of ~1200-1500', which is plenty good enough for LOS ops, and you can buy after market batteries and install EC-3 connectors on them to allow use in the aircraft. The down side is that when Yuneec did away with the ST-24 and adapted the ST-16 to the system the 920 lost team mode when using the CGO-4. However, if you have a CGO-3 on an H Terrestrial Imaging has an adapter that permits use of the CGO-3, which may return team mode to the 920.

    It's a complicated system but less so than the 520. I've been in conversation with Terrestrial Imaging today to nail down some particulars before ordering. The one thing I've found is that you may want to remove the propeller quick mounts and go back to the old way using a couple screws to retain the props. A little more work, for some too inconvenient, but much safer and more reliable.

    Very true I have been looking at the 920 plus. Many nice features like team mode and the fact you can put the CGO3+ camera on it for a lighter load to get more air time. Once again it still has no ground sensors to hold position for the loss of GPS. The down side is the $ of the batteries to get the max flight time. I would love to see a hy-brid of the 480 to the 520, put on the new motors and some good ground sensors and call it a day. The real sense sys was something that I never did find a good use for or felt I could trust. It would be nice to see a good review in English on the 920 plus in action with the different payload cameras because I have yet to see a good video. All the video's I've seen are in a studio. I do have one question and that is does the CGO4 have audio like all the other CGO camera's?

    I wish I could answer the audio question but I don't know. Since the CGO-4 is for all intents and purposes a Panasonic GH4 camera I would suspect it does have audio capability. As for the addition of look down sensors, on a personal level I've never found a need for them. My larger copters have always been extremely stable with or without GPS functioning. For me it's only a matter of putting a little more thought into the hand flying when GPS takes a brief holiday. The 920 is a bit large for indoor flying unless the location is a massive warehouse or theater, places I'm not likely to be shooting in anyway. I don't have Real Sense on either of my H's and have never used the OA with them as well. In a year and a half I've had them I've only once been in a position where either would have served any purpose. I tend not to buy things I won't use all the time so I didn't get them.

    I really don't like a lot of reliance on technology. I can see where sensors could be helpful in tight spaces, since it's kind of difficult to judge distance from camera view, or far away by sight. Basically, just one more thing to go wrong.

    I remember when seat belts were optional equipment, had to pay extra, if you wanted them installed. But, you know, seat belts save lives, so they became required equipment, there were still deaths, and serious injuries, regardless of whether they were used or not, sometimes, they were the cause of the death or serious injuries, though we seldom hear about it, unless it happens to someone we know. Seat belts don't make you a better driver, and only help in some types of accidents. Some how, it became law, and drivers were required to wear them, and got plenty of tickets, if they didn't, but it was a secondary offense, until recently. You had to be speeding, or the old standard, 'your brake light is out'. Now days, everyone in the car has to be strapped in, it's a primary offense, $116 ticket (probably more, been a few years since last time I got popped). Wonderful invention, didn't stop accidents, deaths, or serious injuries. Not really that effective. since airbags are now mandatory equipment, which seem to be about as useless as well, not to mention cause injuries, couple of deaths, just from deployment. I've seen the abrasive rash on face and arms a few times, not serious, but probably a little painful, at first...

    I'd really hate to see a lot of these sensors becoming mandatory, since it would only drive the price up, the added weight and power drain, would shorten our flights. Really don't like the idea of fighting a computer for control of an aircraft. I'm sure there are plenty of people, who are hoping, waiting, for the day, when they just have to pick a point on a map, press a start button, and the drone is on it's way, no need for flight controls at all. For me, that day, would be a sad one, I just like to fly.

    You just referenced why so many like DJI. They don't know how to fly because they've never had to learn how to fly. Without auto take off and auto land they would have their aircraft at customer service more than in their hands. I knew an Inspire owner that had his aircraft rebuilt twice because of his inability to take off and land manually. He ended up always using the auto functions to overcome his deficiencies.

    Getting back to the original post, I believe we'll see the price of the 520 fall significantly fairly soon. IMO it's well over priced even when the E-90 is included in the package. My guess is <$3K is closer to the value.
