Customer Review

I have revised this 5-star review after 8 weeks. The assessment of Copters is still very positive, but limited his "Chinese" quality the fun considerably, so I can not give buy rating.

Summary:
the U829A is an absolute fun machine. It flies in comparison to other model aircraft super simple, very stable flight, you can fly in wind, survives even violent crashes, and is therefore particularly suitable for beginners. But he can also be configured so that even more experienced "fliers" have great fun with it. Motors and rotors are dimensioned so that the copter theoretical additional load such as can carry a Mobius camera. Without the context of the copter is very lightweight and portable, and so can be taken on the backpack also eg.

Update: after two months I can identify two significant weaknesses: For me the wrong power supply was provided, which was specified for 10V instead of 12V. Accordingly, the charging of the batteries did not work really well. The engines are a very weak point. The stop a few hours, I have now replaced all motors once, one of the new engines also already begins again zicken. The life of the engines is very different, which suggests serious problems in the production close. Another indication is the very amateurish soldering of contacts and significant differences in performance of different engines, the well compensates the electronics to happiness. ... For these significant shortcomings, there are two star deduction.

In Detail:

Handling:
The remote control can be operated with 3 or 4 channels. But I recommend clear four channels, the meaning behind the 3 channels reveals itself to me not because then the "Aileron" is missing. You can set 3 sensitivities that are marked as "speed", but primarily probably the response ("gain") change. The abbreviations used ("L", "M", "H") also point rather to a "gain controll". To "L", the control for very delicate maneuver is suitable, "M" is the all-round setting and always active at power-on "H" of the copter is very responsive to steering inputs, making it especially outdoors very well to navigate. "H" should not be used as a beginner first time, because as a beginner, almost everyone tends to overcompensate the movements of the copter, which then quickly leads that you lose control.

The remote control does not look cheap, but not really high quality. The control horns are a bit cheap and should be better treated with sensitivity. You own on the upper edge fine serrations, and a rough edge, therefore are very handy. The mechanism runs astonishingly accurate, the electronic transfers sufficiently sensitive. I'll be very good overall with the control handle, unlike other controllers in this price range.

The controller has, inter alia, an indication of the link quality. This display is also an explanation for the observed by some users related disorders: from about 50 meters, I could see that the signal suddenly breaks, and then a few seconds needs to be fully back. The electronics of a 100 Euro Copters can not reach the quality of a 400 Euro Graupner remote control stop. In connection problems I could observe two phenomena: 1. Sometimes a brief revving the engines (not good), 2. with complete loss of connection, the motors are switched off, which of course has a crash. That must be so, because an uncontrollable Copter is definitely dangerous.

For me, the transmitter antenna is not the way in which plastic Oppel at the front, it is in the housing glued diagonally. That is unkind, one would have to unscrew the unit to see the exact location. For me it is about rotated 45 ° to the antenna dummy. That's important to know, because for best transmission power of the antenna length must be directed towards the copter, not the tip. This can have a significant impact.

Overall, the device is good-natured and easy to control. The range corresponds to the oft-quoted 100m, which in adverse conditions possibly also can occur even from 50m problems.

Wind speed:
The copter comes very well with wind handle, you can fly even at an appreciable wind, it's great fun and is a special challenge to fly in turbulent air. Unlike many other simple Coptern you can let it fly even up to a few km / h headwind.

In the house:
for the house of the copter is only suitable time, he's just too big. In large rooms, no problem, but for the small city apartment rather then the U818 is suitable. In the house let the frame off when one is fond of its establishment, the rotors have the right force. The greatest fun is definitely with the U829 outdoors.

Stability:
The frame consists of EP foam, ie a common model for the flight material. It is mounted on an inner plastic frame, which additionally gives the material stability. I guess a flight at maximum speed in a wall would probably damage the frame. For me he has already survived but countless crashes without any damage. Addendum: I have the frame away soon, because without flying the copter significantly more agile. The engines seem the weakest link. Two I have already exchanged. The arms are super stable, they have been even a "ground contact" at full speed from a great height survived (descent from about 30m). One foot got a crack at the opportunity. A propeller had to believe in it, as the wind tossed the copter at high speed against a wall. The propeller was bent back, but now, of course, a predetermined breaking point which could be very dangerous. Therefore better exchanged. Apropos: as for all model aircraft is in Germany a liability apply if you want to use it outdoors.

Flight time:
After a few flights the battery reaches its full capacity, with staked camera and without light can be times for 15 minutes with full lighting and the camera rather 5-8 minutes. I immediately ordered me to two spare batteries, then you can extend the fun considerably. Then pay attention to the temperature of the motors, which can be very hot, because it is allowed to start trying out cool a few minutes.

Camera:
the original camera is ok great for the price for learning and performing. If you want to make really good videos, the copter easily carries a Mobius or even a Gopro. Meanwhile, there is a version with HD camera that costs about twice as the single camera. Reviews to the new camera I have not found. Would also be interesting if that can be like all the other parts of Copters purchased separately.

Load capacity:
The manufacturer offers payload only the camera in a simple or HD resolution. The copter is strong enough to carry additional payload, which is only possible with a little tinkering. On the Internet there to videos. I have a test basis the included camera is replaced by a Mobius what mitmachte the copter without grumbling. The flight time was thus 10 minutes without frame, so clearly the tolerable range. But such tinkering should only make experienced modeller.

Fun:
The U829 brings the maximum fun factor. The whole family is thrilled and the copter is currently in daily "use".

Quality: the one can always judge only after a time, and since the fall U829A with me by resoundingly! Here the updates:

Update: after some time began the charger to zicken, eventually it did not at all. It was not until I discovered an incredible sloppiness: the charger has a 12V input supplied, will be a first power supply --- 10 V output. Although this is better than 14V, still a brazen sloppiness (so does not happen by accident, the 10V is a very uncommon voltage). Therefore, I have written down the unit by two points, because such a thing should not happen, that's it! With a 12V power supply, the charger is working again. Better to use probably a higher quality balancer, if available. It has unfortunately been confirmed once again that in China the quality of print "High Quality" practically a guarantee of sloppiness and inferiority is.

Second Addendum: A test with a high-quality balancer shows that the supplied Balancer overcharges the battery, to 8,35V. This is likely to affect the service life considerably. The devaluation of the charger is already inside, but meanwhile a motor is already blown. You can not use intensively this quadricopter that he does not hold out. Therefore, I prefer from another star, and change the title.

After 4 weeks I have mothballed the part, because I'm tired of constantly nachzukaufen engines and now for considerably more money (300 Euro + Remote Control) which bought me reasonable, the infinite fun and easy every purpose.

Conclusion: To get a taste there are better quadricopter not suitable for intensive use thanks to the miserable engines.
