The printed parts are of very good quality. The little robot on Arduino is really a lot of fun. To dance well and to walk well, he needs a flat surface as possible. A little annoying, I find that there is very little space inside for the electronics and battery.

The frame is very, very stable. The parts are very precisely made and fit together perfectly. In addition you will find cables with an XT30 plug and various other parts as shown in the photo. I love the kit and I like to recommend it.

Is different then the handbag FrSky Taranis X7S. This affects both the dimensions, the interior layout and the material. Outside, the handbag FrSky Taranis X7 is made of a plastic that repels dirt and moisture well. I like it very well. Is practical and handy. So the transmitter is well protected.

This is the NiMH battery for the FrSky Taranis X7S. You can operate the transmitter with this battery for a very long time. I bought this battery to change. So I do not need to wait until the empty battery is charged....

The different FPV Racing Drone. Reminds me of the movie Avatar: D As you can see in the photos very nicely packed. ;) Many additional parts are not included. A battery tape, propeller, spare propeller, propeller screws set and so a black rubber thing. Reminiscent of a piece of bicycle tube. Can you touch a 2S or 3S battery and then the battery does not slip - I think. I have not tried it yet. User manual - no such thing is not there. The only information can be found on the shop page of Banggood.In addition, I bought a FrSky receiver. Receiver is not included in this version. The construction time is short. However, I had to remove the rear engine below to mount the propeller. Otherwise you can not get to the propeller screws. He does fly indoor very nice and as you can see on the video you can also fly it in the ground even in the smallest space. Indoor, the Dragonfly 110Y4 is really cool to fly. Outdoor I do not know yet. But as soon as I find time, I also test it outdoor. A base has the Dragonfly 110Y4 and that's not so good. And certainly one of the minuses. A second is that you can slightly bend the back arms. As a result, the propeller screws of the lower engine could touch the upper arm under great force. The FPV camera is really good. That relativizes the negative points then again.

Just great the part. In combination with a memory card better than a USB stick. Is smaller and more practical to transport.

Light and small - wonderful. It is also nice that the position of the pin itself can be determined. However, you should be able to solder and have appropriate soldering equipment to solder the pins on the board.

Very good quality. The transmitter offers a lot of settings and has really fun. The Semder is wonderful in the hand which makes a very accurate control possible. Very handy is also the transport bag, which is included. The only and biggest negative point is that there is no user manual, which could be described as such. That caused some frustration at the beginning.
