TECHING 160PCS Metal Remote Control Tank Robot Building Kits Bluetooth Speaker DM518

Très beau mais ne marche pas avec Android...

This is a real fun build. Easy to follow instructions. Well-constructed all metal parts. However, it needs improvement.
First. Though the instructions are in English, and they are very well written, they can be difficult to understand against the drawings. It would be better and much easier if the illustrations were in 3D color. Especially where parts need to be in a certain position, such as washers, and cover plates.
Second. The Bluetooth functionality needs to be improved. When the Robot is turned on, it does not auto-connect to Bluetooth. The user must completely exit out of the app, reenter and connect to the Robot. Operating the Robot will lose Bluetooth connection quickly, and when that happens, simply turning Off/On the Robot does not solve the problem. They App must be canceled and reentered for the user to reconnect.
Third: There is no response from the Robot that it has connected to Bluetooth, nor is there any indication it lost connection other than it not responding to controls. The app always indicates it's connected.
Fourth: The app design needs improvement. It's very difficult to control the Robot due to the independent L and R controls. It would be better if there was 1-lever for Forward, Back, Left & Right.
Fifth: While controlling the Robot while playing music it tends to stop the music in the middle and repeat.

The Robot is fun to build and it's a nice conversation piece. I've built 4 for the kids in the neighborhood, and they do like it a lot, but all had the same complaints.

Very enjoyable kit. Fairly clear instructions. Some of the lines could have been darker, but maybe at 74 it might be my eyes. All parts fit perfectly. It was very enjoyable y able build. And fun to play with.

I really enjoyed building this. So much so that I bought 3 kits and plan on doing more for kids in the neighborhood! Though the instructions are good, and the English translation is far better than I have ever experienced with kits from China, Japan and other countries; I do recommend that you view You Tube videos from those who have built them. It will assist you greatly following their step-by-step process. (I included a link to a video I highly recommend). The Instructions illustrations are drawings rather than 3D renditions, which makes assembly a little difficult. In many steps you will need a magnifying glass to figure out exactly what the instructions are trying to say. I would highly recommend that when you assemble the Right and Left mooters that you put a (R), (L) sticker on the wire near the connector respectively. This will be a huge benefit when attaching the wires to their respective ports on the board. Pay close attention to the Oil symbol. Its tiny and easily missed. I used 3-In-1 oil applied with a cotton tip. The MOST difficult part of the build is the head assembly. The large cable does not have a long lead making it near impossible to attach it to the board, AND at the same time attaching the servo. My recommendation is to attach the cable to the board first. Then insert the screw in the hole-holder of the servo in the FRONT. It will stay in place, so don't worry. Position the Circuit board over the servo and screw in the FRONT screw a tiny bit just enough to hold it. Then take the silver/gold screw post. Screw in the tiny screw at the top of the post, that will be used later to secure the plastic cover. This will help you to use your screwdriver wench to guide the screw-post into its position through the back of the servo securing it in place. You can then use pliers to hold the screw post as you remove the top screw. Once the servo is in place, secure the front screw and compete the assembly. Attaching the chains. They are VERY-slightly different sizes. Start with placing the chain on the BACK gears. If one is difficult to put into position, try another chain. You still have to maneuver it somewhat, but DO NOT force it! If it will not fit, try another! For sounds: I downloaded clips from Short Circuit, the Robot from Lost in Space, Ghostbusters theme and Star Wars. But that's just me.

Highly recommended kit so much fun making this model, Quality is very impressive, Instruction very easy to follow. The final product is good quality and easy to use overall I mark this model 9 out of 10.
