The build quality of the remote control, I would describe as normal. It consists mainly of plastic and is therefore also very easily, which is advantageous. In addition, were waived ornaments in the form of aluminum or the like. She slips out of your hand, neither immediately when hands are sweaty yet it feels like a foreign body. In my eyes, the size is only slightly oversized. 10% less could have been more here. Should drop they'd better not, I am afraid that then cause irreparable damage. The biggest shortcoming of the processing is that pickled 1.2V NiMH batteries are not charged via the charging socket. However, I recommend anyway normal batteries with 1.5V. Experience shows that the remote control then works much more reliably and the reach is increased again.
With the reliability and capacity, I am very satisfied. Initially I had some problems what comes to the Bindig. After extensive troubleshooting the binding is only error-free when especially the battery still provides enough power in the vehicle. In addition, I have found that the binding with 1.5V batteries work better and faster. I'm simply assume that 8x 1.2V are too little for the remote control. Since I use 1.5V batteries instead of batteries I have no more problems with the binding. I turn on remote control and the vehicle, shall be exercised within two or three seconds the connection. Also in the second receiver this works without any problems.
The range I would appreciate felt at 150-200m. However, this is also a bit on the environment. As it was very windy I sat down in the car and controlled. Through glass windows the wireless range is pressed on 50m. In environments with a lot of iron (parked car) can also lead to problems with the connection. For this purpose, but you have to say also that it should be clear from the outset.
Slightly more feature I would have liked from the trim levers. The trimming function is useful and convenient, but does not go far enough in terms of their attitude. Since it is often more helpful again to build the steering and to bring the lever one tooth again.
Overall, despite a few shortcomings a very good remote for the hobby riders or beginners! Unbeatable for this price!
