A wonderful game! I have tried a lot of radio-controlled toys and was mostly disappointed. The 27/40 MHz transmitter, usually had a much too short range, so you had to constantly run after. Quite different in this Truggy 2.4 GHz.Technik. 30 yd range is no problem at all and even with two new walls with reinforcement, there is a secure wireless connection. (But who already travels through two walls?) With one battery charge you depending on the driving handle, about 10 minutes driving fun. The car battery is a 140 mAh LiPo and can be charged via a USB socket on a computer, or via the transmitter. The steering works proportional and can be perfectly trimmed on the transmitter. The maximum travel speed can be selected in 5 stages and is then infinitely variable. I went only to Stage 2, then my part is simply too fast! 5 stars I forgive compared to the 27/40 MHz channels. Those who are familiar with the 2.4GHz technology, know that the recipient must always be bound to the transmitter, which in turn has the advantage that multiple models can drive completely independent. To bind the first Truggy must be switched on, only then the transmitter. With high-quality remote controls that's exactly the other way around (the cost then but also real money). After that you should make a function test. If now, for example, as in my case, the model does not run backwards, the white trim pot must be changed on the transmitter until in both directions, a uniform rate is achieved. The transmitter must always back off and turned on. A disadvantage of the vehicle, which can be seen the "Bind-LED" on the recipients of outside bad, is expressly pointed only through a small hole in the housing and why a removable steering servo, remains a mystery, because the servo is a special servo and not compatible with others. The manual is very brief and assumes certain Kenntisse. Conclusion: Good technique for little money.
