Review: Increíble! - Es un estupendo juguete, solo que, es más para adultos que para niños a mi opinión. El armado es algo diferente a otros juguetes de Lego por el diseño de las piezas, realmente hay pocos cubos y más piezas largas y pernos que ensamblar haciéndolo o sacándonos de lo que nos tiene acostumbrados lego. Sin duda alguna es un excelente regalo para quienes disfrutan de la ingeniería y la tecnología, a esto me refiero que es un juguete para adultos. El armado del motor es fácil, a manera de que el vehículo tenga tres velocidades, es fácil de controlar con la app y la conexión es buena, es preciso el movimiento y responde bien. Si bien no corre tan rápido como nos gustaría, el hecho de que tengas tres velocidades que tú mismo puedes cambiar y controlar lo hace único. Algo difícil de encontrar en otros modelos a control remoto. La calidad de los materiales es la que nos tiene acostumbrados la marca. Sin duda un bonito regalo para ese niño interior que aún vive en nosotros.
Review: Diversão garantida - O carro é ótimo, fácil de montar e o App para conduzir é sensacional, com várias interfaces para controlar. Lego nunca decepciona, material de ótima qualidade. A velocidade não é alta, mas está perfeito para o uso. Tem vídeos no yt onde pode ver en funcionamento. Recomendo para quem quer ser divertir montando e também dirigindo.

## Questions & Answers

**Q: is this car compatible with standard lego remote control & receiver, rather that using an app as the control?**
A: The old power functions is Infra Red based, while this is bluetooth based and has different connector ports. So, you would have to replace the blutooth hub with an older battery box, IR receiver, and at least two older power functions motors. Of of those motors would also optimally have to be a servo motor, which would facilitate returning the steering to center when the controller is in neutral. Doing this would mean so much work that it wouldn't look much like the original rally car when you were done. There may be a way to use the new Bluetooth power functions remote, but I don't know enough about how it operates to say that it would be fully compatible with the Rally car's steering configuration.

**Q: Can the Bluetooth remote 88010 be set to control the car directly, or does it need the official phone app to reset steering to neutral automatically?**
A: You need the LEGO app on your phone so can reset your controls

**Q: Is the steering proportional?**
A: I would like an answer to this question as well. Anyone? Is it all-the-way-left/all-the-way-right, or are there gradations in the turning so that turning the steering wheel a little only turns the wheels only a little?

**Q: I see four ports on the hub but can they all control a motor if needed, or are some ports only for sensors?**
A: Hi there, 
They can all control a motor if needed, for that you'd need 4 different motors.
