Este set nos ha dejado sensaciones encontradas. Lo que prometía ser una genial idea de construir un coche de Lego Technic, que fuera teledirigido y además homenajear un personaje muy estimado, se ha quedado ensombrecido por una serie de pequeños fallos de diseño indignos de la marca y sobre todo de la gama. Se recibe en una caja mediana de 38 x 26 x 9 cm, algo grande para las pocas piezas del set, aunque luego sirve para guardar el coche a modo de garaje… HOMENAJE: Simula uno de los coches de rally utilizados en el famoso programa de televisión Top Gear de la BBC y pretende ser un recuerdo del enigmático piloto de pruebas “The Stig”. Incluso en este aspecto Lego no acierta, ya que la serie se dejó de emitir en ese formato allá por el año 2015 y este set pertenece al catálogo de las navidades del 2019, o sea, cuatro años de retraso y sin incluir por lo menos una mini-figura conmemorativa. El montaje es bastante rápido, aunque recomiendo ir repasando cada paso con detalle, ya que tiene piezas muy pequeñas, muchos encajes justos y un espacio reducido, lo que dificultará realizar correcciones posteriores. El coche montado mide 14,5 cm. de ancho, 27 cm. de largo y 10,5 cm. de altura en el alerón trasero. Una gran decepción que su ancho no fuera el estándar de sets como Lego Technic 42098 (www.amazon.es/review/R28Y5X34FC0ZQY/) o el Lego Technic 42093 (www.amazon.es/review/R3NZ6CTSDCS5Y3/) ni con otros coches de esa serie que tienen entre 12 y 13 cm. de ancho, todas las demás medidas coinciden… Evidentemente la calidad de cada pieza, los detalles del montaje y como se resuelve el diseño final están muy logrados, con una hoja de pegatinas que dan mucha personalidad al modelo. A destacar el innovador diferencial de transmisión trasero, muy similar a los sistemas reales de coches de carreras. La otra novedad muy destacable es el motor y la dirección motorizada, que crean un nuevo espacio de juego. Hay que bajar el aplicativo desde la plataforma de nuestro móvil y el emparejamiento vía BlueTooth es rápido y eficiente. Aquí debo mencionar que el botón de encendido queda dentro del coche entre los cables que van a los motores, otro pequeño fallo de diseño nunca visto en otros modelos de Lego. El manejo del coche teledirigido es fácil de aprender, no tiene una gran velocidad y la maniobra tiene unos tiempos de respuesta algo lentos, pero lo que para unos parece ser un gran fallo, personalmente creo que es irrelevante, dentro de la experiencia que supone para una niña o un niño, montar su propio coche teledirigido y que luego funcione desde el móvil… En resumidas cuentas, es un set divertido de montar, con grandes alicientes para explicar el funcionamiento de la mecánica de un coche y una gran experiencia de aprendizaje y superación, consiguiendo finalmente un producto acabado y funcional. En términos generales nos ha gustado este set, mi hija ha disfrutado con el montaje, pero ahora se divierte mucho intentando “adiestrarse” manejando el coche. A pesar de algunos fallos que nunca he visto con anterioridad y de un coste excesivo para el contenido, puede ser un gran regalo para familias aficionadas al motor y al mundo del montaje, aunque seguro que los entusiastas de Lego Techinic quedarán ligeramente desencantados … ¡Saludos a todas las familias!
