    Hola:
    El fan viene en el interior de una caja de EPP con los conectores soldados y termo retráctil.
    El conjunto del fan viene en dos piezas, fan y el borde de admisión.
    Hemos preparado unas cuadernas en unos retales de placa de circuito impreso para simular el sistema de sujeción que haremos en el avión y poderlo sujetar al banco de empuje.
    La cuaderna ha de quedar a 18 mm de la parte trasera del fan, marcamos estos 18 mm para el posicionamiento en la cuaderna y nosotros hemos añadido un poco más de cinta como observáis en la foto.
    Una vez sujeto el motor a la cuaderna y comprobando su fijación lo montamos en el banco de empuje.
    Hemos realizado dos ensayos, un ensayo con batería cargada de 3S y 1500 mA/h 40C y otro con batería cargada de 4S y 1600 mA/h 50C, empleamos un variador de 60 A y el vatímetro y banco de la foto. Siendo purista posiblemente el empuje no sea totalmente real pero para tener un orden de magnitud creemos que es más que suficiente.
    PRIMER ENSAYO: 3S
    El empuje con la batería de 3S es de 546 g con un consumo de 25.7 A y 275.5W en el momento de realizar la foto, pasados unos 3 segundos.
    Foto 23 095951
    Teniendo en cuanta esta medición, tenemos una relación de empuje/peso de 7.28.
    En el momento del arranque se oye el roce del rotor en el estator pero luego desaparece, pero no sabemos cual puede ser su influencia.
    Aunque curiosamente no tenemos ninguna vibración.
    SEGUNDO ENSAYO: 4S
    El empuje con la batería de 4S es de 903 g con un consumo de 42.4 A y 630.4W en el momento de realizar la foto, pasados unos 5 o 6 segundos.
    Foto 23 100139
    Teniendo en cuanta esta medición, tenemos una relación de empuje/peso de 12.04.
    En el momento del arranque se sigue oyendo el roce del rotor en el estator pero luego desaparece.
    Aun así no tenemos ninguna vibración.

    Bueno esta es la información que os podemos ofrecer con los medios que contamos.

    Gracias, un saludo.

      Q: Can you tell me if it's possible to configure it CW or CCW ? I need to 2 but they need to be CW and CCW.
      A:
      These are only CCW. You would need to swap the fan blades for CW and also reverse the motor by swapping any 2 of the 3 motor cables.

      Q: How does one mount these?
      A:
      Using inexpensive 5mm foamboard from the dollar store, you build a foam airframe. For example use google ti find the the F86 Sabre 50mm on the flitetest site, with free plans and videos. You use a hot glue gun to attach the outer shell of the fan inside the fuselage. Easy!

      Q: Since I need four engines, is it possible for this unit to have a CCW and CW motor? I've designed an engine nacelle with thrust reverser mod it doesn't mean reversing the rotation of the motor using a reverse compatible Electronic Speed Control, but it has Blocker Doors and Cascade Vanes based on the real-life engine nacelles and The Good news is, it fits this Electric Ducted Fan Unit.

      Q: if i use the recommended battery for the 5400kv, how long would the flight time be?
      A:
      Itdepends on the ammount of thrust you want it to provide, number of motors and also on the ESC. But my batteries which are a bit higher than the recommened makes one of these motors run at max during 8 minutes.

      Q: Olá vc teria a bateria pra rodar esse motor com o controlador? esse motor daria pra colocar em uma fonte?
      A:
      Motores brushless não podem ser ligados diretamente numa fonte, você precisa de um ESC e também de um controlador 'de aceleração' (dimer). Quanto a bateria, infelizmente as leis brasileiras impedem a entrada de baterias LiPo (recomendadas para estes motores), por esta razão as lojas internacionais não enviam baterias para o Brasil, mas aqui no Brasil você consegue compra-las em lojas especializadas ou no Mercado Livre.
