    Hello,Andrzej

    Thank you,
    Actually the oil cooler is too small.
    I have been testing the ground with a two times larger oil cooler and it is insuffiant.
    I will install a four times greater. I just bought

    Hello Andre


    I did some tests in static before mounting on the fuselage and I'm running regularly.
    The tests helped me choose the type of silent block, to develop the location of sensors taken oil temperature, oil pressure, fuel pressure sensor and the sensor engine hours.
    The propeller was obtained from "DUC HELICE" in France. I'm French.
    The gear was obtained from "TAKE OFF" in Germany. The reduction rate is 2.6 or 3.2 (I do not remember, I would have recherce on my invoice)
    The engine has an output of 80 hp (there is this model with a power of 100 hp)


    Excuzez my delay in responding.
