  • Trim efficiency

    hello everybody!

    I am fighting with my electric trim to get it more useful, I began but set it at the book setting i.e 27 downward, it was not set at this angle when I bought the Shadow. Not enough, I weight 92 kgs (you will say run a diet) its difficult for me.
    I add a piece of alu sheet, nearly doble the aera, very ugly!!!Now it works as far as the motor is running, during finale I have to pull on the stick not too much but I would like to set it also at this moment.
    Have you good ideas to sell!
    As I will use it as a monoplace, can I put a weight at the end of the boom and how heavy?
    Thanks for your good advices.

    I flew this morning, perfect weather, hand free most of the time

    Hi Philippe, it is not recommended to add weight to the end of the boom. Too much stress and could bend the boom on landing.

      Hi Philippe,
      I would agree that putting any weight in the boom is not good and may bend it,
      I cannot remember my trim settings as it was many years ago but I cannot trim to land and need pressure on the stick to flare.
      Just got back from my trip, thanks for the hospitality and bottle, it was emptied with enjoyment and I now need to learn to fly again fortunately the Shadow is in the air again after its holiday followed by clouds of smoke as the oil is burnt off.
      It is not back up to full strength yet and my landings are less than stylish but we will be back !!!

        Further thoughts on above
        Reduce the weight in the nose with less instruments , you don't need them in a Shadow , less weight on the nose leg ;-) and so on.
        Put a ribbed spacer between the prop and gearbox of about 30mm ( I have a drawing ) the bonus is you get more air to the prop.
        If that does not do the trick then move the engine back about 20mm and pivot the engine about the prop up to 5 degrees with a new engine plate.
        Prop needs to stay clear of the wing centre ribs in case of hard landing with full power (which deflects the engine into the wing because of the prop inertia) but the benefit is a removal of the torque effect on changes to the power setting so less drag.
        Overseas and SSDR only please .
