Check that the rubber shocks, especially one of them, hasn't gone soft Sent from Yahoo Mail on Android On Tue., 22 Sep. 2020 at 3:36 pm, Győző Horváth<[email protected]> wrote: Hi Ian, Thank you for your answer.I have the later version tailweel with rubber shocks.Unfortunately I experienced the shimmy with different pressure in tyre between 2,5-3,1.

Do you have the rubber shocks in tailwheel on later versions or is it fixed without any rubber springing?. If former version I add a few washers to make the tail wheel more vertical. Go to google and tail wheel shimmy and you will see pawnee scott tail wheel and poor angle and better set up.

This can lead to shimmy. regardsRob Rob Thompson0429 493 828 On Mon, Sep 21, 2020 at 6:01 PM Győző Horváth <[email protected]> wrote: Hi Rob, Thanks for your advice.We checked the shaft.There is a tiny movement of the shaft.Is there any acceptable limit (if yes, how it should be measured) or no movement is required? BRGyozo 2020. szept. 20. dátummal, 8:45 időpontban Rob Thompson <[email protected]> írta: If your cables are properly adjusted, it is likely that the bearings on the tailwheel shaft are a bit worn or the nut on the top of the shaft is not tight enough. Lift up the tail and check to see if there is any movement up and down or side to side.A small amount of forward pressure on the stick stops the shimmy. regardsRob Rob Thompson0429 493 828 On Sun, Sep 20, 2020 at 3:42 PM Győző Horváth <[email protected]> wrote: Hi, I often experience shimmy of the rear gear when I operate on concrete. It is linked to a certain speed during acceleration for take off and after landing as well. Springs and cables seem to be OK. Tyre is not worn. Pressure is OK. It happens on international airports with good quality asphalt as well. Does anybody of you have such experience? Why is it not allways, just often? How can I avoid it? How dangeruos it is to the glassfiber material of the tail.
