Phil69: I like dual servos , but the red nyrod works well. Use one of those ball & socket dual take off`s on servo, don`t anchor the push-rod too close to servo,as they have to move up & down some. Back when radios were made in U.S.A., most made a linear take off servo, this would be a good place for one, may-be someday,(big sigh goes here!) GOOD LUCK WITH YOUR CUB. big max 1935
