Gas engines - Does Prop alignment with stroke affect vibration?
Well, I've got a smooth running ZDZ-80 single on a H9 Cap with over 300 flights on it. Hitec 5945 servos with gears that are fine. I run either Menz or Mejzlik props. Engine is mounted on aluminum standoffs with a slightly reinforced motor box.
My buddy has a new 3W-150 twin that vibrates more than the ZDZ.....strange but true.
