Plastic tubing of diameter 2/0,9 mm and length 1,5 meter can be used as pushrod outer tubing. The inner part is piano wire 0,8 mm.
The pushrod end to be attached to the servo arm or/and movable surface horn can be made by different methods:
- Z- bend
- L- bend
- Ending with "fork"
- Cylindrical ending
As the alternative, the piano wire can be replaced with carbon rod 0,8 mm which is much lighter.
