Is it good or is stainless steel better?

CF

In my opinion CF is good because it is usually made of arrow shaft and is straight doesn't get affected by temperature where as Aluminum ones may not be that straight and need more support bearings . They are known to be cheaper though

All though I like the CF rod (it's just more straight to begin with, less vibrations), it does tend to more fragile compared to the stainless ones.

I busted 2 cf rods on light tailrotor-mother earth touches. Although very stiff (bending force) it does not like twisting and just splits up to the middle bearing. Result is a tail that is not steadily delivering power but in gusts (very short ones off course). This is because kinetic energy(twisting energy) is build up in the tailrod like a rubberband.

Still I would always go for CF as the 2 stainless ones were already bent out of the box

Greetz,

Depends on what type of tube you use.

Pultrated Carbon Rod is made by extruding carbon thread, just like extruded aluminum. Length wise stiffness is excellent but it's very fragile under flexing and torsional loads. It's very cheap which is why most manufactures use it for tail drives. They just make it thicker to make it more durable.

Wraped Carbon Fiber Tube, which is made by wraping pre preg carbon fiber fabric around a manderl then cured under heat and a vacum. It is far supiior to pultraded, but much more expensive.

Never go full retard!
