I have a Trex 500 ESP (Flybarred, GP780). This model comes with a metal rudder control rod and I have wondered if this contributes to the little bit of tail movement this heli has (very minor wagging). I therefore decided to convert from a metal rudder control rod to a carbon fibre rod. I purchased a Trex 500 carbon fibre rudder control rod, made for a later model and adapted it (shortened it) for my heli. Effectively, I still am still using the original metal rudder control rod but it is now runs through a hollow carbon fibre rod with one tail control guide. The end result is a straight control rod which moves smoothly, however it has turned out to be a bad modification. The heli now has poor tail control. I can easily conclude it is the new control rod set up although I don't understand the logic of it. I had at the same time replaced the front tail drive assembly due to a small accident (with the correct parts for this heli), which also involved removing the GP780 to effect the repair.
Do you think this is a control rod issue or have I upset the GP780 somehow ?
I can of course go back to the original rudder control set up.
Many thanks
