I broke the kit servo horn in my tc6 this last weekend. I've had a tc5 and another tc6 before and never broke the servo horn on either one.
I dug in my 8th scale stuff looking for a plastic servo horn that came with my RC8 which is more stout. I used a body reamer to open up the second hole, but I did not go right through the center of the hole because it would be too short. (the outer hole is way too long) As I reamed it, I progressed slowly with just the tip of the reamer and basically oblonged the hole and it is the exact size needed. After I was done, i cut the end off the servo horn and shaped it with a dremel.
I run aluminum horns on my rc8 and rc8t, so these were just sitting around. I figured i could buy extra tc6 servo horns but risk breaking more of them. Also, when i built the tc6 kit I followed the servo saver set-up of 0.5mm between the c-clip and bottom of the servo saver nut, so I didn't feel like backing off the nut was the solution as some of my fellow racers have said.
Definitely should never break an 8th scale servo horn on a TC.
The f servo horn is 25 spline and is used for futaba and savox.
