In step 5, I have to release the servo horn screw in order to pull the horn off the servo. This screw is very, very fixed, I cannot release it. I guess I have to fix the horn with one hand (even tried a gripper to fix it) and turn the screw anti-clockwise. Right?
I tried with another servo in the kit, the same task was quite easy there. Now, I do not want to break the servo or the horn by applying too much force. What could I do, are there some special hints/tools/… how this could be done?
Use a high quality screw driver. Make sure it fits very well, and is not loose or sloppy. You can hold the nylon round servo horn with whatever will hold it best. It will not be used and it’s ok if it gets damaged. You can also install one of the brackets onto the round servo horn for more to hold onto. Although I have never had one so tight it couldn’t be removed, but they can be difficult from time to time. You want to use a short jerking motion to snap it free.
One can latch a pair of vice grip pliers on the handle of the screw driver at 90 deg to the screwdriver shaft to make a half t-handle setup. This allows applying the pressue on the screwdriver to keep it seated along with the needed controlled high torque to break the screw free. Along with the appropriate screwdriver size that fits the screw slots, the best way I’ve found to break a screw free without damaging the screw slots.
Thanks for the hints… I combined all of them and then it worked! I guess the most helpful thing was to increase the lever by connecting a bracket to the horn. I also bought a different screwdriver which fit 100 percent.
