Hot Racing Traxxas TRX-4 Aluminum Control Link Servo Arm (Blue)
I ordered the 3 of these needed to replace the 3 stock parts when i got my trx4. I only ran the truck for a few minutes before tearing it apart and replacing nearly everything with better aluminum and brass parts, but nearly a year later these servo horns have never given me one issue. I did have to replace one of the tiny servos these mount to, but that had nothing to do with these, it was simply a cheap servo issue. I tried to upgrade all 3 servos at the time but didnt have much luck finding servos of the same size that were any better. Probably small helicopter servos? I did have to adjust the end points after installing them as they had a slightly different throw than the stockers, so im not sure how that would work with the stock radio system. It was simple for me though as i use a Futaba 7px and their 8 channel reciever. All 7 channels are used too! High/low shifting, front and rear lockers, full lighting kit and the winch i added.
