Pete DeVries Thursday, Aug 1 2019 (about 6 years ago) Hot Racing Aluminum Control Link Servo Arm for Traxxas TRX-4 (Blue) I ordered the 3 of these needed to replace the 3 stock parts when i got my TRX4 Defender in September 2018. 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 as it failed which is somewhat common it seems, but that had nothing to do with these, it’s simply a cheap Traxxas 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. I did have to adjust the end points after installing them as they had a slightly different throw than the stocker servo horns, but once I got them set they havent needed any further adjusting. Good looking upgrade and would buy again if I build another TRX4. 5 customers found this review helpful. Tae Kim Verified Owner Saturday, Jan 14 2023 (about 2 years ago) Hot Racing Aluminum Control Link Servo Arm for Traxxas TRX-4 (Blue) Bought three of these and paired them with my new sets of EcoPower 640T to replace the stock servos on my TRX-4. They fit perfectly and the built quality is miles ahead of the stock plastic ones. Just put your stock “servo saver” springs back onto these and you’re ready to go.
This is cheap insurance in terms of longevity and strength. View all reviews
