TRAXXAS HIGH TORQUE 330 SERVO

FEATURES

Traxxas’s High Torque 330 servo has a lot of bells and whistles packed into that case and it’s not too often that we see something like this from a vehicle manufacture. They’re direct replacements for all of Traxxas’ vehicles but Traxxas recommends that you pair it with their external BEC when installing it into the TRX-4 equipped with a XL-5HV speed control to get the optimum performance out of it. The center section features an aluminum piece that’s blue anodized for this specific servo; it looks great and helps dissipate heat. Like all of Traxxas’ other electronics, the 330 servo is well sealed making it waterproof. Inside the case are metal gears, dual ball bearings and a coreless motor.

TESTING

For testing I decided to drop two 330 servos in a Traxxas E-revo VXL to see what they could do. Of course, since they’re Traxxas servos, I had no issues at all with fitting them in the E-revo’s chassis and the servo arms went on with no issues. Traxxas recommends only using one of these servo in the E-revo because it produces over 2.5 times more power than the ones that it will be replacing. Using one saves weight and it has less possible strain because it doesn’t have to fight the power of another servo. The downside to only using one is that it only gives the steering a small 80 oz. in. bump when compared to the stock setup. I started by connecting only one servo before heading out for a spin and I did notice a slight improvement in performance and I didn’t feel that the servo was being overworked. I eventually connected the second servo and went back out for another ride and this time the combined 660 oz. in. of torque was very noticeable. It made the E-revo feel more like a high performance race vehicle when it comes to steering performance. The servos worked flawlessly throughout testing.
