How to Upgrade Parts for a Traxxas Nitro Vee

Upgrade the Steering Servo

• 1

  Unscrew the servo horn from the steering servo, which is located closest to the vehicle's receiver. Slide the servo arm off the steering rod. Remove the four mounting screws that secure the servo, then pull the servo up and out, unplugging it from the first channel input on the receiver.

• 2

  Insert the new steering servo into the compartment, then secure it with the four fastener screws. Plug the servo into the first channel of the receiver, then turn on the receiver and transmitter.

• 3

  Adjust the steering trim by rotating the knob on the transmitter until the servo is centered. Press the servo horn onto the servo arm, then rotate the steering control on the transmitter. Test that the servo can rotate equal distances in both directions; if it does not, readjust the trim with the servo horn connected until it is perfectly centered.

• 4

  Tighten the mounting screw through the servo horn to secure it to the servo arm. Slip the steering rod back through the holes on the servo arm.

Upgrade the Propeller

• 5

  Loosen the grub-screw on the inner U-joint yolk. Slide the driveshaft out from the sheath, then insert the upgraded driveshaft that came with your kit. Push the shaft all the way in, then reattach the U-joint yolk, tightening the grub-screw to secure the connection.

• 6

  Loosen the propeller by unscrewing the fastener bolt. Slide the propeller off the drive shaft, then install the carbon racing propeller. Slide the carbon propeller up onto the driver shaft, then tighten the brass bullet nut to secure it.

• 7

  Spin the propeller manually to test that everything fits correctly, and that it is easily spun. Loosen the nut on the outdrive strut to adjust the trim angle. Slide the mechanism in closer to the boat to decrease the trim angle. This will compensate for the increased power output of the upgraded propeller.
