BASIC TUNING ADJUSTMENTS
DUAL SERVO STEERING SYSTEM
E-Revo uses dual-servo steering and a single heavy-duty servo
saver for powerful, responsive steering. To prevent unnecessary
receiver battery drain, it is important to make sure that the servos
are “at rest” when the steering is at neutral. If one servo is out of
adjustment, then both servos will work against each other, fighting
to find center.
Adjusting The Steering System
1. Remove the servo horns and steering links from the servos.
Disconnect the steering links from the servo saver.
2. Adjust both steering links
to be the exact same length
(31.7mm - use “Steering Link
Length Template” to set
length).
3. Switch on the power to the
receiver and the transmitter.
4. Adjust the steering trim on
the transmitter to the neutral “0” position.
5. Connect one end of a steering link to the steering
servo saver arm and the other end to the servo horn.
6. Position the steering servo saver arm
perpendicular to the centerline of the vehicle.
7. While holding the steering
servo saver arm in the position
mentioned in Step 6, install the
servo horn onto the servo such
that the steering link is parallel
with the centerline of the vehicle.
This will automatically set the
servo horn at the 7-degree offset
shown in the illustration.
8. Install the second servo horn on
the other side following the same
procedure.
If necessary, fine-tune the length of the second steering link to
eliminate any load on the steering system in the neutral position.
If you are using aftermarket servos, it is important to use servo
horns designed for E-Revo. Optional steering servo horns are sold
separately for use with non-Traxxas servos.
Servo Saver Tuning
An optional stiffer spring is available for the servo saver when
using servos with metal gear sets (see parts list for details). Do not
use this spring with standard Traxxas high-torque servos.
Maximum Travel Steering (optional)
The stock E-Revo steering system provides
a good balance between steering sensitivity
and turning radius. E-Revo includes an
optional maximum travel steering stop
that can be installed for maximum steering
throw, which may be desired in racing
applications. This provides sharper turning
at low speeds, but also makes the steering
more sensitive at high speeds.
To increase the steering
throw, replace the stock
steering stop with the
included maximum travel
steering stop on the model.
This part has modified
steering stops to allow
increased travel. Once
installed, reposition the
steering links to the outer
holes on both steering servo
horns. Refer to the exploded
views included with the
model to assist installation.
