The Tekno RC EB410 is highly tunable, but can be very aggressive depending on track conditions and tires used. To help with this, we
recommend that you are well informed about setting up your Steering End Points (EPA), Dual Rate (D/R), Exponential Curves, and Servo
Speed.
Start by setting your EPA such that the vehicle can reach ‘full lock’ while on the ground. Be careful not to go too far with this setting as it
may damage your servo. Drive the vehicle around the track. If you are turning into pipes or losing traction out of a corner, you probably
have too much overall steering throw. The simplest way to reduce this is with Dual Rate. Reducing Dual Rate will turn down both the left
and right side EPA proportionately without having to adjust the EPA settings independently. D/R is usually pre-assigned to one of the
trim buttons on most mid-to-high level radios.
The next setting is ‘Expo’ or ‘Curve’. Expo does not change your EPA or D/R, it simply turns the wheels less around center and ramps up
to the end points as you reach full lock on the steering wheel. We would suggest starting at -15%. If you’re vehicle still feels “twitchy”
around center, dial in more negative expo to continue smoothing everything out. If it starts to feel too numb around center, dial some
back out.
Another valuable and often overlooked radio adjustment is “Servo Speed”. Servo Speed allows you to slow the steering servo down from
the transmitter resulting in reduced twitchiness. We like to set this at around -40 to start. If you find that it’s too lazy, increase the servo
speed slightly and run a few more laps. Repeat as necessary until the steering response feels natural without delay.
After setting the servo speed you might find that you need to go back and adjust the expo setting. This is normal, it might take a few
adjustments of each to achieve the proper steering “feel” to suit your driving style and track conditions.
With these four settings, you should be able to make your vehicle consistent and easy to drive lap after lap assuming the rest of the setup
is close for your particular track. Of course there are many other factors and setup options to tune for more or less steering, but some-
times all your vehicle needs is a small radio adjustment to keep you headed in the right direction.
