Shock Filling Instructions

For both front and rear shocks

Step 1. Start by drilling out the emulsion hole. Use a 1/16th (or 1.6mm) drill bit to drill all the way through and clear any ﬂashing created by this. Insert the four larger o-rings into the emulsion caps and set aside. Install the small o-rings onto the small emulsion screws by placing the o-rings on a pit mat or towel and pressing the screws into the o-rings (add 1 small drop of oil onto the seal to help make the screw slide in easier).

Step 2. Fill shock with oil all the way to the top and pump the shock shaft up and down 3-5 times.

Step 3. Screw on the cap all the way tight (shock tool TKR1115 is helpful for holding the shock body).

Be careful to not cross-thread the caps. Start by turning in the oposite direction before tightening.

Step 4. With the shock at about a 45° angle, push and hold the shock shaft to the top of the stroke and insert the prepared emulsion screw/seal. Oil should leak out during this process. If it does not, add more oil. Tighten the screw until snug (do not over-tighten). Wipe o excess oil before moving on to step 5.

Step 5. Pump the shock shaft up and down about 20 times vigorously. This emulsiﬁes the oil.

Step 6. With the shock shaft fully extended, remove the emulsion screw from the cap to do the ﬁnal bleed.

Step 7. With the shock at about a 45° angle, push and hold the shock shaft to the top and insert the

prepared emulsion screw/seal again. Oil will leak out during this process. Finish by tightening the screw until snug (do not over-tighten).

We've found it's easiest to complete steps 1 & 2 on each shock before moving on to step 3.

By the time you've ﬁnished step 2 on the last shock, the ﬁrst one will be ready for step 3.

Body/Tires

The purpose of making adjustments is to make the car go faster around the track, or to make it more controllable, or both if possible. A car that's easier to drive should produce lower, more consistent lap times. It will also inspire more conﬁdence in the driver, which is always good when nerves start getting the best of you.

Before you start thinking about changing your car's setup, consider these two things: First, is the car in perfect working order? Be sure that all of the suspension components operate freely without excessive play, and that the car isn't tweaked. Binding and worn out parts will result in poor performance and inconsistent handling. Second, always consider tires before making other adjustments. Time spent trying to get the vehicle to work with the wrong tires mounted will be wasted time. Without the right tires, even a great setup won’t be a winning setup.

Droop

Ride height is the distance from the bottom of the chassis to the running surface. Ride height should only be checked and adjusted with your vehicle ready to run (i.e. with battery installed/body on). Ride height is the ﬁrst adjustment to be made and should be set with a ride height measurement tool. Measurements should be taken from the ﬂat parts of the chassis, front and rear. Be sure to measure the front ride height at a point before the kick up in the chassis starts. To measure ride height, ﬁrst make sure the suspension is completely free, then simultaneously compress the front and rear all the way down and let the vehicle settle. Take your measurement from that position. Use the shock spring adjustment collars to raise or lower the ride height to your desired setting. 27mm front and rear is a good starting point.

Think of bump steer as active toe when the suspension compresses or rebounds. To adjust bump steer you have to change the angle of the steering link. This is accomplished by adding or removing washers under the ball stud on the steering spindles. Anytime you change camber link locations, front arm pills, front arm spacers, or Ackermann you will need to check and possibly adjust your bumpsteer. It's best to start with zero bumpsteer or slight bump out.

Think of Ackermann as active toe when the steering moves from left to right. More ackermann eect makes more toe out at full turn and produces more steering o-power. Less ackermann eect makes less toe out at full turn and produces more steering on-power. A good starting point is 0 washers behind the ball stud.

Ride Height

MEASUREMENT

Camber

Static camber aects the car’s side to side traction. More negative camber front and rear quickens rotation in corners. Less negative camber will make the vehicle easier to drive but you may give up some responsiveness (i.e. steering). To set your static camber have your vehicle at ride height (see above) and adjust the camber links until desired angle is achieved. Please note that a large adjustment of front camber will aect front toe and you may have to readjust the toe and

then re-check front camber again. A good starting measurement for camber is 1-2 degrees in

the front and 1.5-2.5 degrees in the rear.

Droop is the measured amount of down travel in the suspension. It is measured from the shock mounting points while the vehicle is up on a stand allowing the arms to hang freely and is adjusted by turning the droop screw located in the suspension arms front/rear. This screw limits the suspension travel by providing a stopping point against the chassis. Left and right sides should always be equal, however the front and rear of the vehicle can have dierent values. Droop aects all aspects of chassis performance, including braking, acceleration, jumping, traction, and bump handling. A good starting droop measurement is 88mm front, and 108mm rear.

Front toe is used to describe the angle in which the front wheels point when looking down at them from the top of a vehicle. You will always use some amount of toe out. Toe-out will aect how your vehicle enters and exits corners. More toe out will result in more o-power steering and less on-power steering and less toe out will have the opposite results. To set your front toe, have your vehicle at ride height (see above) and adjust the steering links until desired angle is achieved. Please note that a large adjustment of front toe will aect front camber and you may have to readjust the camber and then re-check front toe again. A good starting point is approximately 0.5-1 degree of toe out per side.

Changes to wheelbase can aect the overall handling of your vehicle, since it adjusts the distribution of weight on the wheels as well as the angle of the driveshafts. Shortening the wheelbase at the rear will give you more steering into a turn and o power, less steering out of a turn and on power. Lengthening the wheelbase at the rear will yield the opposite results.

Shortening the wheelbase in the front will land jumps a little better and lengthening it will be better through small bumps. In general a longer wheelbase is better on open and/or bumpy tracks and a shorter wheelbase is better on tighter technical tracks.

This chart shows the recommended starting ratios for the common motor types. Please consult the motor/esc manufacturers recommended settings to ensure you start with the best ﬁnal drive ratio (FDR) for your equipment. When setting your mesh you want have it set as tight as possible, without any binding. Tekno RC is not responsible for damage done to your electronic equipment or gears due to improper gearing or mesh.

* For bearing maintenance, please refer to page 28.

Softer springs will increase traction through the turns by allowing more roll, slow down the responsiveness of the vehicle, and can be better in the bumps. Stier springs will increase corner speed if traction is available and will also tend to jump and land better. Once you ﬁnd a set of springs you like you will typically only change them for tracks with dramatically dierent conditions.

Sway bars are used to adjust a vehicle's lateral grip by resisting chassis roll. A thicker bar decreases roll more than a thinner bar will. More roll means more grip and less roll means less grip. The front sway bar aects mainly o-power steering at corner entry. The rear sway bar aects mainly on-power steering and stability in mid-corner and at corner exit.

Pistons with smaller holes work well for smoother tracks with large jumps

and pistons with larger holes work well for rougher tracks with less jumps. Smaller hole pistons will typically use thinner oil than larger hole pistons. Shock oil is also aected by the ambient temperature so a change in viscosity might be necessary with a change of 5°C or ~10°F.

Front: Changing front di oil aects overall steering response. Thinner can increase o-power steering but

the vehicle may be twitchy and harder to drive. Thicker can increase on power steering and stability. We recommend 30k in the front di.

Center: Changing center di oil aects the front-to-rear drive balance. Thicker will reduce o-power

steering and on-power rear traction but increases on-power steering and acceleration if traction is available. Thinner will increase o-power steering and on-power rear traction but reduce on-power steering and acceleration. We recommend 30k in the center di.

Rear: Thinner rear di oil increases o-power steering and reduces traction into a corner. It also reduces

on-power steering and increases traction out of a corner. Going too thin will make your vehicle inconsistent, however. Thicker rear oil will have opposite eects, and once again, going too thick will make the vehicle inconsistent. We recommend 5k to 10k in the rear di.

Setup Information

(continued)

The Tekno RC ET410 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 sometimes all your vehicle needs is a small radio adjustment to keep you headed in the right direction.

Notes:

Bearing Maintenance:

Performing regular maintenance will greatly improve your on track consistency and also extend the life of your vehicle. Going through critical areas of the vehicle regularly will also allow you to ﬁnd possible issues before they become a problem that may cost you a race. Follow the guidelines below for maximum performance.

Bearings should always be smooth and free in order to preform their function. We recommend inspecting and cleaning each bearing on a regular basis. It will be necessary to break down parts of the vehicle in order to inspect them properly. The procedures below should be done every couple of weeks or prior to an important race.

1. Inspect the outer seals for any visible damage and check the rolling resistance of each bearing.

2. If any bearing does not spin freely, then take the following steps to clean them.

3. Spray the bearing with motor spray and spin it again to remove any debris trapped inside. Repeat if necessary. If the bearing does not start to spin freely after cleaning, then they may need to be replaced.

4. Allow the clean bearing to dry or blow into the bearing with compressed air to speed up the drying process.

5. Oil each bearing with a proper bearing lubricant. One or two drops is enough.

Shock Maintenance:

When comparing the left and right shocks of the front end, they should feel identical. Same goes for the rears. The procedures below should be done every race day to make sure they are leak free and operating correctly.

1. After removing the shocks from the vehicle, remove the springs and inspect each shock for visible leaks (build up of debris at the bottom of the shock shaft or visible oil).

2. If the shock binds when pushing the shaft through its stroke, then the shaft may be bent and will need to be replaced.

3. If the shocks from left to right do not feel consistent when compared to each other, or have built up too much air inside (feel empty when pushing the shaft through its stroke), then you will need to rebuild them following the steps outlined on page 19 of this manual.

Properly maintained dierentials are essential for a smooth operating vehicle. Check all three dis regularly to make sure they are ﬁlled and operating as designed.

1. Remove each di and verify the dierential action is happening and is smooth. If there is any notchy feel to them, follow the steps below to rebuild them.

2. Open the di and pour out the oil. Remove the gears and pins to release the outdrives, then remove the seals. Inspect everything to make sure there are no damaged parts. If the seals are old or show any signs of degradation, replace them immediately. Re-lubricate the seals and outdrives, then rebuild the di following the steps on page 3 and 4.

Hinge Point & Drive Line Maintenance:

Dierential Maintenance:

Checking the hinge points while the shocks are removed from the vehicle is the best time to inspect these parts. The other items to inspect are the camber links, steering links and drive shafts. Follow the steps below every couple of weeks in order to keep the vehicle preforming at the maximum level.

1. With the shocks o the vehicle, check the movement of the arms, hubs, and spindle carriers. They should move freely. If there is a bind, then the inner or outer hinge pin may be bent and would need to be replaced. The arms should not have any play when twisted or moved in any direction against the hinge points. If there is excessive slop present, then the arms or hubs may be worn and will need to be replaced.

2. Remove the camber links, steering links and servo link from the vehicle. Check the movement of the spindles to see if they turn freely. If they don’t, then check the kingpin shoulder screws to see if they are tightened down too far. Also, check for slop. If there is excessive slop present, then the spindle carriers may need to be replaced.

3. Check the steering rack to make sure it moves freely. If it binds, then the screws holding the Ackermann or the steering posts could be too tight. If they still bind, then check the bearings and follow the steps above to clean them.

4. After re-installing the camber links, steering links and servo link, check the movement of the rod ends on the ball studs. If they have excessive slop or are binding, then they may need to be replaced.

5. Check the drive shafts by rotating them. Look for any wobbles. If they are bent, replace them immediately.

6. With the drive shafts removed, check for slop in the CV area. If it is present, then reposition the CV pin to another fresh hole, re-lubricate and install back into the vehicle.
