Shock Filling Instructions For both front and rear shocks 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. Step 1. Start by drilling out the emulsion hole if necessary. 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.
Bag M Final Assembly TKR1403 Steering servo (not included) Note: We recommend using a low profile servo with at least 180 oz/in torque and metal gears. Running less than our recommended rating will increase the chance of premature servo failure. Step M-1 IMPORTANT RADIO SETUP TIPS, MUST READ: The Tekno RC EB410.2 is highly tunable, but can be very aggressive depending on track conditions and tires used.

Set Up Information 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.
Set Up Information (continued) Differentials Front: Changing front diff oil affects overall steering response. Thinner can increase off-power steering but the vehicle may be twitchy and harder to drive. Thicker can increase on power steering and stability. We recommend 10k to 20k in the front diff. Center: Changing center diff oil affects the front-to-rear drive balance.
Radio Information Please read thoroughly 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.
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. Bearing Maintenance: Bearings should always be smooth and free in order to preform their function. We recommend inspecting and cleaning each bearing on a regular basis.
