What is droop? Droop is the amount of down travel that your shocks have. With adjusting droop you can greatly affect the way your car handles. As you increase your front droop (making the shock longer) you will smooth the car out going into the turn and gain steering on the exit of the turn. As you decrease your front droop (make the front shock shorter) your car will initiate the turn quicker but will have less steering coming out of the turn. The car will also have a more responsive feel. For the rear, as you increase the droop your car will gain more side bite and traction. As you decrease the rear droop, you car will become more responsive and will have less side bite giving you more steering. Normally on low bite tracks such as parking lots you will find more droop will increase traction and hook your car up. On high bite tracks you will find that less droop will help keep the car flatter and increase corner speed and lap times. Droop is something that you should experiment with at your local track to get a feel for what it does and how you can apply it the next time you race.
Adjusting the droop on your XXX-S On the XXX-S you can adjust your droop by using the droop screws that are located in your bumpers on the bottom of the car. As you turn the screws clockwise you will decrease your droop travel. As you turn the screw counter clockwise you will increase the droop travel of your car. You want to make sure that the left and right side have the same amount of droop. This will ensure a well handling car.
Measuring the droop on your XXX-S
Most of the Team Losi drivers use the Team Losi droop gauge to measure their droop settings. On the front this is done by simply placing the flat part of your droop gauge flat against the bottom of your chassis right below the middle of the arm as shown in the picture. You then slide the droop gauge across until the steps of the droop gauge touch off on the setscrew boss of your caster block to your desired setting. For the rear, you do the same as the front except we measure off the center of the hub as shown in the picture. Again make sure that your droop is equal on each side.
Setting the Ride Height
What is ride height? Ride height is the distance between the bottom of the chassis to the track surface.
How do I set my ride height? The first step is to install all your electronics, motor, and battery in your XXX-S, as if it were ready to run on the track. To set your ride height you will need a ride height gauge. Several aftermarket companies offer ride height gauges and should be available at your local hobby shop or track. On your XXX-S you will notice that the sides of the chassis are slightly higher than the front suspension and rear suspension mounting area. This is because there is a slight angle from the center of the chassis to the very outer edge for clearance when rotating around corners. There is about a 1mm difference from the outside edge to the center of the chassis. The chassis is perfectly flat right below the front suspension and rear suspension of the car. Most Carpet tracks have a minimum ride height rule, you'll want to check with your track to see if these rules apply. These rules are made so that cars do not run too low and cause snags in the carpet. For racing on carpet, with 55-59mm tire, we like to run our cars right around 3mm ride height unless the track does not allow that low. As for asphalt or concrete tracks with rubber tires there normally are no ride height rules. For asphalt we run our cars right around 4-5mm ride height. You will find as you lower the ride height of your car it will free the car up through turns. On some of the team driver’s setup sheets you will see they run the car a little lower in the front. This helps the car steer into the turn and hooks the car up more when coming back on power.
"Tweaking" your XXX-S
What does tweaking your car mean? It is balancing the front of the car to the rear. By not having your car tweaked flat you may experience a push to the right and your car being loose to the left or vice versa. By adjusting all four shocks and making all four corners of your car evenly preloaded will result in a well balanced and smooth feel with your car. Before you can "tweak" your car, your XXX-S needs to be in good running order. Be sure that that all the ball cups rotate freely, the shocks are clean and operating smoothly and that all hinge pins and suspension mount points move freely. If any of these parts are bound in any way, this will affect the "tweak" of you sedan.
Setting the tweak on your XXX-S Following the first two steps of setting your droop and your ride height, you are now ready to set your tweak. You start by finding a flat area to set your car on. Make sure not to use your pit table because the wood is usually warped and not very flat. A lot of the team drivers use a set up board or a 3/16" thick piece of glass as a flat surface. Set your car on the board or glass upside down and find the center of the front and rear of the car. After finding the centers, mark it with a small drill mark or a score from your hobby knife on the center-edge of the bumper. This will make it easier to located the center of the car the next time you are setting the tweak. Now take your hobby knife (a lot of the top racers like to use a hobby knife to find the perfect center on their car. Please use caution when using a hobby knife for this exercise) or 1/16” Team Losi Allen wrench and push up on the center in the rear of the car with your tool. This is done on the rear bumper. If your car is not perfectly tweaked, one tire will start to rise before the other. In the picture below we find that the left tire rises before the right tire. This means your car is not TWEAKED properly. To fix this problem you will want to apply pressure to the left rear side and relieve pressure from the right rear side of the car. This is done by putting more preload on the right front shock (adjusting collar clockwise) and taking away a small amount of preload on the left front shock(adjusting collar counter-clockwise). Keep in mind when doing this you will only need to adjust the preloads of your shocks slightly to get the tweak corrected. You now have the front of your car tweaked flat with the rear. Now we are going to "tweak" the front end of the car. This is done the same way as in the previous steps. With the front end of your XXXs facing you, find the center of the car (use the bumper) and score or mark it like we did the rear. Now take your hobby knife or 1/16" Team Losi wrench, and slowly push up on the front until one or both of the tires come off the ground. If both front tires come off the ground simultaneously, your car is tweaked perfectly flat. If the left front (with the front of the car facing you) comes off the ground first you will need to apply more preload to the right rear shock (adjust collar clockwise) and reduce the preload on the left rear shock (adjust collar counter-clockwise). Check your tweak again until you get both front tires to rise off the ground simultaneously.
