This article will guide you through the basics of setting up your camber on your Losi without the need of expensive tuning parts. We will describe the basic adjustments and how they affect the handling of the vehicle. This guide is not only for racers; also, bashers can have so much more fun when the car is adjusted correctly. So let us start!
1. Estimate the track
If you want to go faster, it is important to estimate the track situation. Most of the tracks are changing during the day when there is so much action. Starting on a flat track and ending on a bumpy track means a lot of mechanic skills between the races. Take your time to adjust the car, but do not worry, with the steps we will describe below it is much easier!
There are some links between the shock tower and the spindle hubs and that is not for the show! You are able to adjust these very easily and the changes have a direct affect on the handling of your car. The amount of camber does not affect your straight-line performance at top speed. It has everything to do with how you car is responding within corners.
2.1 Front Camber Link Length
As you can see on the above picture, the camber links are responsible for leaning in or leaning out the wheel position. Always use a negative link position so the wheels are leaning in the car. When you adjust the camber more negative on the front the car gets more steering and is much more responsive. Do not go any further than -3mm leaning in because you have not much traction anymore. A good starting point for almost every situation is -1mm.
2.2 Front Camber Link Position
You can also adjust the position of the link on the shock tower. There are three positions on the tower; the default position is the middle hole. Lowering the link will cause the car to be more responsive and will give you more off power steering. So when you are driving on a short track with narrow corners this is the position you want. The highest position will give you a less responsive car, a long track is ideal for this setting because the car is more stable when you are at high speed.
2.3 Rear Camber Link Length
Changing the length of the rear link will change the handling of the truck in corners. It will not make much difference on top speed. Increasing the length of the link (less negative camber) will make your truck more stable when you are entering a turn, it will also increase the amount of steering upon exit. But remember, always negative! This setting is ideal for narrow tracks.
Shorten your link (more negative camber) will increase the chassis rotation but will decrease the amount of steering upon exit. Therefore, you can use this setting when you are driven a large track.
2.4 Rear Camber Link Position
Lowering the link position will give you a much more responsive truck and increases the rotation of the chassis when you are off power. This is an ideal position for a narrow track with tight corners. Raising this link on the shock tower will make your truck more stable and provide more consistent handling; the negative is that this position will give you less chassis rotation off power (better for large tracks with big corners).
3 Hub Carrier
On the rear of the truck you will find 2 holes to mount the camber rod end. By going to the inner camber link on the hub you will gain more corner rotation entering and through the middle of the turn but will reduce on-power steering. The truck will also have more straight line acceleration and accelerate through bumps better. By default the link is attached to the outer hole.
4. Measurement Tool
Okay now we understand the meaning of the camber on your truck. However, how can I measure the amount of leaning in or leaning out of the wheel, aka camber? In almost every hobby shop, they sell a Camber Gauge. This is a tool that you can place on a flat surface and put it against the wheel. You can set the amount of negative camber with the tool and the only thing that you have to do is position the wheel so it hits the tool on top and bottom to find your camber.
