TRACK SETTINGS TRACK SETTINGS RIDE HEIGHT Use the spring adjusters on the shock absorbers to adjust the front and rear ride heights. With the car level, we recommend setting the ride height to around 19mm on astro, 23mm on dirt and 14-16mm on carpet. (16mm if there are large jumps in the track). This is measured between the bottom of the chassis and the ground with the car in running trim.
TRACK SETTINGS REAR SHOCK MOUNT See Page 13 Bag D - Step 30 The middle hole on the shock mount (3) gives best all round results. Moving the shock to the outer hole will stiffen the suspension and increase the reaction of the steering. The downside is less compliance over bumpy sections of the track. Moving the shock to the inboard position softens the suspension and will slow the steering reaction making the car smoother over the bumps.
TRACK SETTINGS FRONT CAMBER LINKS See Page 03 Bag A - Step 05 The kit settings for the front camber link position (3) and length are used by the team for most tracks. A shorter front link will make the car roll less and speed up the cars initial steering response. This is a better choice for bumpy, low grip tracks. A longer front link makes the front of the car roll more and offers less steering reaction at high speed. We would recommend this on fairly smooth high grip tracks.
TRACK SETTINGS REAR ANTI SQUAT SPACERS See Page 16 Bag E - Step 37 The Kit build anti squat is set at 2°. This works best on most tracks, and with the included parts can be increased or decreased. Generally less anti squat allows the suspension to work better over the large bumps and gives more power on steering. Reducing the anti squat makes the car handle better over small ripples, but not so good on the tracks with large bumps.
See Page 12 - Step 29 We recommend the ball differential is used for loose or wet conditions. For consistent performance it is vital that the differential action should be smooth and free. Diff adjustment is not a tuning aid and the diff should never be allowed to slip. A loose diff can usually be recognised by a "chirping" sound when powering away from turns or landing under power from large jumps. Never allow the diff to run dry and rebuild the diff regularly to maximise it’s life.
TRACK SETTINGS RADIO TRAY POSITION See Page 20 Bag E - Step 44 Similar to adjusting the LiPo position, the radio tray can be used to adjust the cars weight balance. Running Kit Build forward position (3), you will have maximum steering and a settled front end while jumping. Moving the tray further back is better for twitchy or low grip conditions.
The LD2 provides the option to adjust the front pivot block height using spacers. The kit build pivot block position is high – 1mm spacer between the pivot block and bottom plate. The low position is achieved by removing the 1mm spacer from between the pivot block and bottom plate, and replacing it with the optional 1mm spacer between the link mount and top plate.
