Review and Test Drive:

Basically, Mini-X is very different from any mini R/C cars available in the market. The independent
suspension system replaces the popular H-plate design to assist the steering condition. Firmness can be
achieved by adjusting the hardness of spring instead of hardness of H-plate offering a higher amount of
variables in track conditions. The Independent suspension design helps the mini-X run in most surfaces
with good performance. No ride height rings are necessary. The height of car body can be adjusted by simply adjusting the screw at the bottom piece of suspension arm. With the integration with front and
rear ball differential system, maximum traction of 4WD becomes possible. The front suspension system is not only responsible for its basic function of independent suspension, but the degree of camber and cluster can be adjusted in a very neat way. These two sub-functions can combine to make a wider range of steering response. The center of gravity of the car set is relatively lower than any mini-cars. This can be obvious found from the placement of battery, motor, ESC and Receiver. The factory ESC is powerful enough to drive a wider range of motor without damage. The strong and reliable radio foundation allows Mini-X to be played in any areas.

In other words, Mini-X can run in a high speed in a wider condition.

Focus:

Mini-X is really the most innovated design to the 1:24 scale. No matter if you are a beginner in R/C car
or a skilled racer, all can find the joy of playing this mini-X without any hassles. Although it is compact
design, it consists of full features of 1:10 scale models. Beginner can get start with this R/C kit easily
with a lower entry cost. Skilled racer can practice their skills with this portable mini-X at anywhere and
anytime. Owing to the factors of its compact size and wide range of running surface, it becomes
possible to run Mini-X at home.

General setup and maintenance procedure:

- A suitable tire should be installed depending on the different surface condition in order to
achieve the best traction.

- Bearing should be oiled from time to time.

- Shaft ring should be fitted to fill the gap over 0.5mm in order to achieve the best stability.

- Different strength of spring should be applied depending on different track condition such as
angle of corner, number of corner and full speed portion.

- It would be the best to keep the center of gravity down in order to increase the stability in all
condition.

- Motor should be cleaned with proper solvent

The inner space between the two front suspension arms on both sides must be increased. This can be
done by the following procedures:

- Setup the front wheel with your expected camber angle.

- Mark the position ball head position for the camber purpose.

- Remove the pin.

- Unplug the top A-arm with the ball head.

- Choose a suitable file to rough the surface including hex ball head towards the dog bone.

The abrasion should be stopped if the front independent suspension can move freely through the whole
course of the damping range.

The ball differential must be setup properly with the following procedures, otherwise, it will result the
problem of insufficient steering and slow response turning into a corner.

- Open the front and rear ball differential gear by unscrewing the screw inside.

- Face the front of the mini-x

- Unscrew the pin screws above the ball differential

- Put the ball differential out with the 8mm X 12 mm bearing

- Unscrew the screw on the inside the long tube

- Put grease onto each ball holes, low to medium viscous type are recommended.

- Reassemble it back by screwing in real slow

- Check the tightness from time to time

- Stop screw in when it JUST starts differential when gentle force applied on one side.

- Ball differential slippery is not a concern.

After having finished the front differential, adjust the rear with the similar procedure. However, it
should stop screwing in only when it is slight more than JUST starting differential.



Furthermore, mini-x has also taken care to model car collection! It is flexible enough to turn all static
models to live because Mini-X is a true 1:24 scale and it can be well fitted with different chassis at
minimal modification in a lower price, but more options.
