GP-3 IN BANGI SELANGOR
It is true , it hard to bit the old timer ( Otai ) in this 3rd GP in bangi selangor (MRCH).
Yes in Race anything could happen,
My car was flip over due to accident in the race and some more is a lot of mistake that I have done,
I try the best to chase the Otai but finally just in 3rd Place.
Next !!! Will be in Klang Selangor ( IRC ) for 4th GP , it will also anti-clock wise.

MY NEW MOTOR NOT DISSAPOINTED ME !!!
My new motor Speed07 is great !!!
A bit more punch compare to my previuos motor. Smooth driving. I like the way it is.
Now in progress of training for 3rd GP in Bangi Selangor with new style that is Anti-Clock Wise.
It quite difficult but need some training to make use to it.
I will try my best for this coming GP in bangi.

JUST BOUGHT A NEW MOTOR FOR MY MINI-Z
To do this I have to search some information what kind of motor I should use.
My curent motor it have :
1. Normal Magnet.
2. Armeture
3. Bushing
4. Carbon Brush
The performance it OK but it Hot when running for about
10min ~ 15min.
So I'm looking for new motor that have :
1. Normal magnet
2. Ball bearing
3. Air Ventilation
After searching thru internet & friend so I decide to use S07
Details Of S07
The Speedy 07 is destined to be the motor of choice for Mini-Z stock class racing. This motor can be used with stock FETs and is 30% faster then the Speedy 05. The Speedy 07 is equipped with bearings at both ends of the can and an all new endbell design to increase cooling. All new high performance carbon brushes.
Feature
- 30% faster then the Speedy 05
- 50 turn balanced armature
- New endbell design for increased cooling
- High performance carbon brushes
- Ball Bearing can, front and rearPerformance
–no loadSpeed = 30,453 RPM
- Current = 0.726 AMP

HOW TO CHOOSE MOTOR FOR YOUR MINI-Z
1) Why Dyno a Motor?
"Judging a motor's performance based on RPM is like judging the weather based solely on temperature. If it is 80 degrees outside, you can be fairly certain it is not snowing, but is it sunny or raining?" - Facts Machine instructions
In other words, the RPMs of a motor are only telling you one side of the story. Two identical motors can top out at the same RPM, but which one gets there quicker? If one tops out after 3.5 seconds, and the other one tops out at 2, are they still the same? Certainly not. The difference between these two motors is going to be the TORQUE each motor makes.
2) Power
Power is the most important number when looking at an electric motor. It usually is measured in watts and it is the result of the multiplication of RPMs and torque. In the case of the motor discussed above, the second motor gets to top speed quicker, therefore it has more torque. Since power = torque x RPMs we can assume the second motor makes more power.
Power is important because it tells you how to gear motors. The more power a motor makes, the faster it is going to be PERIOD. What I mean by faster is the motor will not only accelerate faster, but also have a higher top speed. This will be the case, if the motor is geared correctly. A motor with tons of RPM and little torque, will need a small pinion. A motor with tons of torque will need a huge pinion and a motor that has a solid combination of both with need an intermediate size pinion.
3) Motor Selection
In order to be able to move on to gearing you have to understand how to select a motor for a specific track. Typically on smaller layouts, you will select a motor that makes LESS power, as it will make you car more drivable as well as allow you to gear it better suited to its power characteristics. By this same logic, on larger tracks, you will select a motor that makes more power in order to take advantage of the motor to its fullest potential.
Selecting a motor correctly is important because if a motor that makes large amounts of power is geared with too small of a pinion, the car will become impossible to drive since it will have too much wheel spin. If it has too large of a pinion, it simply will be too fast to maneuver around a tight course.
4) Gearing and the Graphs
Once you have selected the motor best suited for your application, the next important step is to understand how to gear them. With the aid of the graphs from the Dyno tests we can learn how to associate gear ratio with POWER band. What is the power band you ask? The power band is the curve of RPMs v. Torque of any given motor. It will tell you where in this range the motor will make the most power.
The easiest way to look at this is to see where the motor makes the most power in the curve. At this point, the motor is yielding its highest combination of torque and RPMs. This means that at this point, the motor will be at the highest speed it can get to quickly. If the correct gearing is chosen, a motor with more power should accelerate quicker and have more top speed than a motor with less power.
By looking at the graph, you can also tell if a motor makes power based on RPMs, torque, or both. If the graph is skewed towards the right, this means the motor makes more power higher in the RPM range. This is typical of high RPM motors such as the Chili and Anima 2. In the case of these motors, you want to use a small pinion on your car in order to keep it operating on the higher end of the power band (the motor spinning at high RPMs).
If the power graph is skewed towards the left, this means the motor makes a lot power out of torque. Motors with high torque, such as the Atomic Stock and Atomic Stock R love big pinions. They have the grunt to move the large size pinions and make top speed based on long gearing (big pinions). A big pinion will keep the motor operating in the low range of the RPM Range, where it makes its most power.
Conclusion
When selecting the motor you are going to use, don't go for what is fastest or makes the most power. Select what is best suited for the specific application you are going to be using it for. Each track has different characteristics that make motor selection very important in order to get quickly around the track.
Even though the above guidelines are not written in stone, they are great aids in understanding how motors operate and what you are looking for when selecting one that best suits you and your track.

GP-2 ( IRC KLANG )
This time race is so challenging due to a few of old timer ( otai ) joining the race.
In the final race I could'nt catch up after one of the otai overtake me due some accident happen.
Finally I have to give the first place to the otai , and I manage to get 2nd place.
It was so much challenging and fun too.
I have to change the engine to new one coz the old engine is kaput already... hehheee
What's important is the friendship and information sharing in setting the mini-Z car !!!!

GP-2 IN IRC KLANG
I'm in progress of preparation for GP-2 in IRC Klang.
The most important is your skill , focus and stay calm or cool.
From my Experience , there is no need to use exspensive remote controller , even using the standard remote controller with the skill you have is enough to be competitive to others.
Use what you have first, master it , control it. Don't let them control you , you must control them.
Happy Racing !!

SERVICE MY VARIABLE RESISTOR (VR)
Last night I check my MINI-Z car , especially the steering , I just realise that when the Car in max speed the steering will move by it self to the right. This symptom will cause your car not in the straight line in max speed.
Therefore I open the chassis and have a look to the VR , open the plastic cover , spray with air and put a drop of WD40. The put all the part together again then check.
I notice the symptom is gone .!!! :)
Tonight will give some try in the track!!!
Happy Racing !!!
THE BEST AND MINIMUM SETTING FOR MA-010
For the best setting to the MINI-Z car ( AWD MA-010 ) :
1. Must Use BEARING
1. Must Use BEARING
2. Change rear diff to BALL diff.
3. Use GT BodyShell
4. Change Rim follow bodyshell offset. ( Front = +3.5 , Rear=+2.0 )
5. Tyre setting : Front = 30 degree , Rear = 20 degree.
6. Spring setting : Front use HARD , Rear use SOFT.
Use the stock motor first until you can contol the car !!!! After your skill improve the you change the motor to X-Speed for AWD!!!! Then practise again until you can handle the Car !!! This motor is enough to enter the race !!! Happy Racing!!!!
