General question 常见问题
Why Mini-z?  What's so fun about?
There are way too many reasons why people felt for this scale of RC racing.  One of the main reasons I like it so much is because the setup for the car is rather easy, and requires less maintenance/setup time, and I get a lot of track time as a result.  Another reason being the whole setting of chassis/body/track allows people to learn and train driving skill with less worry about collision.
为什么喜歡Mini-z? 有什么好玩的?
喜歡Mini-z的原因有很多, 其一它的设定相对的简单, 需要維修及改设定的時間相对小, 因此玩车的時間也比较長。 另一个主要原因是整个车身/车壳/跑道設計都比较友善, 车手可以放心盡情的飚, 而不需要过分擔心碰撞。

What are the differences between 90mm, 94mm and 98mm chassis length?
By setting up the car in different car length, not only can you use a body in a different car length; but the driving characteristic will be different as well.  Longer car usually(also depending on the car body/weight distribution)bring more stability to the chassis, while the car may become a little more understeer.  The vice versa holds true.
90mm, 94mm, 98mm的车身長度設定有甚么分别?
除了可以因车長不同而用上不同的车壳外, 车的駕驶特性因長度而改变。 视乎车身(壳)重量分怖, 一般说, 長车身的车會比较穩定, 同時也有可能比较"推頭"; 相反, 车身较短的通常较靈活, 但穩定性可能较差。

Why is my car running or steering is in reverse?
1)check your remote to see whether the "TH-reverse" or "ST-reverse" is set normally(on EX1UR or EX10), or to see whether your throttle or steering is in 'reverse' mode on your radio.  2) Check the motor wires connection
为什麽我的油门/轉向控制是反的?
1) KO控上可查看"TH-Rev"或“ST-Rev", 是否设定反了。2) 查看电机的接綫是否反了。

What are offsets?
Offsets may mean different thing in MR02 vs MR010(AWD), and all you need to remember is with more offset, even the wheels' width stays the same, the wheel will stick out more(wider track width)
Offset是什么?  
Offset在MR02或MA010上不太一樣, 但基本上说, 多点offset, 你的輪呔會更往两旁伸出更多。

Can I use MR02 wheels on MA010(AWD)?
No.
MR02的輪子能用在AWD上嗎?
不可以

What is the difference between clear plastic bodies vs. the grey/blue chassis?
Clear plastic body uses a harder material, yet it is more brittle; while the grey/blue material uses a slightly more flexible material, yet more durable in general.
透明车架和灰藍车架的分别在那裏?
透明车架用的物料以较硬及脆, 但灰藍车架则较韧及不易裂。

I am using the stock motor, and the car will stop dead in the track after some driving and will restart in a few minutes...why is that?
You may see a square mud-yellow components attached to your motor wire, that is a sensor that you might have triggered during your run, and it will cut all power to the motor.  Simply removing that should solve the problem.
我用的是原厂电机, 为什麽跑了几分鐘车就不動了, 但多等几分鐘车又可以走了?
在你的电机上可能有一个泥黄色的电路保護零件, 把它焊走了應該能解决问题。 有時候, FET升级造得不好也可能有这个问题。

I turn "on" my car, but it won't move at all?
Couple of possibilities
-Dead/low car/remote battery
-Poor car battery contact to battery terminal
-Battery power wires are not hooked up well with the board
-Radio is off/wrong crystal
-'On/Off' switch wires are broken or loosen
-Antenna wire is broken/loosen
-Wrong 'profile' selected on your radio
我车上的开关“开"了, 但车不動, 何解?
可能原因如下:
-车上/遥控上的电没电了
-车上电池接觸不良
-车上电源綫和电路版之间没连好
-控没开, 或用錯晶体了
-车上开关和开关綫没连好
-天綫继了
-控上的設定用錯了

I turn "on" my car, but only the steering works?
Possible reasons, but whatever the reason, don't keep pressing for the throttle and you might ended up with burnt FETs(if it is not already burnt)
-low battery
-motor wires are not hooked up well or loosen
-Throttle FETs were burnt
-Damaged board
-Mechanical issue(wrong motor spacer, stuck drivetrain)
车上的开关“开"了, 但只有轉向能用,油门不工作了, 何解?
几種可能性; 但不管是那種可能性, 盡量不要老加油, 否则可能會燒FET。
-没电了
-电机綫继了或松了
-FET燒了
-电路版坏了
-机器问题(用錯了电机墊片, 傳動部份有卡着的地方)

My car will automatically glide forward/backward when I turn it "on"?
Possibly too much trim, either forward or backward
为什么我一开车, 车會自動向前/後走?
可能向前/後的微調量不合適, 調到中立位就好了。

Why does my car keep on losing control?
Many possible reasons, and I will divide them into three area:
1) On car/remote
-Receiver wire is too close to the crystal
-Receiver wire is too close to the motor wires
-Loosen receiver wire
-Car battery is low and/or remote controller is low on battery
-Crystal on car does not match the remote crystal
-Damaged crystal
-Burnt Fets
2) Surrounding
-Room is too small
-track is close to wall and power outlets/electric appliances
-Exposed pipes/metal surface close to track
-Interference with other radio
为什麽我的车老失控?
兩方面入手看:
1)车上/控上有关的
-接收綫和晶体太近了
-接收綫和电机太近了
-接收綫和版的接位鬆了
-车/控没电了
-车/控的晶体不是同一对的
-晶体坏了
-FET燒了
2)周边環境有关的
-跑的房间太小了
-跑道和电器/电插位太近了
-外露的金屬面/管道
-受其他控的干擾

My AWD/mini-z cannot go straight?
-Try trimming on your remote(on board, if AM board)
-Check whether you have over tighten the wheel nuts
-Check tire wears
-If the problem is not 'consistent', then it might be a radio problem.
我的车直綫跑不直?
-用微調調好, 一般在控上就可以trim好了, 如AM版在版上也有調位(但建議先调控上的)
-看看輪子丝母是否太紧
-看看四个輪子的磨耗是否很不一樣
-如果这直綫问题出现没有规律, 可能是干擾问题。
 
Why does my car make a lot of noise?
Many possible reasons, some may include meshing of the gears might be wrong, broken bearing in motor(yes, that does happen), gear/differential scraping parts of the car, overly loosen differential, broken gear diff, loose body clip contact with body, etc.
为什么我的车在跑的時侯有很多雜音?
很多可能性: 可能是齒隙造得不好(掃齒), 軸承坏了, 齒輪/差速摩到壳/车身, 差速太松, 齒差速坏齒, 车壳和车身接合太松等...

My car won't reverse?
If you are using 2.4G, then play with the trim and find the proper setting.  When the car is trimmed too much forward or backward, it may cause the car not willing to go reverse.
我的车後退不了?
如果是用2.4G的, 試调整一下前後微调; 當车微调太向前或後的時侯, 會有影響的。

How can I make my car go faster?
There are many factors that will affect the car speed.  To begin with, I recommned trying the following:
-Full bearing for car
-Use rechargeable batteries
-If you are using stock motor, remove the circuit breaker(the mud yellow component on your motor wire)
-Install faster motor/FETs upgrade(beware some faster motor is mandatory to have FETs upgraded)
-Use after market radio (EX1UR, EX10, etc)
-Keep on Driving/uating/Tuning/Improving
什樣我的车能跑快一点?
很多會影響车速的原由; 從开始粗略的说, 我提意:
-全车上轴承
-用充电池
-如果在用原装电机, 焊走那个在电机电綫上的泥黄色电子元件。
-升级FET及用快一点的电机
-用高级的遥控(如EX1UR, EX10...)
-不继的練车/检討/调车/改進






Racing 比赛
If I want to race my mini-z, what are the essential parts I need?
Full set of bearing, ball differential(s), proper tires, suspension springs, motor, fet upgrades(if running a powerful motor), proper shell, possibly a better radio than stock radio and most important of all, a good mindset.
如果我想参加Mini-z的比赛, 我最基本的需要什么呢?
全车上轴承, 珠差, 適用的呔, 懸掛零件, 电机, FET升级(如果用暴力点的电机), 適當的车壳, 最好有高端的遥控及最重要的--良好的心態。

Why is my car moving so slow compared to others' cars?
Slow and fast are relative terms, and sometimes the 'fastest' car on a straight road may not be the winning car in a race.  Purely from academic purpose, to go fast on straight, you may need to consider the following:
-using good/matched RC rechargeable battery(faster) vs household rechargeable battery(fast) vs alkaline(slow)
-gear ratio
-motor used
-FET upgrades
-setup/suspension/handling
-body used
-driver's skill
为什么我的车比其他人的慢?
"快"與”慢"是相对的, 很多時候(直綫上)最快的车并不一定能赢得比赛。 单從学术角度, 要车在跑得快, 你需要考慮如下:
-用好的/精選的RC專用充电會比一般家用充电/碱性电會好很多
-齒比及电机
-用升级FET
-設定/懸掛/操控性
-车壳
-駕駛技術

Battery and charging 电池及充电
What kind of batteries will you recommend to use/more punch for race?
Got to be rechargeable if u want least bit of performance.  As for Mini-z racing oriented, any well-known matched batteries will do good, more commonly found rechargeable AAA RC batteries will include Orion, Muchmore, Intellect;  some well known rechargeable batteries(but less performance) are duracell, enegizer
那種电池你會比较推介比赛使用?
一定是充电池啦, 较有名的精選电應该ok, 而大厂出的RC充电也很多颇好用的, 如Orion, Muchmore, Intellect...如果一定要用家居常用的, 金霸王, GP,勁量等。

How much Amp should I charge my battery with?
I do strongly recommend to charge only 1C or below(meaning the capacity of your battery, if 900mah, charge it with 900ma), unless it is otherwise instructed.  Though higher charging amp will result in more punchy battery, it also might reduce battery lifespan and may even cause leaking or explosion in extreme cases.
我應该用多大电流去充电?
我强烈建議用家用1C或以下的电流去充电(指如电池容量是900mah, 用900ma或0.9A去充), 除非电池另带说明。虽然高A数充电的电比较爆, 但往往會减低电池壽命, 甚至也见过有爆炸的。

Is there a way to calculate how long will my battery to complete charging?
The actual charging time usually depends on many factors, charging current, way of charging(linear, step, etc), actual charged capacity, battery capacity...
But in theory, your charge time will be equal to your battery capacity divided by your charging current.  For example, if your battery capacity is 900mah(0.9A) and your charging current is 1000ma(1A), then your charge time will be approximately 0.9 hours(54min)
有方法能計算我充电的時间嗎?
實 際的充电時间是多種因素决定的, 充电电流, 电池容量, 實際能充入容量, 充电方式(直綫式, 階级式...)等...但一般按理論说, 电池容量除以充电电流可以得出一个大约的時间; 以如说, 900mah的电池容量, 用1A(1000ma)电流充电, 那么充电時间则大约是0.9小時(54分鐘)

Can I use alkaline battery in my car?
Sure, but the car will go slow...and DO remember to remove the batteries once you are done.
我可以用碱性电嗎?
當然, 但车會较慢…千万要记得玩完後, 把车上电取下

Can I recharge my alkaline battery?
NO, period.  Do that and you may burn your house down...
我可以充碱性电嗎?
绝不能, 除非你想燒掉自己的房子…

I hear hissing noise from the battery when charging, is that normal?
No again.  It meant the battery is leaking gas(rapidly)and on a verge of potential explosion...immediately disconnect the power to the charger(from a distance), and wait a short while until the battery is cooled down and remove them from charger(do touch by hands if chemical is leaked and covering the battery)
我聽到充电時, 电池發出"絲絲"的叫声, 正常嗎?
肯定不。 很有可能电池在(急速)流出液体或已在爆炸的旁沿, 立即把充电器的电源关了, 保持距离, 等电池冷却後, 才小心移走及掉棄电池(如有液流出, 不要用手去碰)。

My rechargeables are leaking during charge...can I continue to use it?
Better not.  It probably mean something is wrong with that battery, and continue using it may damage your charger or car.  You may ended losing more than you save.
充电時, 电池流液了, 我还能用这电池嗎?
最好不要。 电池已出问题了, 继續用有机會會流到充电器/车上, 得不偿失。

What will you recommend for charger?
High-end RC charger are probably good for matched batteries, such as ICE, LRP pulsar; since they are less prone for false peaking.  Other chargers I do use is the Powerex Maha or BC900
你有充电器能推介使用嗎?
一般较好的国外大厂RC充电器應該不差, 如ICE, LRP pulsar; 其他的我會考慮Powerex Maha 或BC900






FET related  (FET有关问题)
What is FET?
I'm not an EE person, but according to Wikipedia.org, FET is defined as The field-effect transistor (FET) is a type of transistor that relies on an electric field to control the shape and hence the conductivity of a 'channel' of one type of charge carrier in a semiconductor material.  Kinda jibberish to me, but I understand it as the electrical components that will control your servo motor and throttle motor.  Generally speaking, FETs that have higher current capacity with lesser resistance will allow a 'faster' motor to draw more current from battery to power it.
FET是甚么?
小弟不是电子專业, 借用百度知道的解詮: "场效应晶体管(Field Effect Transistor缩写(FET))简称场效应管.由多数载流子参与导电,也称为单极型晶体管.它属于电压控制型半导体器件."  个人理解是低阻而又有高电流特性的FET, 可以供更大电流给玩家的强力升级电机。

Should I upgrade my FETs?  Why do I need it?
Only if you need to install faster and 'hotter' motors will you really need FETs upgrade, also if the original FETs are not as 'linear' or they are damaged.  If you are doing fine with your current motor and already find it a handful to drive, I'd recommend to hold back this decision.
我應该升级FET嗎? 我为什么要升级它?
換FET的原因有二: 1) 原来的FET燒掉了 2)车手要用更强大的电机(而现用的FET供电不足, 會燒FET)
如果你现用的馬達在现有的場地而感到开不来, 最好还是留待以後吧!

I smell something burnt on my car, what's happening?
Very likely you have burnt your FETs on car, time to change it.
在车上有一股很濃的焦味, 怎么了?
很有可能你的FET已燒了, 最好驗正後换掉。

Where could I get FET upgraded?
Many local tracks or online shop will provide this service to you, generally speaking, they will charge you for the labor and the parts.
那裏能升级FET?
很多有場地的或遥控店都可以, 通常要收一些手工费及零件费。

Can I do it on my own?
Yes, but you have to be decent with your solder iron and have all parts ready.
我能自己升级FET嗎?
當然可以, 但你需要有枝好点的烙鐵及相應的零件。

Why would my fets be 'burnt'?  Or why my newly installed fets are burnt?
There are couple of reasons for that:
1) Fets weren't installed/soldered on properly
2) Fets are of poor quality
3) Way too much resistance from drivetrain(wrong motor spacer, tight axle...)
4) Short circuit on the board
5) Motor is drawing more current than the fets could support
为什么Fets會"燒掉"? 或为什么新装的Fets會"燒掉"
原因可能如下:
1) Fet没焊好或焊錯
2) Fet質量问题
3) 车子的傳動阻力太大(馬達墊片用錯, 中軸不顺...)
4) 电路版上电源短路
5) 馬達耗的电流比Fet所支持的要大






Autoscale or body 车壳
What body will fit the AWD chassis?
Usually, all shells that will fit the AWD chassis will always fit, the shells that fit MA015 are also pretty easy to fit onto an AWD...but some MR02 shells will need refitting.
AWD能用甚么车壳?
通上標上是AWD的一定都可以。 大部份MR015的也可以, 但部份MR02就需要加工。

Where do people get those outlandish body?  Do they paint it themselves?
Online or local hobby shops.  Yes, many white shells to select from and paint/decorate by oneself.
網上常见到一些很花巧的壳, 那裏能找到?
有些是京商出的, 網上應该能找到; 有些则是手工制的白壳

What body is good for racing?
There are a few off top my head--350Z, NSX, any Ferrari, any Lamborghini, etc
什么壳可以用作竞赛?
简單想, 350Z, NSX, 任何的法拉利, 任何的林宝堅尼…
