RC Beginner's Question

i agree with yikl...  most rc players will keep the radio for a long time.  its better to buy a better radio at first.  however, if you have a tight budget, just get the entry level one (like 3pl).

Is the Yeah Racing Ultimate Brainpower ESC and a 10T set n e good? Is hobbywing n e good?( it fits my budget) lol

If my memory is correct, there also have a hobby shop at Highway 7 & kennidy(may be the spelling is wrong). But it is 10years ago, I am not sure it still here or not. The  boss is a Chinese guy. Everybody call him東哥

The Yeah Racing Brainpower RSC = HobbyWing ESC
there is a 35A and a 60A version.
35A supports upt o 9T, while 60A supports up to 5.5T
get the 60A version as its not that much more expensive, but you can use faster motors in the future.

One silly question, for the pinion gear does it have to match with the motor. Say like if i get a 9T motor, do i need to get a 9 T pinion? Cuz i dont rly get the ratio thing.

No, you have the wrong concept.

Motor: 13T, 12T etc.... or 13.5R, 11.5R ... 3.5R  are the rating/ speed of the motor.
The lower the number (ie 3.5R) the faster the motor.  Faster motors need higher rating ESC or else the ESC will burn.

For beginners, you can start with 13T or 13.5R (brushless)  if you want to save some $, you can also start with brushed ESC + motors (silver / black cans)

As for the pinion, it is the gear that connects to the motor.  Lower teeth pinion gives 'better' accerleration, while higher teeth pinion gives 'better' top speed.  You cannot use too small pinion or too high pinion else the motor will get too hot and burn out.

Usually when you buy a specific car, the manual will tell you which pinion to use for a given motor.  

the final drive ratio (FDR) is a formula, which is like this:
(Spur size / Pinion size) x (Internal Gear Ratio)  = (FDR)

The internal gear ratio is different for each car.

lots of info there!!!  good luck.

Thx for the tips and help. If i go with TB03 instead of TB03D, what kind of setup do i need for drift ( feel like doing both racing at parking lot and doing drift).
Is it possible to have 1 car for both drift and race?
And as for gear ratio, is it the lower FDR, the better( meaning closer to 1:1). From the TB03 manual, the 64T Spur Gear with a 27T pinion has 5.77:1 gear ratio, what does that mean? Im still abit confused after reading the thread of gear.

I live in Toronto. I getting the stuff when i visit HK this summer. Im not sure about the TA05. I heard its a good car, but then i heard that TA05 is good if ur goin with racing on "flat" surface ( proper tracks), but not good for parking lot and drifting

My private track is the parking lot and the back lane of my house.... haha~

My Ta05 drives fast, and can drift well.... it's all depends on your setting.

--> ...kind of setup do i need for drift...
Setup for drift:
1) Drift Tires (must)
2) Gear box setup.  Some people prefer Spool for front and rear. (optional)

Setup for Fast Car:
1) High grip tires
2) Rear usually ball diff.  Front can use spool/one-way/ball diff

--> Is it possible to have 1 car for both drift and race?
Yes

--> FDR
Lower FDR means faster for a given motor.  (but in the expense of heat)
Any motor would have a suggested range of FDR.  for eg: 13.5R motor, manufacturer suggests 5.0 to 6.5.... so its better to find gears to fit that FDR.

in your example: 64T Spur, 27T Pinion, FDR = 5.77...
since FDR = (Spur/Pinion)xInternalGearRatio
so InternalGearRatio = FDR x Pinion / Spur  = 5.77 x 27 / 64 = 2.43.

This means TB03's internal gear ratio is 2.43  (this number does NOT change, unless you change the size of the pulleys)

I remember 東哥 too, he had this small shop with a very small track next to his shop.  I think by the time I left in 1996, his shop was closed already.

Thx fot the gear ratio and setting help. I went to ask Advance Hobbies 2day (one at sheppard and Midland/Kennedy) n they said they can give me a TT01 + Fast Charger/Batter + Radio/ Servo/ ESC/ Receiver for total of $300 (around $2000HKD).

If i get a
TB03
Futaba Mega Tech 2PL
Yeah Racing 9T motor
60A ESC
Charger+ Batter
in HK, it will be around $2900 (based on rcmart price)
If i dont get the 9T motor n use the Stock
It will be around$2600

Which deal should i take? Im like 1516. Do u guys think i can get a better price at KWS?
Obviously i dont rly want to spend too much on it.
Please give me to advice!
THX

reference prices at KWS:
2PL(AM) - $300ish
Hobbywing 60A + 9T - $700ish
Charger + battery - $500ish
TB03 - dont know price
TT01 - from $6xx to $9xx (depends on body, option etc)

If you are coming to HK, get it in HK.  If not, get it locally or mail order.
I find RC prices in HK very cheap.

TT01 price in HK looks attractive, but is it "future prove"? Is it a waste of money to get a TT01?

no car is future proof. but tamiya tt01 cars is good for beginners because it has fewer, cheaper, and easy to find parts.  however, tb03 is newer than tt01... so in theory, tb03 should be more 'future proof'.

another consideration for you could be M05.  m class is quite fun and has few parts and m05 just launched!

One shop in KWS sell a set of tt01 for 9xx. I forgot whether it include battery/charger, but it include car, and all radio gear.

Will there be n e one goin to KWS and can get me the price for TB03 and TA05?
