Hi Guys,

What's the most powerful motor for stock AD PCB?
I'm using Atomic Stock R for my AWD but seem that the punch is not enough.

I used to use the PN racing super capacitor but one of my friend accidentally ripped off the wire and i couldn't attach it back.

I need a motor that has a high torque coz i don't want to change the fets on my AD PCB.

Thanks.

You could step up to the Atomic Superstock (Yellow Label). It has beastly strong magnets, and it runs great in my Awd Xmod.

Speaking of magnets, if you want high torque, look into Neo-mags. I hear they're a good upgrade for people who want power.

errr is there any atomic superstock motor around? or is it the 3Racing Superstock?

Anyone use Atomic T2 on stock AD PCB?

On the RCAtomic site it's listed as the Ballbearing Stock Motor, but I got it from AM where they had it listed as the "Atomic Superstock".

I personally haven't, but my friend has. Can you say " TOAST " :eek: The fastest motor that I tested on a stock AD PCB board is the PN S03 motor. I was very skeptical at first, but as of this day + two years, the board is still good with no burnt out FeTs.

i run the chilli motor on a stock ad board

i run the chilli motor on a stock ad board
wohoaaa the minimum requirement for chili is 2x2 4562 fets, how in the world the board can handle chili?

ur running it on AWD or 02?

im running it in a 02 it was clocked at 44 kmh it is a beast

i guess maybe it's ok only for MR-02, anyone tried the stock AD PCB with modified motor?

i might give it a try but kinda scared the fet might burn till the board cannot survive. :0

i only get about 7 min run time with it

What batteries are you using? What gearing? The Stock R is a very fast motor when geared correctly.

If you must have another motor, try the older Atomic Stock motor. More torque, less RPMs, so it should fit the bill.

im using 19/29 gearing on my AWD with Atomic Stock R, kinda fast but im supprised christian tabush said Stock R is faster than T2 and Chili.

i am now running a NML LIGHTNING SS ....tons of torque. it suits my drive style :D

NML on stock AD PCB? the old NML heats up badly till the fets fell off haha

i ran the new nml on a 2x2 ad band pan car.....10 min of solid run time....w/ intellects and 12 min solid w/ orions.......
he is also building speedys for stock cars.....that would be able to run down the straights with my full mod pan's

2x2 of which fets?

2x2 of which fets?
3010.... if you ran it with a 10 tooth you would see approx 38 kmh with way too much punch for a 2wd..... should be perfect for an awd
also the motors that he has been building for stock cars....unreal :eek:

Keep gearing the stock R up. The motor has tons of power. Power is a function of RPMs and torque and is calculated in watts. The higher the wattage a motor puts out, the faster the motor will be. My guess is your batteries probably are not handling the discharge current of a properly geared Stock R. Try intellects in the car and see how it flies.

A T2 is fast top speed wise but has very little bottom end. What this will do is give you a car that screams at the top but will have little acceleration. You can gear it down to accelerate quicker, but it won't be as efficient.

The Stock R can keep taking bigger and bigger pinions and still maintain its efficiency. The motor will actually run more efficiently at lower RPMs ~14,000 or so. By putting a bigger pinion you keep the motor on the RPM range you want (~14000). The car will still accelerate hard because it has tons of torque and get tons of top speed from the long gear ratio.

ur talking about Stock R on MR-02 rite? how about on an AWD? what gearing do u use for Stock R?

CristianTabush
2008.01.15, 02:05 PM
NO I am talking on the AWD. Gearing is entirely up to the specific track. At the Atomic Cup this past weekend I ran a 20/29 ratio. The car was very quick.

oic, ur running on PN Racing new gear ratio thinggy...does those numbers really give great effect than the stock gearing by Kyosho?

Here's the trick:
AWD motors - you need a motor that has more on the torque side, rather than RPM. This is due to the drive train. Reason: with so much resistance, due to the extra gears, you need a motor that has tons of torque to get it going. You then can gear up to get good top end, while compromising very minimal torque, because that, you have plenty of.

MR-02: because it's direct drive, it's more forgiving. You can almost go both ways, depending on the track size.

If I may ask, how and where do you run your AWD? I will need the following:

1. Track size?
2. Technical or fast track? (lots of turns or minimal turns w/ lots of straights?)
3. How many minutes?
4. Gearing? what pinion/spur do you use?
5. What kind of batteries?
6. AWD or MR02 or Both?

1. Track size? - medium track around 20 x 45 titles
2. Technical or fast track? - Lots of turns
3. How many minutes? - 5 min race
4. Gearing? what pinion/spur do you use? - 19/29 on Stock R, 17/31 on Speedy 07
5. What kind of batteries? - Vapex Instant, Vapex 1000mAh, Sanyo Eneloop
6. AWD or MR02 or Both? - AWD

20x45 tiles??????is that rcp??? 50cm or mini 96?......if thats th big tiles thats a huge track compaired to what we run here in cali
:D

hehe, bigger than mini 96...i think about 3-4 wide L used to build the track

There are other factors (ie gearing vs. trakc size, type and how many fets) to be considered and it can't just be blamed strictly on the motor.

Back to your question:

You're using weak batteries, in my opinion. How about trying the Orion 900's, or if you wait a little longer, the Team Scream matched cells. There is a world of difference between the eneloops, the intellects, and the orions. Basically, you need batteries that world champs and other top notch racers don't....punchy and lots of power....Orion 900's is your answer. Eneloops, in my opinion, are good, but probably not for your application.

Also, play around with your gearing. Gear down, if you're lacking torque. Make sure the gear mesh is smooth, no binding. Feel the fets...are they warm, if so, that's where all your power is going...waisted heat, which will eventually turn into crunchy, fried fets. Yummy!

Yasuji,

Your AWD is pretty fast and zippy.
