DIY-Awd 改(己加bumper)

Lipo goes with a balanced charger. Learn enough please to handle them because it is potentially hazardous.
Search the net using the code I gave you and you will find a factory in Lei Yue Mun. See if the factory has leftovers.

thx, 老師.
it is quite a joke that i even not have any awd.
but for the calculating, the cg at the front part will let the car easily for drifting. is it?
can you pm me for the address where to get the cells.
i really want to buy it.

1. If it is for drifting, what's the point of adding the 3rd differential?

2. Search the net please using the code.

1. i want to know about the theory for drifting. is it the speed of the front wheel gives bigger force so that a car can be more easily to drift. if it is , then the use of the 3rd differential is to give the front wheel have bigger force.

2. i have searched... it just show me factory in china....no one in hongkong.....
should i search in google or yahoo?

1. Wrong concept. Mid-differential is used because front wheels rotate more than the rear wheels when the car turns. Search the net and learn more.
2. Yahoo. Result 2. (Read carefully & be more independent!)

3個差速系統.modification, the true spirit of RC 4wd!   

i have read about it.
i have a few points about cg.
as the calculation in applied maths, even if i put the motor like this, the cg will just rise for about 2-3MM,(this is due to the point that i will add steer bar at the bumper for easily drfiting)
i want to ask, if 2-3mm will not affect the car performance so much, should i continue to do it like that to have a bigger room for the servo, pcb and the battery?
p.s. i will use the standard electronic stuffs in 1/10rc in this car.

I think u are making this tooooooo complicated.........
use 1/10 electronic ??
what scale is this car ?? Likw ABC 1/24 ??

1/28. likte others awd miniz.
i have managed the room for 1/10electronic.

although the actual rise height is 2-3mm, when compared to the total height, it has a significant effect already
rise height - total height  ratio is an important factor

then, what should i do now.?
i really want to use the 1/10electronics to do it, but the room is limited....
i can't put the motor lower....
Do you have any good ideas?

2-3 mm is a lot already. The ride height of an AWD which is able to run fast is usually 1-2mm only.

If I were you, I would redesign everything.

老師, can you suggest a way that i can put all the 1/10 stuff in it without rising the motor height?

1. smaller battery
2. 3110 servo or similar
3. specktrum receiver
4. Xray ESC (300) for 1/18 but no reverse
5. reduce the size of the mid-differential and put it near the rear differential to give you more space for other things.

In fact, you sacrifice so many things.

sacrifice?
1. smaller battery....maybe i can found it.
2. i prepare to use it too
3.  very expensive...
4. i have a same size...
5.....size reduce?

I meant you have to do a lot just to add a mid-diff when I used the word 'sacrifice'.

3. Look for Taiwan FMs then (beware of interference)
5. the middle shaft is too big, reduce the diameter (other than the gear) to provide more space. Understand?!

got it.
but the best way i think is using brushless......(just kidding)
i will think about it.
