s104 2wd ?

jonathan may · #1 12-10-2013

has anyone tried to run there s104 as a 2wd yet like they do with the xray ?

You should be able to run it in 2wd the good thing is you can remove the front drive shafts too as it's the same as a rally cross car with independent axles

It should be possible to covert it to 2wd.
But you need more kick up on the chassis/ around 25degree i think?

I have seen such a 2WD in action on an astroturf race and it was as fast as the rest of the field. FYI it was a race with lots of International drivers...

ive tried it weekend just gone. its not too bad, but i found it needed a fair bit of setup work and alot of extra weight at the rear

rcpower · #6 21-02-2014

I can imagine that. I have run the 4WD with saddle (was about 1760gram) and then the front/rear bias was about 50%

I have built a 4WD with low-profile servo and shorties for my son: without additional weight it's 1642gram, without body, front 53% rear 47%
This will need about 60-80gram extra in the back

Now I have converted my 4WD with a shorty and the motor and esc in the back(as can be seen in the Sworkz thread). Without additional weight it comes in at 1685gram, without body, front 47% rear 53% This more looks like the real deal to me.

Both myself and Kevin Brunsden are running shorty, with around 80g behind the battery, and the 25g brass rear plate as well.

When on the scales this weekend gone, in 4wd config it gave us an exact 50-50 weight distribution. all 4 corners were identical.

The only modification we have done is to place the ESC on the chassis, and the receiver on top of the servo which makes a massive handling difference.

I have seen your conversion, and was tempted, but i dont see the point now as im hoping to have the new chassis next week

rcpower · #8 21-02-2014

On my son's car with the low profile servo the esc is also flat on the chassis, behind the servo.

It's such a great car in every aspect with so much potential, I cannot understand why there aren't more people already driving it. Perhaps it takes a little more time to convince people... With the new chassis it will just be brilliant for sure.

having said what i just did, im now in the middle of doing the conversion. figured i may as well start working on setup for new chassis.

only thing im not sure on is whether the esc is intended to be behind the motor or up front on the new chassis

Esc position in front of motor? Then you would have the vented holes in the chassis underneath the esc, great for cooling, but not so great for dirt. I don't know what to think about that honestly.

If the esc was supposed to sit behind the motor(left rear corner) the servo mounting holes could have been placed a little more inwards.. see link below.

If you measure the lipo (96mm length) and the motor length there will be place enough in the left corner. In the left front corner you could place a spare wheel ;-) or perhaps an old receiver which becomes very hot.

s22jgs · #12 22-02-2014

Chances are I'll go with the esc at the back and use the space up front for balancing weight

rcpower · #13 25-02-2014

Come on Steve, show us your "new" car.
I tested mine on astro yesterday and it was definetly better than the old config: much more agile, more level flight, easier to drive, more stable under braking.

s22jgs · #14 27-02-2014

had it out again on Tuesday night, and to be honest, i wasnt overly impressed with it. Prefered the old layout

rcpower · #15 27-02-2014

Can you be a bit more specific about "not overly impressed"? Chances are you found it a little less stable, but
did you add a small bit of weight in the front? Did you readjust dampening/spring? I am sure that with some finetuning it will be better than the first layout...

less stable? it was more planted than a stephen hawkins arse. just found it inconsistent in the corners.

im not sold on the speedo behind the motor, i think it needs to be up front.

Either way, i think the new chassis will be a whole lot better

rcpower · #17 19-05-2014

I drove the 2wd today, with my old home made conversion: motor in the back, esc in front of motor, servo on the other side and a shorty lipo parallel with the motor. The car was just ballistic!!!

Here's mine

As a new convert to the 104 (not raced it at all yet) I am itching to see how it goes, I have the Evo chassis and saddles as far back as they can go, pink springs on the rear and kit anti-roll bars f/r. Maybe there aren't any top drivers using them but I love the build quality and scaled-down 1/8th design. I see from one of the other sites that some people run a centre diff as per most 1/8th buggies and would be interested to hear if anyone in the UK has tried that? Interesting to see the 2wd conversions, I don't think I will be going down that route yet - unless I buy a second one..!
