It seems there are two different cars on the market under the name S120. The difference is pretty big between the two: the servo positioning is different, one fits with Futaba and KO servos, one does not. Also one kit has got 3 and 9 degree caster blocks the other has not. The rear axle is also different. The T-plate is different. I think it is pretty difficult to know what kit you will receive if you order the car.
Regarding the servo position: it is clear that there are at least two different servo mounting sizes on the market. Serpent now changed the hole position to fit for Futaba. I think they should have left the hole where it was and should give two different servo mounts with the kit or give one servo mount which is adjustable.
However, I still think it is a good car.

Practically these are only 2 different combos, two for left and two for right, but in reality it gives only 1 for left and 1 for right as you can not mix the post of left and right.

hey, i am using the exact same servo. and it looks like if you try the other block with the hole in the OTHER side it will work.

hi
we have bought 3 kits of the new badge S120
and already have some problems

like said in previous posts, the king-pins
even with asso balls in the lower arm the king pins are not going in them
i have dremeled the KP to 3,06 in combination with asso balls and seems to work perfectly now

in one kit there is a problem with the alu rear pod
on the left side (where you put in the ride height spacer) the hole is a litlle oval and the ride height spacer can not fit in it, i'm talking about 1 mm, but for a kit like this, it's imposible to get this in your hands
horizontal is 22,30 mm
vertical is 21,75

looks like the pod have had a crash in the factory

the pivot ball mounts (plastic) on the T-bars with the poor 2 screw mount is not preciese, and in combination with the T-bars design for mounting this, the T-bar is more breakeble than any other tbar, why they didn'd choose for an asso (4 screw) disign here?

for the servo mounts, i'm still building, but i have only KO 949 and 951 servo's, so i hope that they are centered

overall the car looks great
but i'm curious what's it gonna be at the track

at this moment i'm driving hotbodies cars, they haven't got that look, but they never let me down in a race

i hope i can exept the same from serpent

sorry for broken english
grtz

I see most of you guys are mounting your servo at an angle, what is the difference if you mount it flat on the chassis?

the mounting post create the angle, there is no way to change it. my mental geometry engine can't predict the effect but the ackerman would somehow be effected.

Think the angled mounting is better for bumpy ashpalt tracks and flat mounting better for carpet ?

avs, the way I mounted my servo is without the servo mounts. My servo has ears on the side that allow you to mount it virticle or horizontal. To get more or less ackerman I slide the servo up or back depending on what I'm looking to do. I will take a picture and post it later.

You can mix the posts. As they have offset holes you can use:

2 with holes offset left
2 with holes offset right
1 right one left
1 left one right.

They will give 4 different width between posts and 2 different positions of the servo related to the centerline.
Combined with the fact that you can make the post more narrow (although I agree that shouldn't really be needed) must create one set that gets things pretty close.

The drawback of mounting the servo on the chassis is bump steer.
you'll need to put spacers between the steering arm and the ball to get the steering links to at least a horizontal position.
