How about a 1.6?? in rear tire and still get 4mm ride height. Not another 1/12 out there capable of doing that AFAIK.

I think a Serpent with Stormer Bob's conversion would do it. That's about it.

Hey guys,

Last weekend I had some good success with the RR, but had some questions.

The setup is:

Front:
Ride height 3.5 - 4mm
Caster is at One shim in front and one in back on the 5Deg block
Neutral Toe
About 1.5- 2.0 Neg Camber
Laydown Servo so I have some toe in on compression
Fronts trued/worn down to 1.6 or so
.22 linear springs
#3 Sure Lube on the kingpins
Compound - Lilac

Center:
Batteries all the way back.
Center shock at the tall front mount position
50wt in the Siliva shock, gold spring
Sure Lube #3 (Green?) in the tubes.
Thin flex plates with the forward mount in the rear (stiffer)position
Center height 4mm

Rear:
78 Spur/45 Pinion (17.5)
Ride height 4mm
~ 1mm droop, maybe less
running tires trued/worn to 1.7
Compound: CRC Gray-Low

Body Parma Speed 8.


So yesterday we were running out second week on the same layout. So traction was "OK" starting and fairly consistent but it was still low bite for the first race. On that low traction run, my car was fantastic. I set the fastest lap and average laps of the entire day and nearly lapped the entire field (and I am not a great driver!!) The car started to push slightly toward the end but that was fine. the fronts started to push because they fuzzed over.

Then as the qualifiers happened and the main came, the traction went up, and I had an issue with the car starting to traction roll or pick up a rear wheel in corners. So what I did was just didnt coat the fronts with traction compound much (inner 1/3) and the traction rolling went away.

But what I am fighting wiht is by the 8 minute mark I have fuzzed over the fronts and rears by the main. I am looking for any insight in how to avoid the fuzz problem? Is it a driving style thing? or how the grip comes up and how I throw it through the corners?

For the qualifiers after I went down the sheet. My first qualifier kept me high enough to start 2nd in the main, but an electonics issue knocked me back in the (reciever turned off or locked up after driving over a plowdisk).
to 4th I still had fastest average laps of most anyone at the track in 1/12th.. Just lost all traction by the end and couldnt claw back.

Any help?

Fisrst thing i would do is change tires. When the carpet is fuzzing up, the only fronts to run is blacks. This will keep the rear from swinging out on you. The rears will be fine. If you are still lifting an inside rear wheel then you can lighten up on the damper tube lube.

Will the 0-ring work to hold a SMC 1s lipo in the car? Anyone know of a molded bumper that will fit the BMI 12rr (its been a long time since I have raced 12th).

Hi guys,

i have ordered my db12rr.
Now i want to know is, what tools ( wrenches and nutdrivers ) do i need to assemble the car?
I like to assemble it when it arrive.
Which body is the best with the car?
One of my tracks is small and smooth the other one is large and smooth too.
Both medium grip.
Im am with the Blackart r8c and r10.
What do you guys think about them?

You will find a list of needed tools in the manual, which is available also online

Any body will fit just fine, it's a matter of personal preference. Blackart is good. For club racing where bodies are not limited I personally prefer using the Parma Speed 8 HD and Zytek for EFRA regulated events.

one question on servo and trackrod position
Im using my DB12RR quite as build with the manual so servo angled with servosaver showing downwards. Also trackrods in front of the servosaver what means angled also.
Now I saw some pictures where the servo is using a angled mounting also but the trackrods behind the servosaver what means straight trackrods. For this I think the rear holes are used on the servo mounting what means more weight to the front but I think the straight trackrods will affect ackerman and other things also.
What is the difference on the track between these two versions?

Front:

5 degree block w/ 4 degree castor
.020 linear springs and #4 surlube on the kingpins
3.5mm ride height
servo flat w/ medium ballstuds on the steering blocks
Lilac front tires cut to 1.650
.25mm droop

Rear:
Gold center shock spring
Silva shock w/ 60 wt AE oil
Medium ballstud on shock mount
batteries in the middle
#4 surlube in the tubes
Stock flex plates mounted in short position
no tweak screws
Yellow rear tires cut to 1.750
172mm rear width
1mm pod droop
Pod Level at ride height
3.5mm ride height

Car handled excellent. For higher bite i would go to a red center spring and move the cells all the way forward.
hi Jason, sorry if i missed it, but i have been looking for a current setup for asphalt. what would you suggest for a medium to high bite asphalt track?

Im running a Protoform Speed12 currently on my DB12RR. Also I got a Speed 8HD and a Black Art R8c now but had no time for making them ready to race. I think the Speed12 is what a lot of drivers are using here currently on most cars.

Are you coming to the 1/12 Nationals at Ingolstadt this weekend? I will be there just hope Im not the only BMI driver.

I would go to 10 degree blocks up front w/ 4 degrees of static caster. Go to the angled servo mounting and change the tires to 2x pink front and rear. Maybe 50 wt. oil in the center shock. The rest i would keep the same until you feel out the track
