Could be the new pod, I haven't weighed it yet for comparison. Might be the body as well, I use the thicker protoform or parma body, the thin ones break to easily.
I never ran any stock class, but are the motors the same weight as in the mod motors? In brushed the stock motors are lighter than mod, so could be for brushless... anyone tried this???

What electronics are you using, can you post a picture of you chassis layout?

Check your tires, make sure they're the same size left to right.
check for a colasped front spring.

What EricF said... and also check the motor wires. This goes for any car but once you set the tweak you should put the body on and check again to make sure the body isn't rubbing any wires and causing a tweak that you wouldn't find without the body on.

I have seen a few BMI's that don't level out the pod perfectly on their own. Not sure why. Even with the motor wires disconnected and all the pivots working freely, there was a slight tweak when put on a tweak station. The wonderful thing is that although the board said it tweaked, they all drove perfectly on the track.


And on the previous question... My DB12R with 9650 servo, LRP esc, Novak 13.5, pt, lightweight Parma body, a handful of aluminum screws and HUGE JR receiver came to 870g. I have since put in a spiffy new KO 2.4ghz receiver which should put me right around the 865g mark.

The lightweight body makes a difference in weight!!
Also it is almost impossible to have a car with absolutely no tweak at all. When you measure tweak the table and tweak station need to be perfectly balanced and since we do the balancing it can't be done 100%. Also running mod with the DB12R and now the RR I never had a problem with tweak, I just hammer on the throttle at the start and the car goes straight

Inches!
Centimeters would make it a very short shock

Sorry for the delayed reaction. Yes, that measurement is in inches.

Hey Jason,

The changes I made to the car worked great. Knocked .5 sec off my avg lap times! If I could only pull my head outta my @$$ and drive better. Oh well.

Here's the set up I ran.

FRONT
.020 linear springs
#2 Shurlube on the kingpins
10 degree blocks with 4 degree static caster
Jaco Lilac tires trued to 1.65
4.5 mm ride height

REAR
Standard flex plates, long mount
Silva shock, 40w associated oil, blue spring
#3 Shurlube in damper tubes
Jaco Pink tires trued to 1.75
4.5 mm ride height

BATTERIES
EnerG 4600 NiMh to rearmost position

BODY
Protoform Speed 12B
I'm surprised I actually got 3 weeks out of this body!

Car turned in very fast, but the back end stayed put. Shot outta the corners with ease, and no high speed drift thru the sweeping turns.Tire wear was excellent. Hardly look like I ran them. Gonna try 5 degree blocks, and drop down to 4mm ride height, just to see what happens.
