XRAY - Model racing cars

I found that the "basic setting" as well as some team driver's setting have balancing weight on the battery side. I run with IB4200 cells, and with my FK05, T2, and now T2'007, I always found that the battery side are heavier then my electronics side (checked using the HUDY simple tool). I wonder what kind of battery are the basic setting refering to (I guess some batteries are lighter)? Or I did something wrong when measureing the balance? Basically my car will lean towards the electronic side unless i put some weight on the electronic side...

Also, does anyone actually balance the weight front and rear? If so, how do you check? by mid-point you mean the mid point (front and rear) of the chassis plate? Or the mid point including the front bumper assembly? Or just the mid point between the two wheel axles (front and rear)?

Lower motor temp is always better for the efficienty (how do you spell it??) and life time!
