Probably due to inconsistent durability of the balls (a common problem with non-certified ceramic bearings).

lunytune if you need a souce for certified ceramic bearings (for only $1 per ball) email and I'll send full info. We've been buying the certified grade three silicon nitride diff & thrust ball sizes in bulk for about five years now. JRX-S Bill and a few of the other rctech members have been using them (in fact Bill just posted another recommendation in the forum today---thanks Bill!)

Default Difference

Does anyone have a solution for the weight difference a battery puts on the chassis fully loaded. Battery side sits 1.5mm lower then the electronic side...... Maybe chassis weights just do not know how much and where to place??????

Set your ride height first and then check the spacing of the collars on the shocks. If they are way out of range from each other then maybe the chassis has a slight tweak in it. Take the wheels off and the shocks and put the chassis on something that you know is flat. The loosen the top deck and position the chassis and then tighten down the top deck.

Other things to check:
Make sure your shocks are equal length.
Measure your spring length to make sure they are equal.
Try a different set of springs as well.
Make sure the bottom spring retainers are seated properly on the end of the shock shaft.

Hopefully it is something really easy to see but at least this should help get you going in the right direction.

anywhere between 84-100grams usually will balance it out.
Depends on your layout.
about 21-28 grams next to your motor on the outside part of chassis.
about 14 grams in between your main shaft and your esc
another 14-28 grams next to your reciver on the outside part of the chassis.
I put 7-14 grams between my motor and my esc.
Don't stack weight. Distribute it evenly on the electrics side.
Again, this all depends on your layout, but if you stick to around 84-100 grams you should be close.

any hobby store has them.
They are "lead chassis weights"
Small hunks of lead that look like chicklets gum.
HPI makes some niffty looking brass ones that you need to screw down, but weights are weights.
1/4th of an ounce equals about 7 grams.

At any hobby shop or golf store. It is lead tape that has an adhesive side.
