Get a 5000mah 40c battery.. About 300 grams worth of batteries.
Make slugs to fit the battery holes in the chassis.
Glue them to the battery. They will also help keep the pack in place.
I highly recomend brass. But tungsten is heavier. You are going to need approximately 110 grams to get it up to weight depending on what electronics you are using. Try to keep the bottom of the chassis smooth and the weight low.

Your friend would be correct. This is the exact same findings I found when I did a back to back test. It gets pretty hot out here at times and that extra 20 degrees helps the motor. True you could gear up but if you're not hurting for power or top end speed why gear up?

what i do to balance my car is... i weigh all my electronics... then weigh my battery. i add weight to the side that is lighter.

then i distribute the remaining weight i need to add evenly around the car.

so for example.. if im 28grams short.. ill take 4 pieces of lead weight that is 7grams each.. put two in the rear...two in the front.

also, if your battery is significantly lighter than your electronics side... try getting this:

there are two small areas you need to dremel (for the motor mount brace and servo holder)...and it fits like a glove underneath your battery.

I've been running the LRP stock spec 10.5, which is pretty torquey but doesn't have the RPM of the novak, so I normally find myself quickest when geared up as it has the torque to pull through the infield with a tall ratio. I believe my novak and spx speedo arrived so I'll be gearing right down, and if I can achieve similar top end without having to cop the weight of the fan on the ESC side I'll be

I finally got the 416 dialed in, the car handles amazing!!! In the final this weekend I was doing really good but half way through the race I noticed the car handling weird earlier in the day the Steering post screw backed out and was not letting the car to compress, I fixed that and lock-tighted all the other bottom screws. but in the final "3" top deck screws in the rear section almost backed all the way out. I'm a pretty strong guy and sometimes over tighten screws, I think with the added flex it caused the screws to work its way loose. I've since put loc-tite on all the screws on the car(blue loc-tite) so this never happens again. can't wait till next race and drive the car again

Do other people have issues with the steering alignment going out in even small bumps? Whenever I tag a barrier, I often have to give my trim a couple of clicks to get the car to go straight again. I thought it might have been the servo saver so switched to the square alloy insert, so now its either the servo or radio, or it's the ackerman screws bending slightly
