Lowering the centre of gravity.......
Been thinking about this one for a while....
Want to be able to achieve the following
1) Stop the car from flipping on carpet.
2) Get better handling on floorboards.
3) Get some drifting happening, if possible.
So I started stuffing around with some lead and I bashed a ball of it down into a plate of about 1.5mm thick. I then cut this plate to match the chassis profile from underneath. After this I then gave the lead multiple coats of clear gloss 'cause lead is poison and it can be absorbed through the skin.

As you can see it ain't much to look at but it fits well. I use some bluetak to secure it to the base of the car. It ain't a perm fix 'cause one needs access to the battery terminals for charging.

One idea though that has come to mind is that the lead helps to magnetically "insulate" the steering assembly from the ground and in my tests I've noticed that less crap gets caught in the steering. One place where I drive my cars has lots of metal filings on the ground that the car will just loose it's steering with 20 seconds. The lead base plate has helped mitigate this.
As for clearance.....No problems there. I guess a full wheel mod would give you more clearance and allow a larger piece of lead to be positioned there....

So here it is, some video of a car with the lead plate. The car is a 45mhz chassis, mosfet mod with the perf 4.2Pro and 12:1 gearing. Rear tyres are lxx softs...
VIDEO (Divx)
One thing I have noticed is a reduced runtime due to the increased load on the motor because of the lead plate. Increased load = increased current drain = decreased battery life.
Generaly I have now noticed better handling on floorboards. It might not seem the case from this video but before any motor above a 3.0 on my floorboards just ended up in torque spins all the time. I will do some more experimentation on this, increase the size of the lead plate, change the distribution of weight, etc, etc.....

Re: Lowering the centre of gravity.......
good idea man, would it do the same with wiht just some alloyminium or something, like the vid u got some good drifts on there and good handeling on the wooden floor, i got a wooden floor to and it is bloody hard to control.
