Chassis weight theory

[Chris_The_Battery_Man]

Got my truck all ready for the comp tomorrow. Added 2oz. of weight to the chassis on either side with 2, 1oz lead fishing balls. We will see how she does. If I have spare time, I might try putting the weight on the back of the chassis to see how it effects the way it drives.

The thread is a bit derailed, but I'm still following you with great interests

I`m having problems understanding the point of this experiment, without comparing against other weight distributions/loactions on the same criterias/line`s ?

I think this is a good experiment and i hope it gets more attention. I was into trying to get my XR light and was running .063 chassis plates and plastic scx10 shocks. I bent the chassis the day before a comp. So i threw the stock XR chassis and shocks on plus 1oz on all 4 wheels. It added 5oz to the chassis and i feel it works much better. My rig is sitting at 5lb 8oz rtr.

So i think your theory is correct because it is what i have noticed with my rig since switching chassis's. It feels much more planted on climbs, decents, and even side hills. And i am not saying just a little, i am talking night and day better.

Well, I have to say that my truck drove quite nicely. I wouldn't say that she is perfect. Could use a free day on the rocks to tune her in. But I didn't notice any ill effects from the chassis weight. I may hit the rocks this Saturday to get some video and more testing done

Very interesting read with lot's Idea's. Would this also work for scale crawler's? I ask because adding wieght to the front tires obviously helps but how much is to much wieght for a crawler or scale rig. I like the idea here, be interesting to see what happens

I have been following this thread since it started.

As far as scalers go weight is important depending on the design if your truck and style.

I run generally tube style trucks built by DMG. Im one of those firm believers that a heavier truck can perform well if its set up right. With help from war pig and focused I have narrowed down the path white a bit with very little roll over.

Comparing lines that you would take with a 1:1 to a scale crawler is a bit different. Were more likely to take steeper lines then we would if we were really behind the wheel.

The only true way is to test because each rig will perform differently.

i like the chassis as light as possible








rtr weight is 1830 gramm , chassis with panels and receiver is ~80 gramm

max belly clearance 110-115 mm , max clearance under the rear lowers highest point 140-145mm

I was refering to his post where he might got time to move the weights.. So no, i didnt take it obvious that this was the intention for this days experience/experiment.

Amazingly I to have found the lighter I go the better my truck works. I would imagine there is a point were it will start to work against me but I'm not there yet.

My current Sporty rig RTR is 4.10, with a very low COG thanks in part to knuckle weights, beef tubes, a very stock Axial transmission and a light weight bodiless chassis.
