Curt's Dlux Superlite Berg-ler

[ubbb69]

If you want your throttle profile a lil smoother start with the throttle curve in the esc programming then fine tune with expo. Works great when just expo will not cut it. I can tell you also the br mini are butter on low end.

Good news. Thanks!

But your thread is called superlite?

[Curcal]

The axles are called superlites. Only things berg on this B are the gears. All my weight is in my motors (almost a pound, 6.7oz per motor). These cb20 can mags are very heavy. As I dial this thing in weight will come off too.

[sally1800]

Just playing with you.

Those motors are heavy.

Im open To all suggestions thats what a build thread is for

Ok let me see if I can put this in words. Take off all expo on the radio and set the throttle curve back to default. Set your truck onto a slight incline or flat surface. Either will get you close. Slowly pull your throttle until the truck rolls smooth. For the sake of being easy lets say we use 25%. So as you pull the throttle it gets smooth at 25%. Now go into the esc programming. Bring the throttle curve straight up to the value it is at 25% across the graph. So now your throttle curve will come on at 1% of throttle pull as it did at 25% on stock setting. Try this setting and if it is fairly close use the radio expo to fine tune it. If it is to high or to low go back into esc programming and adjust it accordingly. Once close in the esc program us radio expo to fine tune.

Not shure if anyone can follow my rumblings. If not I will try to explain it another way. What you are after is the lowest voltage that is smooth to be the lowest setting the motor see's to prevent cogging.

That seems pretty close to what I was doing. Ill get to fine tuning when my minis show up. Thanks for the pointers!

[Curcal]

After a few weeks of running the adjustments made On the esc's and some drive time they have some pretty nice control and gobs and gobs of drag break.
I shortened up the rear shocks using Team Associated unobtainium shock shafts.
My next change will be to gain some squat clearance with some bent upper links.

Let's us see those uppers and how well they work

[Curcal]

After some trail and error in bending Al links. I was able to get my car to really sack out. If I like this ill probably bend up my rear upper links.

[Erik D_lux]

Crazy! I like it!

I have always been cautious of doing bent links myself though. I think you can change the squat/anti squat simply by putting a bend in a link.

[Curcal]

It would make sense that the link applies pressure a little differently with the bends over the straight. For the most part, while I was testing yesterday I couldn't tell the difference. I would love it if I got a little more squat an pressure on the front axle with the bent links, but my gut is telling me if it made a change at all it was less down pressure.

When I get a chance, probably this Tuesday I'll run the course once with the bent fronts and once with them straight and really get a comparison. With the extra 1/2 to 3/4 inch down travel at the chassis it helped with some of the sidehill ability.

I also need to double check that my WB stays within 12.5 as it does the full travel

Nope. Even with toy cars, the laws of physics still apply.

It would be cool to hear your theory or results. Even something to read online? All I have ever found only concentrates on straight links.

Erik, it has to do with the vector of the force applied at each mounting point. Those vectors (direction and magnitude) point toward one another and do not follow the contour of the link. Those vectors can be broken down into different parts depending on the coordinate system.

Imagine one of those crazy straws, the liquid still goes from your cup to your mouth. Same as a straight straw. Two points lie on a line, independent of how you get there.

Hey Jeremy, miss you sweet thang.

No need to mess up Curts thread. Here is a new one in Gen

Does a bend in a link effect the geometry of the suspension?

Don't you have to apply more force (suction) on the straw with all the crazy bends to get the liquid to travel from point A to point B? Although that could be more of a liquid dynamics issue....

Good Tech talk is always welcome on my thread!

BTW: How can you quote more than one post into a new response?
