Why do our 1/10 Crawlers with 2.2 wheels Roll Over without Hex-Wideners?

[Jjay]

I feel like a Newbie now also my old friend.
So i ask this here.

We have Crawlers scale 1/10.
I have 4 and 2 build going on ( six total soon )
My old RC Friend lives far away today. He moved far because new wife.
Anyways he does do RC still. And he got now 2 Crawler, third on the way.

He got one modified Vanquish and also one Losi Comp
Both with 2.2 Proline

I have Axial and couple other brands. 2.2 Prolines too.

One thing is similiar to both me and my Friend.

All our rigs Roll over easy when climbing sideways if we dont use 10mm - 15mm wideners.
Then they are OK.

With 25mm wideners all rigs are fine.

Our cars have about 15mm more Ground Clearance because the huge
2.2 tires. They are more top heavy.

Anyways, how are the new TRX4 High lift crawlers? Do they roll over easy too? Or do they have special Low center chassis?

We have found out Huge Wideners is a must if you go big 2.2 wheels.

Soon i will also have extra weight in my wheels.
60g + each front wheel, 30g+ rear to help have more weight to the ground.

Narrow crawlers is not good we have found out.
Sometimes Narrow is good, if you need climb between two big stones close to each others.
Anyways
Now we use 25mm Wideners, and need find wide spots to climb.

Also you can not have Scale body without wideners when using 2.2 wheels.
You must have Comp body, or Wideners.


What to do if you want narrow 2.2 Crawler? Use Comp body also.
You need buy LCG chassis then? or have alot extra weight at wheels?
If you dont want roll over.

?
?

I did order also rims. Extra heavy weight now. These weight about
4x more than normal alu 2.2.

With alot weight you can not drive fast at trails anymore i know.

And you need go down maybe 1-2 tooth on the Pinion also?


We want only 2.2 wheels, big tires, alot Ground Clearence.

Help

Because you didn't get wider axles
For 2.2s you want ar60s or bigger

3 words, center of gravity. With a taller 2.2”
Wheel and tire the center of gravity is taller. Therefore making it more too heavy and flipping over more often. You need to widen the stance and/or a ton of weight to offset it. The price you pay for having a little more ground clearance

In the 1to1 world they say for every inch of lift you need a 1/2 inch extra in width so 3" lift is 1.5" wider than stock

I Have seen people who install high lift in 1/1 real jeeps, they always
buy spacers, or aftermarked wheels with different offset.
So it is true when i think about it now.


Thank you guys
Then i know now, always if you go with tall 2.2 tires, then you always
need mod the Crawler to be wider also.

Best with wider axles like ar60s
Second choise Hex wideners. The cheap cheat way

If you want narrow Crawler use smal stock size 1.9 wheels

I will tell this to my friend also.

And it is because the Center Gravitity change

Thanks

Build it low, build it wide...AR60's ftw...
