Tire Hop

[Rc EnthuSiasTs]

After trying to do some reading and find out what causes tire hop, i could not find anything to answer my question. I have a sw2 chassis, 12.5 in weelbase, center clearance at 3or 3.5 inches. I just noticed that my truck starts to hop kind of badwhen it gets stuck. I cant figure out what i need to do to stop this hopping from happening. Any help is appreciated, hopefully i gave enough info on my setup. Thanks!

I don't really think there is much you can do besides run a heavier oil.

Do you have vent holes in your rims?

Tires are a big facter some tires load up and hop bad others not so much.

 

[Rc EnthuSiasTs]

yes i do have vent holes,
that reminds me, i am running stampede wheels right now, they really suck, they have no side wall tread and the are really hard.
I need to get mashers.
Thanks for the info, i thought it wuld probably be the way my links are set up.;-)

I've never seen a WHEEL with sidewall tread. I'd rather have a WHEEL that is hard,I figure a soft WHEEL would be weak.





Oh yeah,you need to get a Mamba Max ESC to"thumbsup"

Wheel hop in a stuck situation is the rotational force of the tires and grip of the tread. Your getting enough traction for the tire to grab, but not enough for it to hold. Add that to a spinning tire the grip will make it want to jump or hop. more weight on the wheel or better gripping tires will help.

what tires are you running

Probly a little,but a properly set up shock with a better link configuration is a better answer.;-)

 

[Rc EnthuSiasTs]

sorry raprotman, i ment tires, i think you new that
I thought it may have to do with the links or the suspension, right now my shocks are stood up quite a bit, should i make them more horizontal?
I dont know how to get more weight on my wheels, unless i put tire wieghts on the wheels.

Naah,I thought you meant wheels.....seriously........:lol:

Make shocks more horizontal??????yeah,thats the ticket.....No,if anything that'll make things worse. Thicker oil might help along with stiffer springs.

With different link configurations,you can make weight transfer differently when you apply throttle in foward or reverse,depending on what you want. Honestly,I'm not real slick with figuring it out myself. I've seen it done though. When I set mine up,I try to keep the links flat with the ground(or as close as I can) and triangulate the uppers and lowers. Theres some debate about verticle separation. Some guys like the same at both ends some like less at the chassis. Myself,I run a hair less at the chassis. So far I've been pretty pleased with my set up. I've tried a few different styles of link set ups and have played with the different ways to mount the links. It's taught me a little on how different set ups work well for certain things.

When the links are closer together at the chassis like raptorman likes it won't squat as much when climbing a hill. It also helps reduce torque twist imo.

I have never had any wheel hop and mine are dead parallel..the closer the arms teh more the axle has a pendulum acton on the end of the arms. this action causes tires to skip

I didn't mention whell hop once in that post.:roll:

What do you mean pendulum action?
Link length have more to do with the axle arched path than location.

A pendulum has a pivot point. The closer the links are together,vertically,makes it more like a pendulum."thumbsup"

More or less verticle seperation can change the value of squat/anti squat you have. I tried once mounting my links at the chassis side on the same plain,vertically. Now that I've got them with a little separation,it works much better.;-)

Link length have more to do with the axle arched path than location.

Nope. Link length AND mounting points have an effect on the path of the axle. Link length and mounting points also effect,hell,they effect every aspect of the way the suspension works."thumbsup" :lol:

That's what I was saying the closer they are the more anti squat you have. The further away from each other the less anti squat."thumbsup"

I said link lenth had MORE to do with axle path. Not that it was the only thing afecting it.;-)

if the arms are parallel then they move in the same motion,

if th arms are close together they act as one on each side and move as one.

You've got too much anti squat.

Simple as that.

thats crazy talk. you dont know squat. j/k.

hey Rc Enthus. describe your "stuck wheel" to us. what is it stuck in?

The actual phrase "wheel hop" refers to what the inner tire does as a locked axle is driven a circle.

What wheel hops? front or rear? are you going up hill? or climbing and object on flat ground.

Wheel hop is also a term used when you try to climb an obsticle,the truck won't go and the wheels "hop" around like they are on steriods.:lol:

 

[Rc EnthuSiasTs]

yes, my wheels are hopping when i am going up hill, when i said they wwere stuck, i ment that i was giving it throttle but it was not going anywere, it wanted to get the traction, but it sometimes just hops around. This was shile i was going up hill.
I know this is stupid, but what is anti-squat?
Is it how much the suspension can unload?
And what is droop? is it like sag?
Thanks for all the help, and for taking the time to answer my noobish questions!!
Oh yeah, raptorman, i thought you were giving me a hard time about the tire and wheel thing!:lol:
