X6 under steer !!
 

Hi again guys who can advise best for under steer !!
My x6 doesn't seem to take corners all that well , yes I'm from far the best driver however I'm sure this is contributing to my downfall .
A very good driver at my club drove it and said its under steering bad and that I need to look at the front end .. However that's as far as he got so can any 1 point me in the right direction ??

Cheers Craig

Look at the setups on PetitRC for a surface similar to the one you are running on and give that a whirl.

Will be much easier for people to help if you post your current setup and a description of the surface you are running on too :lol:

Fit the E Speed hangers if you havent got them on already.

Also make sure your servo saver isn't unloading (tighten the spring if it is). If you have a decent metal geared servo, you can look to gluing the servo saver together or fitting one of the many 3rd party alloy steering bellcranks that exists (Jconcepts and Avid do them I believe, others exist too).

But we really need to know your setup and what your track is like to offer any specifics...

what servo do you run, whats its torque?

Are you getting full lock to lock travel in your steering? I've seen some B4/X6's setup that were not reaching full travel on their steering and had to zeroise the servo (horn) position, re-adjust the link, and reset end points and travel over 100% on the tranny. I've also seen an X6's chassis around the servo horn fouling and limiting travel in one direction. A dremel will sort.
As mentioned the servo saver spring can be weak and reduce responsiveness of steering. Fixed is the way to go, but you may break a cheap servo's gearset.
Other than that post a photo of your front end, or list the settings you have.

Almost every time we hear of an X - 6 that understeers badly going into a corner it's the servo saver. Most AE Team drivers, and all X-Team drivers lock up the servo saver, often with glue.

As stated above, you can't use a cheap servo with this, but since most Family members are pretty serious about racing, that's not an issue.

Thanks for the replies guys !! I think it'l b easier if I sum how uPload a pic of the car / front end as everything mentioned from u guys is a bit gobble de gook ! I'm new to Rc so I'm sort of learning as I go with things . Wil upload ASAP

Just remember that the front end is only part of the equation. Do you have the setup manual and starter sheets from the x6? The setup sheets are just a way of recording how the various options are configured/set. The wording at the back of the x6 manual will help you understand how some of the settings work.

A picture will help us gauge if anything is majorly wrong.

The e-speed hangers provide different camber link positions on the rear; as a beginner I doubt that not having these will be the problem.

I would check that you are getting full steering lock both ways, that nothing is loose and that you are running tyres suitable or the surface you are running on.

It's difficult to suggest further until we know the above is checked, that your servo saver is tight, we have your basic setup and know what surface you are running on.

You've got a great car to learn the ropes with though!

DOES THIS HELP AT ALL ! !
Our club Is Caldicot Racers and we pretty much run on Carpet & shinny floor..
Looking at the Servo it has the letter HPI SF1 on it ???
the motor is Thunder tiger? possibly not 100 percent tho

All opinions welcme :cry::cry:

You have the e-speed hangers (they're the blue alloy parts that the inner rear camber link connects to).

What surface are you running on? I would definitely check your servo saver, is it too loose. What servo are you running? find the b4 manual online if you don't have one, or the x6 manual, and look at how to set the servo saver.

to be honnest your servo is not up to the job, its too weak,


Discontinued at HPI Europe, replacement part 104105
The SF-1 servo is useful for electric touring car steering duties, nitro car/truck throttle and brake, and other applications that don't require large amounts of torque or fast speeds. It's perfect for the Savage Reverse Module and Reverse Mixer Pro!

Thanks Mark ! ! ! A starting point .......

As i said earlier im new only been racing about 8 times and i know my driving ability might not b up to scratch but i just wanna giv myself every chance ,

does the car look alrite in any other way though ? just incase theres something else that could help me towards racing greatness :lol::lol::lol::lol:

Don't know the guy but something like this savox would be perfect

Thanks tobys ! been very helpful .....
Can u see anything else that could need looking at ? my understanding is my setup pretty basic????? i bought it RTR second hand so its stil as i Brought it .....

Once you've got a servo that is strong enough to turn the wheels properly and you've checked your servo saver, just keep driving! Practice, practice, practice!

Keep you eyes on the for sale section when decide you want new batts, motor, speedo etc. you can get some good bargains!

Don't be afraid to come on here and ask detailed questions; the more info you can provide the easier and quicker it'll be answered.

Let us know how you get on in the future :thumbsup:

Sometimes I feel an idiot though asking such Mundain questions tho its a nightmare .... but im glad there are people like u who are willing to offer advice

thanks very much

Move the bottom of the front shocks in, it'll soften the suspension and help with front grip.
What ride height do you set it at? Do you know what oils are in the shocks?
I set my car to the Ellis Stafford setup up the X factory website and the only thing I've really changed has been the rear shocks which now have 40 oil and number 3 pistons.

dont feel daft we were all in your position at some point!

as has been said upgrade your servo, and practice, car looks ok , if you look you will find some set ups for the car on here/xfactory site, the car is still a good performing car and bits are easy to get thanks to its associated front end and DMS can supply just about any model shop spares or you can buy direct.

Hi phil , Not sure on the height as its been altered by people at my club recently in order for the track on that night ...

about 3 weeks ago i replaced the shock oil that was in there with associated oil front and back ... 40 & 30 weight ..

cheers guys :woot:

From the pics the set up looks ok.

If when you sort the servo you still don't have enough steering make the front link longer on the tower, I always run this with stagger ribs. Also they look like AE blue front springs, if so they are really too hard, get some silver AE fronts and give them a go.

E

Thanks Big E .. To b honest i only run whatever has been advised by the rest of the drivers ... blue springs on the front and silver back i also drive with cut stagger ribs , again on advice see

Are they the same front tyres that the fast guys use?

This is the setup I copied as closely as possible making small changes to suit me the more I drove the car.
You could try a less grippy rear tyre to prevent the under steer but be careful, oversteer is worse, under steer can be recovered by easing off the throttle, oversteer can end up with you facing in the wrong direction!

yes pretty much all the club tends to use cut staggers .... orginally i had mini spikes on the rear but changed onto mini pins

That looks like an original X - 6!

I very much suggest Ellis' starting set-up. Most U.K. racers begin there and, as has been said, it seems to be very close at most tracks. Big E won a couple of National championships with it, so it's probably pretty good...

On our web site are a large number of set-ups, including Ellis'. Also a down-loadable set-up sheet. If you are going to use one of the suggested ones, please do all of it just as it is written. It simply won't work well if you leave things out. This includes tires. When you see anyone's set-up sheet, remember that set-up worked for that driver on that day at that track. The same driver at the same track on a different day will likely use a somewhat different set-up. Confusing, isn't it.

Start with Big E's standard -- print it out if it didn't come with your car. Then print out several of the blank sheets and, as you make changes, make a new sheet noting the changes. This will help you remember what you did and especially what your changes did to the car so you can either duplicate that if it was good or not make the same mistake again.

Paul lliterally carries around a notebook with every change he makes at every race. Ellis uses his laptop...
