It is normal that the car is allot harder to drive with a one way!
You might want to change the car set-up and the tire setup to make the car more forgiving to drive... Once you get it right, it will be faster in most cases.
The only time I would use a spool/diff is when traction is really high or really low!
You could try softer rear springs, more caster and anti squat, this will make the car more forgiving from the midle of the turn and out! You could also download my set-up from the Hpi Europe site, it works really good on all tracks I have been to so far, even in wet conditions it was great! (just change tires)

Good luck,

Thanks Eirik I have downloaded your setup and I will test it out on Wednesday. Would a slipping rear diff cause the car to be really loose with a spool at the front? Also how long are tires good for .. I was using 22's that had done 20+ runs I guess? Think the track might have been too hot as well would this cause sliding?

Also are you using anti-roll bars front and rear?

Do you know where to get the Excel camber link graphite supports?

Thanks for all your help!!!!

Hello Acutts,

A slipping rear diff will actually do the opposite, less steering!!

How long the tires are good for depends on how much the surface wear on the tires, temperature and compound.

In cold weather I guess the CS22 will be good for about 5runs, in warmer conditions they will only be good for one run etc.
In really hot conditions they will not work at all, the car will be sliding around.....

I use roll bars front and rear most of the time, but you can remove the rear one and at the same time move the rear shock out on the tower. This will make the car more forgiving to drive as it will give the feeling of more rear traction!

I ordered the Excel parts here: http://shopping.rcmodel.hk/

If you try to force more camber to the tires with your hand, you will see how much it flexes. This really made a difference at my local track!!

No problem mate, just let me know if there is anything else!!

how you do you all achieve your setups using swaybars?

do you leave them on the car and setup your car or take them off and put them back on when you have found the correct spring setting?

and what type of setups are used for carpet?
our track has a long straight and gets technical in the infield.
front stiff/rear soft, front soft/ rear hard...etc...

i'm still learning about cars setups and handling so any help would be appreciated.

Thanks in advance!

I adjusted every thing that has to do with roll center by .5mm.

Cool they seem to be out of stock but I will order and hopefully they will get some more in ...!

I was wondering from your setup you use a Mazda 6 shell ... I have HPI Stratus Aero shells ... is this no good if I use your setup ... I can make new shell if I have to.

Thanks again

I still pretty new to the Pro 4 car, but not setup, but I ran the stock (1.8mm I think?) front sway bar and none on rear. It felt good on the carpet. This was with a Assoc. copper rear spring (25 lbs.), 3 hole pistion and 50 wt. oil. In the front a Assoc. Purple (30 lbs.) front spring, 2 hole 1.1 (#3) pistion and 60 wt. oil. (Sorry about the Associated springs, just the only ones I have heavy enough )

Check out the back of the manual for the tuning options. Pay very close attention to how your car has traction entering and leaving the corners and adjust according to that. No need to settle for a bad handling car. If you can't figure it out, ask!!! Everyone here is willing to help

Tires depend on your carpet. A good startin point is Plaid (Purple/Orange) front tires, and Purple or Pink rear.


take care

Hi
Now i've got the PRO4 for a few weeks and I tried so many times to make the transmission system work as free as possible. Do you have any technic to make it run free and smooth?

box stock...the drive train is very free already... no real need to upgrade to more expensive bearings.

TeamPRP

as Zombies has stated, out of the box the drive train should be very free and smooth. I built my per kit instructions and it spun very free. Although I think I did remove one of the large shims but I can not recall which one. My car has been taken apart for months as I've been working on my HTS chassis kit

Hello again acutts,

I am sure they will get more inn soon....

Anyway, the Mazda 6 body is really good, great traction, good steering, great straight line speed, it makes the car handle really well...!
The Aero 2 is really good also, I have never tried it, but from what I have heard it is really good!

My set up works really good with the PF Stratus also, so it should work with the Hpi body also, just give it a try!
