a friend of mine has his R2... and you just THINK of turning and the car makes a u-turn.. thats how twitchy it is. i dont want it like that.. be something inbetween his and mine.

might as well put groceries in mine and call it a shopping cart. it pushes that bad now if i could only find a way to put the R3 drivetrain with the EvoIII suspension

that is the problem I have also you have to start turning the thing down the straight away to make it around the corner
and on a tight carpet track this steering isnt helping at all!

If some one with a R3 has solved this problem please share the info

Have you guys tried the mid span arms on the R3?
thought they were supposed to give a more responsive feel on high grip surfaces.

dannnng. no luck with the hpi pistons. i had someone else drive my car... and they said it still pushes. i thought i was getting somewhere. here's the set up....

Front and Back
5mm ride height
5.75 springs (i used 6 and 6.25 all around, there's a difference, but not much)
40 wt oil
Hpi #2 pistons
Droop: 7mm (chassis flat on a setting board, measured from the end of the arm)
-1 camber all around
no sway bars
roll center raised 3mm
shortest camber link for both F & R

=======

Front:
0 - toe
middle hole for shocks(5 holes for the R3)
inner hole on the A-arm

Rear:
2.5 toe
2nd hole counting from the inside for shocks
3rd hole counting from the inside on the A-arm

at socal, i ran Pit 30s with Xenon Blue inserts and Sorex 36R with HPI Greens...

ran the following bodies:
Mazda - good steering, not very responsive
Bugatti - more downforce a bit more steering.
Alfa - rear end is loose mid corner and on power.

GUYS... the drivetrain is about as free and smooth as I can get it. people who have seen it are impressed by it... (without ceramics, i have a free spin of 7-10 seconds). im getting very discouraged here.. not getting the car to where i want.

please PM or email me with any suggestions..... if im doing something wrong, pls let me know...

Linger... i still have to try your ideas. thanks for reading.
if u want more turn in, here are some things u can try..

less caster
more front toe out (+0,5)
less rear toe in (-2,0)
rear swaybar

I have some Trinity red dot tire sauce you can put on the front tires. That will cure any push.

sounds like you need to try somthing radical, my R2
Yours for just $450

How about putting any ballast on the front bumper?
You could always fly me out there and I'll drive it for you, I like cars with a bit of push

AWOL... just easier to get more steering with the Evo, SD's... Losi if i remember correctly. that might be the chassis? but this is the first time ive struggled to find steering. of all the cars ive had.. this one has given me the hardest time.

im not giving up on it YET because my drivetrain is sooooooo free right now.
Just so you know, those green inserts had 3mm cut out of them. Gives the tire more air gap which will help them heat up faster, but if you run them on a very hot surface (like we get in the summertime outdoors) they will most likely overheat and get loose 3-4 mins in the race.

Also take the washers out from under the rear inner camber links, run the losi alfa body and just figure out a setup for that, dont switch bodies, because those make the car handle very different.

Let me run a pack through the car, I'll find the setup, it took us a while in the R2, but now I know what to go after...

R3 Guys,

Try moving the ball stud on the steering knuckle to the foward hole. That should give you a lot more steering throw than the kit position, and give the car a tighter radius on the turning.

So Chris are you ready to sell the car?? JK I was gonna get one but im getting discouraged. How do you compare this car to your old R2? Other than the understeering. I bet they come out with a different chassis for the R3 soon.

the car doesnt understeer dude. its my set up thats all wrong.

if i were you tho.. id get one. im not sure if you've seen the drivetrain on my R3.. but its 10x more free than the R2.

alex and steve bought taught me how to free it up.. and i used the same technique on both cars..and the R3 was wayyyy easier to align and free up.

once i get the right set up.. oh my goodness! its showtime!

the chassis on the R3 is a lot stiffer too.. even tho its only 2.5mm. its as stiff as my old xenon stage 2 R2.

oh ya.. get a pink one! hahahha

Ran my R3 last night for the first time, and I was extremely pleased. First time racing in just under a year, I qualified 2nd and finished second. Was on a tq run both qualifiers, and I screwed it up, but the car was all there, it just needed a little better driver.
