They changed things up a bit this week. Just when you thought a track couldnt get any more technical, they exploit ALL your weaknesses!
1. Poor reaction time...check
2. Poor hand / eye coordination...check
3. Lack of natural driving ability...check
Fought the first heat race with the front end hopping in the turns, added some weight to balance car and ran great in the second race. Got loose in the third, then traction rolling and broke in the main! Never a dull moment in VTA!

Club racing tomorrow. That just became our track design of the day. Should be fun. Got the X back together after its hiatus. Running the newer 10mm shocks , the 0/4 R pivot support and trying out a spool for the first time. I'll definitely keep notes in the hopes someone can use them. There's not alot of concrete setups available for the xxxs.

racing tomorrow as well - if - the rain stops as planned. Going to try the set up suggestions from a few posts back. I plan on getting to the track early to get in some good testing before qualifying.

I was going to flash my speedo with v203, but I don't want to add any more changes until I work out the handling. I'll save the extra speed for later.

What diff set up do you guys run in the rear

i used too run the standard xxxs set up then came across the B fast unit (it's for a XXX4 but fits in no problems)

I found it too be so much smoother an last alot longer between rebuilds

The b fast set up come dead flat along with a captured thrrust bearing

I jus liked the overall feel this gave and it lasts far longer b4 it has by feeling of grittyness
even then it stil feels as good as a normal standard diff

Standard diffs for me also except I do like the captured thrust bearings. Getting hard to find so buy em' while you can.
What exactly is the B Fast unit?? What parts does it consist of?

Still Bill.... What are you running now??

Club racing today and the X was spectacular !! My first experience with a spool and the car handled great on our tight, technical track. Again...a surprise because everything I've heard about spools says they're no good for this type of track. I can't take the credit though. This was basically John Chen's concrete track setup as posted on the Losi Board. I'll post the whole thing later but the unique features of this setup are the high roll centers front and back. In addition I used the 0/4R support in the front and the car now has Losi 10mm shocks with very soft springs. The spring rate is a guess as they were some extras I had in my tool box but somewhere around 10 psi would be close. If anything...slightly to soft. If I had to complain I'd say the car had a bit to much roll but not enough to adversely effect handling.
To give you an idea...I had built the car with a spare 21.5 motor and a Havoc ESC to race in our RCGT program. Against other cars with 17.5's and 27t brushed motors...my car was more than a match. Luckily the course was technical so any disadvantage I had in the straights I made up for in the corners. At no time was I unable to beat the other cars in the twisties. She was glued !!
I'm also quite amazed at the overall performance with the spool.

Well I thought I might join in.

Home Track: Hobbyplex- Omaha, NE
Class: VTA -Ozite carpet
Driver: B Mainer
Chassis: RTR
Electronics: GTB-21.5 Novak-2S lipo-Spektrum D3R

Std diffs: Front tight as it will go, rear medium
Front:
caster 4
frt shocks silver -standing up, internal limiters
oil 30wt
longest camber link
medium roll (losi low blocks-still need to sand down the front for a true low)
0R -bottom holes
arms forward
0-1 toe
-2 camber

Rear: 1.5 toe
shocks pink- laid down, internal limiters
30wt
longest camber link
medium roll (losi low)
0R- bottom holes
arms forward
-2 camber
HD black belt
FDR: 5

Fighting drag: just went through the bearings (clean & replaced as needed).
Trying to catch a couple of xrays that pull me just at the end of the straight-a-way. thinking maybe dropping to a rear toe of 1.0 but that seems a little out of the safety zone. Hoping my cleaning will do the trick, will fine out Weds.

Tires are critical in VTA -ran my old set a little too long - lap time drop dramatically and handling went to hell. I'm getting by on another old set while I break a new set in during practice.

Well, pretty good outing today for my X. Both qualifiers were tanked with two crashes that somehow turned off my power switch . Oh well, stuff happens.

Overall I liked the car with the changes I made. The push is gone. The big change there was just taking the spool out. Hmmm, maybe I just don't know how to drive a spool

So I am running the setup I posted earlier, with these changes:

1.) Replaced spool with diff.
2.) Balanced the car side-to-side.
3.) Added 1mm of droop to the rear (5 total)
4.) Moved shocks out one hole to #3.

After changes 1-3 were tested, the car actually seemed a little 'slow' reacting in turns. After the race was over for the day I went out on the empty track and tested something. I made a guess and moved the shocks out one hole to stiffen it slightly. Paid off. Overall the car is not the sharpest handling, but it does not push and is easy to drive for a novice like me.

I also tested some better gearing and I gained some snap outta the corners. I think the suspension changes + the gearing change will be good to beat today's winner next time. I finished a close second to a brand new Cyclone with a one-way.

Oh, track details for the setup: outdoor asphalt, med traction from a spray liquid of some kind, flowing layout, long back straight (160').

Thanks for the ideas John and Evoracer!

Hey guys! I run a xxx-s as well. I am the only one at my track that does. My biggest problem is that I am running a traxxas xl-5 and a 27t moter. I can not compet with the 21.5 with lipo though. It is like the lipo has a much higher output. I run at two different tracks and one changes from week to week and the other dosen't. When I got the car the last guy had it set up mod saden but I run vta. I run a 28t pionion and the red spur. I don't remember what tooth that is. I feel like I am the only one running leagel with the vta class. I don't have much money to put into the car since I run electric offroad as well. (Just dropped 90 on a brushless setup for that since I burnt up my moter last night.) I am currently running the blue belt as well. The shocks are orange in front and silver in rear. It seems to handel good and I like the set up other then the punch and the top speed. It is getting frustrating and I have thought about selling this car. I don't know though. Any help that you guys could give me would be great since I am new to this whole thing and don't know all of the lingo yet. Thanks in advance for any help you can give me.

Quick question karrick

how long has it been since you cut your com an brushes etc? And what are your batteries like old new etc?

That could make a huge diference too
not sure on what your speedi is but a better quality speed control could make a difference too


As for the b fast diff you can buy it in diff ways
I bought mine as complete package comes with machined flat d rings the diff balls a captured thrust bearing and two speacial thrust races
place is called B-Fast products
u can find a thread of there's on the elec off road section or just google them
