Ran the HB C12 Mark-2 for 3 rounds on Sat with Purple/Grey foams and full addy front and rear. To much front end so dialled out dual rate. Round 4 & final switched to Audi R10. Car was poooooooo all day yet was keeping pace with those of similar ability as raced against at the SSO R3. Car was just to iffy. Didnít know Roger M was spotting for me and trying to help. Thanks Roger. Listend to him & PDW but got no were with car.


Sport & Open Modified

FRONT
BMI .22 Linear Springs
No Oil on kingpin
3.5mm Ride Height
5' Castor blocks / teflon washer either side
Camber, set run foams flat
0' Toe
Laid Down Servo / Sanwa 141

REAR

BlackArt Audi R10
Nosram 10.5BL on 58mmpr (or there abouts)
Steering exp @ 20%

Had a sleepless night thinking about setup.

Woke up Sunday and had a idea. Choose to pull the front and apart and clean the king pins etc. One was a little stiffer than the other. Also upper A arm on left side had stopped falling under itís own weight (previous contact with wall may have caused this). Reamed out the steering blocks that I hadnít done before.

Trimmed the car back up on carpet, no shell or addy. At this point I noticed how it wanted to steer without addy on purple/grey foams. So for the open practice heat went out on purple/greys with Audi R10. Race control posted lap times from this and I was pleasenlty surprised to find I turned a lap 0.1s slower than I had managed on Saturday.

Round 1
NO ADDY Purple/Greys.
Audi R10, used from here on in.
Increased the dual rate on the run to the start line
Noticed lack of grip on rears when leaving on the start tone. As you donít need to nail from the start tone wasnít an issue as your time only startís from crossing the loop.
Ran OK but had to wait 3 to 4 laps before car came to me. On same pace as Saturday.

Front end clean & strip would seem to have sorted Saturdayís problems.

Round 2
NO ADDY Lilac/Pinks
Decreased dual rate due to more steering on run to line
Getting very close to Saturdays times
Still had to wait for front to come in. Rear OK

Round 3
Same as round 2 using the same foams

Round 4
NO ADDY, used Double Pink/Yellows
Recorded quickest time of my weekends racing
Q4 to make my 1st national A final, even it is only the Sport Modified Class

Final
NO ADDY, used Double Pink/Yellows, foams from R4
Finished 9th due to traffic issues. Got a good start and holding 3rd/4th until someone rejoined the track from there crash and all mayhem broke loose.
Recorded a sub 11s lap so happy with that


Roll on Crewe and Duo Carpet & Audi R10

Default nice

Very nice setup jaybee. Car looks very neatly set up and very precise. Who makes the balance buttons that you have under the car?

So, whats the majorities opinion on what is the most common cause of bent shock shafts on this car? I personally have only been through 2 of them, but others at the track are going through 2 -3 per day!

I have read that some think its the battery hitting the shock during hard collisions. However some of the guys mentioned are using tape and the o-ring.

Thoughts?

Yes, it is from the battery hitting the shock during a crash. You have to use tape to hold them in place. The o-ring just doesn't keep the battery in place by itself. I personally use tape and the o-ring. That, and don't crash as much.

Thanks WIITA.....I try I did improve the car a bit by switching over to the Hot Bodies shock (this thing is butter!), and twisting the wires up a bit better.
I can't remember whose balancing post those are......

That is what I do also, just the O ring is not enough.

Are you guys beveling the center piece of the battery locator? I found my batteries didn't sit all the way down into the chassis until I did that. Now the battery doesn't get loose as often.

Sweet looking setup Jay

ThanX Gadget

Car felt good that first round. Probably looked better as it was a little under powered with the XBR esc in there compared to the GTB 4 cell! It made it a little easier to drive but I could really feel the lack of power from the XBR esc.

I think I need to pick up a few more pinions if I am going to use this esc? Was running my 40t pinion (biggest I have now) and the motor was coming off around 150.

I just love running this car!
