Is this DJ's car?

Just wondering, casue if you look closely at the rear arms, they've had material removed... and they're the old style... Hmmmm

Ed
If I'm not mistaken that is EJ Evans car....I thought he runs Pole Position and Redline motors.

I have some of the same arms....old ones dremels out but have not tested them. Not sure they theory behind using them. maybe stiffer then the LW stuff but still light?

Thanks Martin. And thanks for the being such a good target on the podium. Another couple of days on carpet and the car would be VERY good. Too little to late hehe. BTW, carpet rocks, it's a shame that there aren't any carpet tracks within five hours of socal.

I believe Martin was running a front one way and a center locked pulley. Atleast that's what I saw when I was checking it out, I could be wrong of course because I may have been trippin.

The car with the old suspension and material removed is EJ's. He had a top five run with it in his first qualifier but was DQ for a small mistake in tech. I believe I had a lap removed from my first mod qualifier because I forgot to marshal...it turned out okay since I broke on my first lap

The big difference between the old and the new suspension arms is their lenght and not the weight. Lightweight suspension arm is just what Tamiya calls them. The geometry is the key so some drivers use old short dremeled out (lightweight) arms.

Some folks were asking for my vegas setup. I ran the same setup for both mod and 19 turn....

Tires : glue half of front sidewall

Front:
Front one way : yes
Center one way : no (locked)
Droop : 24mm to top of axle
Springs: white
Oil: 60 orion
Shock pos:
-outer hole on shock tower
-outer of two holes on arm
Inside Upper links : 2mm spacer
Ackerman : front holes on knuckles
- swept back bell crank
Blocks : d and d - no spacers
Wheelbase: 3mm forward
Caster : 2 degrees
Swaybars : none
Toeout: none
Wheel hub spacers : 1mm
Belt : position 1
Ride height: 5.5 to 5
Lw suspension
Camber: 1

Rear:
Droop : 25mm to top of axle
Springs: blue
Oil: 60 orion
Shock pos:
- One hole in on shk twr
- Outer of two holes on arm
Inside Upper links : no spacer
Outside upper link: 0.7
Upper link length: outer hole on upright
Blocks : d and a - no spacers
Upright : 1 degree allum (total 2.5 toe in)
Wheelbase: 3mm forward
Swaybars : none
Wheel hub spacers : 1mm
Belt : position 2
Ride height: 5.5 to 5
Lw suspension
Camber : 1.5

Mod Motor : 8x1
Gearing : 102 and 25

19 turn :Orion Element
Gearing : 104/38

This setup had just a little push in mod but perfect in 19 turn. For 19 turn I ran the same setup of tires for all four qualifiers and the main. In mod I ran 2 sets of tires one on the first day of qualifying and the other for the second day of qualifying and the main. For mod I would probably make the following changes to add a little more steering.

* not glue front tire sidewall at all
* lay down front shocks one or two holes
Martin-

Congratulations on a great run. It was a popular win. Great job.

It also adds a little bit of flex to the arm as well.

ed - sure - my setup is based on Marc's but more stable, as I don't have the finger twidling abilities of the champ.

nexus - yes, front one-way and locked center pully.

rod - yeah you guys got me good with the bubbly. I hope someone got a picture of me falling on my $ss of the back of the podium

Mark - Thanks

Cheers Martin,
I'll let you know when I've posted it up.
Just out of interest, what was the differences between yours and Marcs setups?

Thanks
Ed

Default Mine v.s Marc's Setup

Ed,

Marc would need to confirm this but I believe the differences are as follows:

Front Camber : Mine 1.0 Marcs 1.5
Caster : Mine 2 degrees Marcs 4 degrees
Front Shock tower Positions: mine outer holes Marcs : 3 holes in.
Front Tires : Mine : Glued half way uppsidewall Marcs : no glue
Rear Toe In : Mine : 2.5 Marc's 2.0
Center one-way : Mine : none Marc's : yes
suspsension : Mine : LW Marc's Old 415 suspension.

I think my setup was better for 19 (due to drag brake from motor) and Marcs was better for mod as his has more steering.

Nexus,
His car never went through post race inspection after he TQed 19 turn, I beleive. Some one grabbed his car off the track and took it back to the pits. When they brought it back it was too late and they made the diecision to DQ that run.
Later
Jim

Thanks for your involvement in this thread Martin.

Did I see Marc running the LWT suspension on his foam car?

Actually martin, one last Q.

Was it the MS or MSX you were running? If the MS, I take it you had 2.5mm chassis and all the body posts in?
And hate to be a pain but do you know what chassis thickness Marc ran?

Ballsie, Yup you did I would assume that it allows you to run the car stiffer, with the shocks further in on the arm.

regards
Ed
