sweet, Thanks!
Also just curious... with all the emphasis on weight savings, why the use of all steel screws? Is there an issue replacing them with alloy's down the road?

Yeh thats what I thought. Most of these cars will be way under weight with LiPo in the future anyway so I guess it doesnt matter
BTW I am still going through building the car... I am very impressed at the quality of all the components in this kit... its pretty much all the good stuff you'd have to buy aftermarket for any other car. Excellent kit... I am pretty sure this will attract some attention from the local club where most run R5's and L4's.

I did find one build issue. And this could be whats happening for another guy a few pages back where the chassis wasnt sitting flat.
The large screws for the front steering bulkheads are too tall even with tall spacers under the lower arms. THe top of the front screw binds against the uper A Arm. Any thoughts on this? or did I miss part of the build where this shouldnt happen?

Here's what I have from memory without looking at the car. The setup wasn't perfect. I've been continuously experimenting trying to find what I want with the car. This may work for some, but not all of you.
-Front-
-BMI .020 springs w/ about .010 spring sag
-#5 surelube on kingpins
-6* caster
-5* reactive blocks
- -1 camber
-#4 ride height adjusters
-Servo flat with tall ball studs on steering blocks to fix bumpsteer
-Parma Coral tires
-Rear-
-.064 flex plates (long)
-#4 surelube in tubes
-silva shock w/ 40wt oil and ASC red spring (not sure on length)
-ASC shock mount raised 2mm and medium ball stud on mount (mount also all the way back on chassis)
-battery full forward
-Parma Gray tires
Gearing was 80/49 with a Losi 17.5. It probably could have used another tooth. The body was a Parma Speed 8 LW. I don't remember the rear ride height adjusters. The car was 3.5mm ride height in front and 4mm in rear. The front tires were glued too. The rears only had the bead glued so they wouldn't rip off the rims. The traction was crazy high at 360 for the regionals.
This setup, at 360, pushed a little off power. Then again, I'm not 100% sure how good it would have been if I would have put fresh tires on it. It probably would have turned more. Either way... it's still a work in progress, but something definitely to try. And no, I did not use tweak screws.

Are you guys who bought the conversion kit using the flex plates that came with it or are you using the thin plates. Whats the advantage of each.

Got her all wired up and ready to go over my lunch break. Here are some shots. (sorry for them being a bit burry, I just used the last setting on my SLR when I took these and it was prety wide open...)
So out of the box with moving the ESC cap to the other side of the antenna, the car ballances out perfectly.
No real setup on the car... no goop in teh tubes yet or on the king pins..
Oh and the weird looking thing on the end of the axel is the Slapmaster thrust bearing... worth its weight in gold. All the bearings are ceramic including the diff balls brought over from my former 1/12th.

Also, before I go spending $37.00 on Shur lube, I already own many weights of heavy silicone oils (3000,5000, 7000, 10000, etc...) Any idea what Shur Lube 3, 4 and 5 equate to in standard silicone weights?
