What is the weight of the car with the lipo set up? Is is too lite for a Roar race?

I just got the set up the other day and it looks good but its still being tested and is changing alot from what was explained to me. So far it looks good on smooth tracks.

B-4 weight is 53.5 oz with set up as posted above..

Car is very good on the bumps , we had a big event this week-end (N/w ECT 156 entries !!) .

The layout had a big-O bucking wash board and the car was a lot smoother than the older weighted set-ups...

1 oz in back and .5 oz on the rear chassis, check the "worlds" set-up for the B-4 on Rc10.com....

[QUOTE=Wes Briscoe;5301666]Another thing that I did not see mentioned is buy the plastic replacement parts and not the carbon. The carbon parts will break much easier.QUOTE]

The plastic does break less... But if your track has any sort of grip, the carbon carries much more corner speed.

Try this for a 'lightweight set-up'

It should be very close to what BT and Pudge are using...

Last sheet I saw they had a slightly longer wheel base with 1/2* rear toe added on the hubs. Also a full length rear spring, but for the grip of my track, the cut spring stablized the car out a little more.

The total car weight is 53.1 ounces. ROAR minimum is 52 ounces.

Default light setup

The 4th hole,

were exactly to drill it, same spacing as the rest? I noticed in the picture above that its not inline with the rest, a little lower.

Just wondering how much to cut off the spring? (ie. coils/length)

Drill the 4th hole using the same spacing. Just bolt up a second rear tower overlapping the first and off set it to drill the hole.

Yea thats close to what ive seen them run. I ran my car at 1515 grams all weekend at crcrc and it was pretty good. It just took me a while to get the track down.

2coils is what I did, it is mentioned on the comments section at the bottom of the set up sheet.
