So what does it weigh(pun intended) as pictured?
How much weight needed to bring it up to max?
So, is this going to come as a kit?
I have the Mr B parts on order. The cub weights should be here this week. Shields should be here this week. So, now I just need one of those supper cool bodies!

I sell the bodies on the Pinewood Illuminati store where I sell the weights.
Special deal for you... buy 1 get 1 free.
CNC routered bodies are far superior to laser cut...
If I remember correctly...car body comes in at about 14g with air deflectors and fenders... so I should get about 4oz of tungsten in it.

  Eagle... see how I use 3 scales to balance the wheels... gotta try to balance them to a point... due to the geometry of the triangle the left rear wants to be heavier. So ya gotta shift weight to the right side. |

Laser-Man I see. But if that is a big problem why don't you shift some of the weight from the left rear behind the axle to the right in front of the axle as well?
Or, better yet old cub weight on the right and new on the left.
I could spend a lot of time here, but I would need your car, 3 or 4 scales a track setup and a lot of time to play.

eagle, he would lose too much motor moving the weight over and forward. I have seen a photo of one of Joe's cars using only one wheel weight on the dominate side, actually making it heavier than the left side....numerous possibilities, only one can be the best for any particular set up..

Kinda curious if I am pushing too much engine here.
Those tungsten rounds come in at about 14.5g... plus another 25g behind the axles in Cub Weights... plus a full row of cubes...
About 2.5 oz behind the axles altogether.
What do you think?

About 2.5 oz behind the axles altogether. What do you think? I think you're fine Joe, you might even want to push it a bit further if you know you're going to be running on something smooth like a league or MA track. I'm not sure why you went with cylinder weights in the rear, I can only assume you might want to taper the rear of the car,or you wanted to keep the weight a hair closer to the axle spur. You're only at about a +5 in leverage which is fine, and should run good down any half decent track. Our Caution car has a full wheel weight set-up with a +8 leverage, and it always runs straight, with never a hint of instability. However, that is running on 2.3g +/- wheels, running on light 1.3g MA type wheels could have different results, you wont know until you try it. If you're not intending to taper the rear of the car, I would swap all of the the cylinder weights for 3 cubes (same weight +/-) and position them against the right side, this will allow better balance on the rears. It will also give you a larger motor, albeit very slight since the center of the cubes mass is further back (higher on the hill) than that of the cylinders. |

Good info.
Thanks Ember!
I originally wanted to place cubes back there like you suggested but then thought that a tapered rear may be better...
I’m still up in the air a bit on it. Betcha if I use cubes back there to bias the weight then I could probably bring those cubes in front of axles right up against the axle spar... bigger motor... like you said.
Forgot to even look at the MA rules... not gunna spring for $50 wheels though... so I have to figure out what I am doing there.
Good stuff.
