in need of help

[ResinRick]

I need some help. the orange car is the car me and my sun made for last years cub race it did OK first in pack and 3rd at distric... I made the new car this year it has lathed wheels highly polished axles and the alignment is good. I made a small test track it is only 20' long. the problem is the 2 cars are about the same to finish what did I do wrong? the front # of old car is 30 grams back is 112 Grams the new one is 46-96 can this make the diff. or is the track not long enough please help if you can.
Should i cut some more from under the front or ?

ResinRick, c/g of orange car is good , try to match that. New car looks very nice , but it has a lot of body surface.

agrees with wheeler the center mass is more inline on the orange car where as the black widowish looking car the body is quite a bit bigger with the fenders.

I think you could lighten the front up by removing some wood and move it to the rear. Run the cars on a 42 ft track and I bet the new car pulls away in the flat.

Our opinion is that 30 grams on the front is heavy for a smooth track, let alone 46 grams. You are loosing a ton of potential energy, and that will kill the speed, regardless of track length.
If car set up is good, and track being raced is aluminum (or in good shape)) I would shoot for closer to 20 grams on the front.

similar question. Our car was beat down the ramp but stayed with them on the flat (but two car lengths back) are we too heavy in the front? Blister heat(stock) Dec.

That was heat #9 in the December stock race

Will, most cars slow started in the yellow lane.

I took a look at heat number 9 and it looks like you could gain a little if you would be able to keep that steering wheel on the rail the entire length of the track instead of bouncing off so many times.

We have 5 cars to pick from to send in to WIRL for the Rookie. Currently setup as short wheel base, but we can move the front wheels on a couple. The front weight is as follows, 16g, 18, 20g, 24g, 28g. If I was to grade the allignement I guess it would receive a C+/B- using a WIRL curve. Is 16 too aggressive?

Spindoctor, I would go with 20 gram.
