2016 cub car

I know I know.... it should be thin to win... we went old school , but are using good components speed axles some of Derby dads best wheels along with Red rocket bore polish and graphite from John. We did hollow out the majority of the body Who know we might stand a chance.

Sweet paint Ramone!

Thanks ...we have had fun with it...las year we really did it up right ( or so we thought) First year we didn't make the cut for district in 5 years ... I have a car we built with my daughter that has not lost a race( maybe just a lucky build... but we copied that car with this one but we have a better paint job on this one and it was before Istumled on this sight. So we have better wheels , axles,graphite, and a lighter body. So we will see how we do... I really need to drill the axle slot but don't have the jig... Hoping to find a way to get the right cant. I talked to John he is hoping to see the new siver bullet ready to sale and ship soon... I have a feeling it will be after our race however.

 

[Rocket car]

Very cool!! I like the fade job on the paint!

 

[jrbryant68]

Thank you... I found Spaz Stix paint for RC cars, but it has some great colors and goes on nice and even

 

[Crash Enburn]

Airbrush then, huh? Looks like I'll have to get myself one of those. /images/boards/smilies/smile.gif

Great looking car!

 

[jrbryant68]

Actually this is spaz stix canned paint... I would love to learn how to air brush.. I just did my best to blend the colors. The tribal flames are stenciled. There is a company called Automodz that sells primarily on ebay. I don't think this would be considered any conflict with Johns stuff, but he has all kinds of stencil patterns. I picked what I wanted and told him the size area it would need to fit it and in about 3-4 days I had my stencil with a spare set just in case. If you want something that isn't the standard ones you see over and over. I highly recommend.

Great work Jr! I like the Spaz Stix paint, I use it to paint my Street Rods. Easy to work with too!

 

[Quicktimederby]

Very cool!! Make sure to put some tape over the bottom of the car to smooth it out.

 

[jrbryant68]

Thanks for the tip... Had thought about some clear tape ,, but then thought '' Man wonder if a sliver of balsa wood from a wooden $1 wooden plane kit would be better what is your thought?

 

[Kinser Racing]

Tape, a piece of vinyl or Monokote.

 

[Quicktimederby]

You can use whatever you would like. I would just make sure it gets covered. Packing tape works really well.

Ok so I had to weigh the car to see what my weight is for the body... where do I need to be wheels and all before adding tungsten.. I am worried my baby is too heavy...Even after hollowing out nearly all the body it is just under 2oz. Any suggestions? I think I can shave another 1/4 to 1/2 oz if I am really aggressive

 

[BulldogRacing]

pics help a ton, lets see what you're talking about

 

[jrbryant68]

Bulldog , Kinda hard to get a good pic, but if you look up top you might see what I am talking about. I used my Rotozip and routed the whole underside with the exception of 1/2 to 3/4 in on either side of the axle. I am at about 1/4 inch in actual thickness with the exception of the windshield and seat. I know ( or maybe think is a better word)if I was running a thin wedge I would probably be around 1 and 1/2 oz. Should I scarp it and start over? Or is that 1/2 oz going to be something I can cover with weight concentration, good wheel, prep axles and graphite( we can't run oil here)?

 

[BulldogRacing]

I see now, I had to click on the word image here on my end, that is a cool car man, you gotta run it as it is! Just follow all the speed tips you can and you should win most scout level local races! Go get um! That is a cool car!

 

[Crash Enburn]

JR, what's your goal here?
Make a great looking car? You did.
Make the very fastest car possible? That is another design.

You could hog out more material, but you run the risk of ruining the paint job. Personally, I'd look at maybe lightening the car a little more (leaving 1/8" of material on either side of the axles), but would just enter the car as is. With the heavier body, just put all the additional weight behind the axles.

If you want to try for an all-out speed car, go ahead and make a second, and submit that one, too.

 

[jrbryant68]

I cleaned out as much material as I can...and still feel safe around the axle slots... I think wheels and all I am probablly 2 oz.

 

[jrbryant68]

Ok here is the latest news... thanks to some amazing help the car after some tuning runs 2.99. on 42ft track weighing 5.01... we run graphite . std axle slots and For this much body, I thought that was pretty decent. I know it has to be much lower than that to compete at a national level, like Mid -America. Things I have heard but don't know if they would help. Graphite coat the wheels... (worry that might cause slippage) graphite the body near axle slots(can't uses washers or bushings) any signifigant gain in it? We use std kitchen scales at pack and district... not sure if I should go in heavy 5.10 and shave the putty at the table? I really would like to get this thing down to 2.97... so any of that magic derby potion around I could use a drop or two. OR JUST MORE GREAT ADVICE WOULD WORK

Not sure if you are running a three wheel touching rail runner or not, but you want grip, coating the treads with graphite is a marketing ploy, you need grip to run the rail smoothly and fast.

I believe you can use washers for Mid America, so keep that in mind!

Last year at Mid-America my boy ran his Enderman car, no fenders and semi-lightened wheels, but not Mid_America cut wheels in the graphite division, had runs between 2.9957 on the first heat and 3.0246 for his 6th and last heat. Finished with a 6th Place Wolf Trophy, 6th of 22 Wolves, 33 of 114 Overall.

Does that give you an idea of the level of competition at MA? Run your car, you may be surprised!

Hope that helps!
