HOLY ****!

Just crunched numbers on this.

The Novak 5800 setup will handle up to 7 cells at 1.2V per cell. The motor spins at 5800RPM per volt.

After crunching the numbers here's what I get.

1st gear ratio: 4:1
2nd gear ratio: 2.6:1

Tire diameter: 3.4"
Tire circumference: 10.7"

Motor RPM @ 8.4V: 48720

So, after doing the math:

Max speed if in 1st gear: 64MPH

Top speed: 98.7MPH

Of course this is all in theory. Wind resistance will make the top speed a good bit lower, but still...not bad for a pile of junk that was laying around.

Sounds interesting. Can't wait to see how it works out especially with the 2 speed.

With that kind of power you might want to go with foam tires. I doubt the rubber will be able to hook up.

I've got a project going with a ntc3, 2 wheel drive, 2 speed. I think the record is held by electric. What wheels and tires are those? I'm using a 37 Chevy pro mod body and your wheel/tire combe would look killer.

JasonInAugusta · 01-25-2006, 01:18 PM

I won't be running against nitro drag cars, just the touring cars that the locals think are fast. ;)

Rear wheels are Torkerz with Pro-Line Striker IIs

The Torkerz are a pin drive, not a hex.

Fronts are narrow 1.9" HPIs (I think they're discontinued) with these tires.

Wow this is awsome! Looks like I'll be starting another project soon!

Sweet. I made a pan car/dragster but lost interest as soon as I finished it.

It has a custom G10 chassis, no suspension, solid axle rear, direct drive, 32p gears, buggy rear tires and sedan front tires

Heres my axle, maybe it will give you some ideas

It spins on 1/4x5/8 bearings and uses 1/4-20 wheel nuts. That is a T Maxx spur bolted directly to the shaft

im not positive but i think the lhs has a set or two of those front rims in the bargin bin, if you want ill take a look and see if you want me to.

xtman · 01-25-2006, 06:43 PM

If you ever make any more of these. LMK, i have a Novak SS5800 just sitting here waiting for something.

Crawlerguy851 · 01-25-2006, 06:58 PM

I thought you were using Duratrax Street Trac tires, those could be an inexpensive alternative.

RD400 · 01-25-2006, 07:09 PM

JIA, be careful with that 2 speed, the clutch finger for 2nd gear will rip the pin right out. I did it in my HPI three times. Thier 2 speed can only handle down to about a 12 turn motor

That is the two speed for the electric TC?

JasonInAugusta · 01-25-2006, 07:40 PM

Yup, the electric version.

RD400 · 01-25-2006, 07:51 PM

Good luck, if those rear tires hook up well it will eat the 2 speed. Tires that big should have a heck of a lot more traction than my little TC tires. If you need extra parts for the 2 speed, I got them.

JasonInAugusta · 01-25-2006, 08:18 PM

grr.

I kinda thought I'd be pushing the limits of the 48P gears.

We'll see.

If they do, grab them and lmk. Thanks.

bigdogrod · 01-26-2006, 07:44 AM

nice job, that hpi chassis should be pretty stable, i like how the wheels are tucked in the fenders too.

i did mine on a pan car chassis

motor is a 15 turn just to get it to move. i built it for the fast and furious thing i've got going on (have the supra, eclipse, skyline, and rx-7)

a better shot, body needs to be lowered a bit tho

this is the real drag vehicle (besides my new era rail)

chassis is 10l4, motor is 6 turn cobalt, novak 828, and anything from 8 cells up... rc car action did almost the same car, but used a 12 turn and 8 cells, their radar'ed top speed was 64 mph.. i think i should beat that..

although it's got to punch a big hole through the air w/ the truck body..

Nice job on replicating the charger

looks like the real deal straight from the movie.

thebigJAT · 01-26-2006, 09:07 AM

Excellent idea.
Excellent execution.

The color though. Do you have anything in mind?
Single color, or something more graphically intense?

(cage?)
