Hey it worked :thumbsup:
It's a SC-18 with a narrow battery tray. It'll have a big block with the pod plates flipped upside down and backwards. The reason for that is the axle is now behind the motor like a 1/10 car ( the rear suspension seems to work better ) and the ride height is now lower while using the 1/12 tires..... batteries will be a ofna 7 cell brick back and electronics will be tight, but I'll get something to fit. I also have spacers under the front axle to lower that ride height and to be able to adjust caster......... The body will be a pain to paint with all the roll bar detail, I'll try and get that done this weekend. what do you think ???? If there's enough interest Bud might make some more bodies :)

VERY nice ZXboy! Were you able to get all your radio in there? what did you use for body mounts? How about a pic of the bottom?

Hey K1M, don't have the radio gear in yet, but it'll fit !! there are three body mounts. One tall one in the rear coming off the top of the damper post, and two on the side down low. It seems real secure, but will have to do a good endo flip to test it out :D I'll send a pic of the chassis with all the gear in it soon..........

We've got the perfect track for a racing class here in Columbus. It is an Indoor Dirt Oval ran by George Hawkins and it is called Thunder Raceway. For directions and more info call 614 205 7299.
The CORCAR forums has a thread about the race track and racing there. It can be found
here. (http://www.corcar.com/cgi-bin/yabb/YaBB.pl?board=cr;action=display;num=1045109861)

There are some photos of the track and pit area in that thread.

They have electricity in the pit area and tables in the same and the area is clean. They run only foam tires and it is a well lit clean race area. George has been talking about putting together an indoor area to run Micros and BRPs in another room (not the same room as the Dirt oval.)

I asked Bud about a conversion kit and he indicated you would have to do your own conversion.

Following the technique and method ZXBoy used you need:

+ Fun Wons 18 (typically too expensive to change an SC18 to a Fun Wons 18 because of different front suspension plate, tires, rear diff assembly, etc.)
+ Big Block Motor Plate set w/ Speed 300/Wattage 370/Big Block motor
+ BRP Pro top pod plate, shock assembly and mount
+ Narrowed extended battery tray
+ Larger front bumper design
+ 12th scale (Fun Wons tires) front foams front and rear
with fronts cut down.

ZXBoy intends on using brick cells because of their smaller width cross section. The radio gear and batteries have a much smaller area to occupy.

If you know someone racing 12th scale that doesn't glue up their own tires you may have a source for your front tires when they are done racing with them...
You'll just need to true them, so they are the same size, unless you need stagger.
Or cycle your rear tires to the front when they don't have the needed rollout height.

Bud: Let us know when those sprint car bodies come in.
Also, will you be running the mod class on oval or road course at da track after June 7th?

ZXBOY
05-29-2003, 04:51 PM
Here's some more pictures.............
The ofna brick cells all melted on me when I tried to charge them up ??
Oh Well....Never liked them much anyways when I was using them in my micro RS4. So I used 2/3 a's in a funky arrangement to fit 7 cells in there. Like putting 10 pounds of S#$%! in a 5 pound sneaker :freak:
I'll try and put it on a track this week and see how it goes......... :D

Sprint car bodies are in. :)

ZXBOY

Hey Coro, The sprint car went good....... It seems a little over geared with the big block and the fun ones tires. I wish there was a bigger spur than the 52T........ I had a hard time fitting batteries, but I have the wheel base altered ( axle behind the motor and front plate moved back ). But if yours is unaltered should be a bunch easier.
Just make a new narrower battery tray to fit the body ( I made mine from thick lexan ) If you look close at the middle picture you can see the lower body mount is a cross wise tube secured with a allen screw on either side of the battery tray sides. drill the allen heads for a small body clip make a hole in the body and secure with the clips. The rear mount comes off the top of the damper rod.
The front tires were gripping a little to much in my test session and if I wasn't careful, it flipped just like a real sprint car, and the body and mounts held up very well...............
Bud I'm going on vacation for a few day, please save two bodies for me and I'll contact you when I get back. Thanks Roy

good news, good news...... Robinson Racing Products makes a 60T spur gear that we here in PA have been running for a while!!!! the part #RRP-1860 New Stealth Pro Spur. Works excellent, especially on a tight road course, in and out of the turns faster!!! Try it out and see what you think. :thumbsup: :devil:

ZXBOY

Yeah,Yeah, That sounds like the hot set up for the big block and fun ones tires............Who sells them ??

zxboy: I ran 60/7 in my F.W. pro at buds track last weekend on the road course with the big block. It was a handful even at that gearing. Very easy to overdrive the turns, I tried some drag brake but it seemed to slow it down too much. On a small tight track turning the throttle ATV down seems to work good too. About 1/2 way through the 10 minute main I was wishing I could turn the boost back up though. But I'm barely coordinated enough to turn the wheel and squeeze the trigger let alone push buttons too!
I'm planning on building a sprint car this fall - I'll probably have a few dumb questions for you then. :hat:

Canbquick: We got SPRINT CAR bodies now !!

K1M:
we have one of our sprints ready, as soon as time permits I will get some photos posted. As a reference, we used 6 AA's, full size electronics (they were laying around), sc18 tires. We will have 3 ready for the last oval race at DA Track.

Guys...
I've seen references a couple times to a 60T spur.
Can you elaborate on the source and if it comes predrilled
for the diff balls?

That's some pretty steep gearing on the Fun Won
for a 60/7 or 8.57:1 Is that with the Big Block?

Thanks!

I think if you do some RAFstering with rollout, :D with the Fun Won tires, it might not seem so tall. I know it seems to work, even running the 16d on a tight road course or in a small area. Those motors love to rev if you let them. Besides, with an SC18 tire I think the gear would very close to the ground.
#RRP-1860 will take 8 of the larger diff balls
#RRP-1960 same gear, drill your own holes
Also, you'll have to hog out the motor plate alittle too and you need a 3/8 X 1/8 bushing.

F.Y.I.
aprox. dia.
Fun Won - 1.75"
SC18 - 1.35"
60t - 1.29"
