I hope this is in the right section, but I am having a little issue with chassis identification. I went ahead and did a search online about USRA rules. Now I know I have a Zap chassis and I am pretty sure I read in the USRA rules it said the Zap #100 chassis is legal for box stock 12/group 12.

From the picture its the one with the green body on it.

Hope some one can at least point me in the right direction. Thanks for any help in advance.

Mike, Not clear on your question but I think that is a ProSlot chassis.

[Big Mike]

Mike the chassis with the green body on it is a old proslot I15 chassis from the 90's and the zap chassis are no longer legal in usra racing being they are out of production and unaval. the car on the left is a proslot tripod which is still aval. and usra legal. Hope this helps, Mike Chmielewski

When did INTERNATIONAL 15 chassis ever have to be approved for the INT 15 class??? There is no product approval for Int 15 chassis and never has been.

It was always a "scratch built" class and the only "restrictions" were materials used. These changed over the years of course.

But Int 15 chassis never had to be submitted for approval like Box Stock chassis. There was also NEVER a commercially available rule for INT 15 chassis. One can still build their own design and race it correct in INT 15 correct?

[Ron Hershman]

The Green body chassis looks to be a Zap or maybe a P-S chassis or a "knock off" of a Zap chassis.... the Brazilians did this for a short time.

They were all legal to be raced and never had to be submitted nor be commercially available.

The Orange body chassis is a P-S Tri-Pod Box Stock chassis,

Well my question was basically what type of chassis is that one on the green car; because I am pretty sure I read something on OWH or a PDF of the rules, saying that they were going to allow #100 Zapp chassis, and I wanted to know if this was it or basically is it legal?

Also if its a ProSlot chassis then are you saying it would be legal? I know what the other 2 cars in the picture are, the only one I am unsure of is the green one.

[Gator Bob]

Green car is a International 15 (I ran one in Box12) ProSlot wire and brass chassis not in production. Not a ZAP. You can see the dif in the advertisement posted.

To get straight Listen to Big Mike Chmielewski he is a USRA Div. 1 Tech Director

BTW: you can run both wire and steel in the MySeries rules down here in Florida.

[Big Mike]

Ron is correct on the int 15 chassis never has been a submitted chassis but the question on the green car is wether or not its legal for box 12 and the answer is no it is not legal for the nats or any usra box race. Now if you really want to use it it can be used in the I15, c12, or big dog 27's or opens but not box 12.

Really? I am suprised I was told buy my local track it was a Zap and it does look like the ones in the pictures, the only difference is that if you notice I still have the front weights on mine. The only noticeable different to my UN-trained eye is those front weights from those drawings of the Zaps.

Also thank you for that answer, I knew it was MySeries, but when I read their rules on chassis it basically said "refer to box stock 12 USRA rules", and I would figure more people would be USRA knowledgeable rather than MySeries.

[Gator Bob]

I have the ProSlot too, at my local track in Melbourne most everyone calls it a Zap.

Mike, Are you going to run MySeries?
What is your home track?
What classes have you been running?

I'll help you out any way I can. Just ask or PM.

Suggestion - Run the steel chassis in Gr-12 and the brass and wire car in Group-F.

[CFL Mike]

Actually it sounds like we go to the same place; I go to the Raceway in Melbourne.

I am going to try, I just got back into slot cars; found my old slot car box a few weeks ago and decided to give it a go. Though as you can see there are a few things I need to do before even trying to race.

[Bartx7001]

The WIre frame is a Zap box 12 chassie. Zap had and a 100 and a 101 chassie. One was a tripod and the other a perimiter. I have ran both. The main rails were .063 wire and the front weights were larger than the Int 15 chassis. There used to be usra aproved but were not competitive on swoopy full glue kings. They were the best on flatter hillclimbs. They have since fallen off the aproval list after Craigs passing a few years ago. Using the internet archives and going back to 2005 you will see the zap 100 and 101 part numbers on zaps webpage.

As said before, the chassis on the car at the left is a legal to use Pro Slot chassis. This is still on the USRA list and is legal for Box 12 in the My Series. The Zap chassis would be legal for Group F only, and would work very, very well in that class on the hillclimbs. I myself use an old Yeti wire frame that works fantastic for group F. Most everyone that runs the My Series Box 12 in Florida runs the Koford 530 series chassis, but there are a few Pro Slots out there that were sold as RTR's. With a good motor matched with a well set up body, that Pro Slot will be competitive.

[CFL Mike]

Thanks guys, in fact I have been finding that out, that this chassis is so much better on our hillclimb track than the other newer chassis out there (like my ProSlot red bodied car). I have been running it on a rather small hillclimb type track.
