Now the HPI F10 setup with Vintage wheels and tires is 200mm = face to face is 7.8125" or 173.037mm then with the 6mm offset vintage wheels & tires it comes to 200mm with wheel and tire mounted.



The SP-1 is 5.4375" or 138.1125mm with Tamiya old school wide rears 200mm.



Vintage wheels w/6mm offset is 6.750" or 177.45mm short 12.55mm to get to 190mm or 6.25mm each side.




With the Aluminum adapters I did for the pan cars to get them to 190 - 200mm are the same adapters that are going to work for us running 190mm on our F1 cars W/Vintage wheels on the rear with there 6mm offset.
The Shoulder of the adapter .335" or 8.5mm the head of the adapter or hex is .170" or 4.3mm and a 2mm inside face.


Sorry I led you astray! I sent you an e-mail indicating my embarrasment! Unfortunately the adapter project may not be as simple as we had first believed.

I don't see how your pan car adapters attach to the "tammy" parts. That's where I'm stuck, trying to use the same 4mm nut to hold on the adapter and wheel. Not much room for other attaching methods and I can't see how to do it without more fasteners....

Not giving up but we need more ideas to minimize the number of parts that must be made!!!

Take a look at my stuff and let's try again.

WOW! You are amazing!! Wish I would have thought of that....

Oh, I did...on March 14, 2013 I posted pics and parts.

I think I have been successful in adapting the VTA wheels and tires to the Tamiya F1 chassis platform. My F104 Pro is in the process of becoming gas (nitro) powered and until I get another one or parts, I mocked the set-up on an F103. I think the pod and the front suspension will just bolt on the 104 chassis so it should be fine...

The rear is a piece of cake, if you have the right pieces, as has been mentioned. The diff and wheel adapter for the F103 GT from Integy or 3 Racing goes right on and I have one marked "+2" as in mm wider, i think. and I'm right at 190mm wide.

The front comes out around 185mm with the 104 front and wide hex spacers on FGX hubs. That's probably close enough but the axle nuts barely threaded on, requiring special wheel nuts. I like the look of the F103 front end a little better, more "spindely" less aerodynamic than the 104, IMHO, so I used it. With the FGX hubs and 4mm hexes I'm at 188mm. My front end is from 3racing and has adjustable camber as well as caster.


It's post #7300 in this thread, if you care...

Tell me that a Gurney Eagle body is in the works, and a Ferrari with a "bundle of snakes" exhaust system. Please.......

So you guys are trying to push the HPI VTA wheels out to 200mm for looks right?

If you were to take an F103GT kit and switch the rear axle + front end, you should end up at 200mm I would think. Or is the offset of the wheels bring it back to 190mm?

I applaud the effort, but it seems an F103GT kit (used as a donor) would be much simpler.

Not sayin' it's ded, just a bit more complex than I first thought! I have no way of making a 14mm internal hex!!! So you had that taken care of but now I'm stuck.

I see that your pan adapters will bolt to pan car adapters where the wheels normally attach. But there is not a place on the stock F1 adapters large enough to duplicate that that I can see...

Well your both right and yes it has come up in the past, Ned's posts. My idea from the start was to just make adapters, front and rear. then there would be no changing of parts. just slide the adapters on add the wheels and away you go.
I still don't have all of the Tamiya parts from the F104 - Pro. I do now have the SP-1 plus the design we worked I have paid for and have them coming as well.

My Pan Adapters for the pan cars are nothing more than a mockup. The flange and 4 bolt holes will not be there with the final product, the part will be one piece.

No, not 200mm. We are adapting the VTA wheels to the F1 car and want 190mm MAX. That seems to be scale and is actually the rule!

The offset of the 103GT rear end parts come out to 190mm just fine (Mine are 3Racing and marked "+2") They work fine! As I have stated in another post, I have not tried the front end parts and they may very well work also. I prefer FGX parts, 'cause I have them...

The following is my take on what we are working on and why:

The point here is that we are not looking for the simple, obvious, possibly expensive and difficult to find way (I have not been able to find all the 103gt parts in stock as of yet) to convert to VTA stuff, we are attempting to come up with a pair of simple adapters for the front and one for the rear, that will fit over the existing rear adapters and front axles and not require any other rework or parts.

When the VF-1 class was laid out, one of the ideas was easy conversion from a UF-1 car to a VF-1 car by changing as little as possible. That is why he spec tire/wheel combo is a Tamiya wheel type wheel and slick tires. It was thought that although the treaded VTA tires might be more scale and an interesting posibility, the cost and complications involved in using them was not worth it, at least at the time.

As for the Tamiya F104 Pro and others like it that use a end cap on the diff side these adapters can be made to slide over the stock 14mm hub and use set screw to hold them in place with the 12mm Hex center hole is threaded and we use a bolt to mount the wheels.
The F103 type of diff will need to be changed out and yes they can go with the 103GT parts I guess or pick up the new style 104PRO diff or even the SP-1 will work.
