Caster comes from the c-hubs and these are in the normal position. Only the steering arm was turned upside down, but it is symmetrical in a horizontal axis.

Unfortunately my first print of the new bulkhead design failed. I started a new print today, but won't have it in my hands before monday (if at all...).

You guys know me for loving to drive scale body shells. The Civis body was nice, but is very narrow (183mm), which induced a real grip roll problem indoors. Two good friends now really got into FF cars and also went for FF03s. They are real VW fanboys and bought the Tamiya VW Scirocco body. To my surprise it is 189mm in front and around 188mm in the rear. These parameters are very close to my T4 width and therfore fits perfect on my chassis.
Now, as these guys reenact the VW Scirocco Cup, I thought I am going to join I copied the livery of one team of the series as close as possible:



And this is my body:









The red looks much to bright on the pictures, but it is just the normal Tamiya rattle can red...

Again, everything about this build just screams - "low-budget"!! Box it up and send it to me... I'll run it for you, that way you don't have to be embarrassed to have it seen whilst you're at the wheel!!



Love it, actually!

Here's my VBC FF17





And here's the FF03



And sorry for whoring out my cars in your thread... if you, or you know someone, are interested in the FF03 let me know as I would like for it to go to a good home - haven't run it in a year or so... It can even include the HW esc, and spektrum S6240 servo if wanted.

btw, great job on the 'Roc, looks beautiful!

Thanks! As long as it is FF related you can „whore“ as much as you like
What is your resumée after having driven the FF03 and the VBC?
I forgot to mention, that the Scirocco shell is the lightweight version (of course)

Unfortunately, haven't run the FF17 yet (and I actually have two )

Our track closed end of January and I haven't run the front drivers since...
The track I go to is almost 4 hours away, and I usually run 1/12-F1-USGT when I go. I do wish we had somewhere close to run though... Have a FF04 & FF04 Black edition that haven't ever seen the track either (along with an old VBC FFTwelve I picked up awhile back)

::sigh:: I really need to move. . .

Needless to say, I live my FF RC life vicariously through the inter-webs, and threads like yours. Plus, a lot of FWD Forza and Project Cars 2!!



And my FF04

Oh boy, oh boy, did we had fun today

VW Scirocco bodies, 17.5t motor, box stock tires, Tamiya rims... Super close fights, a little like in the movie "The italian job". Three drivers battling it out on the racetrack bumper to bumper, wheel to wheel, parallel If one made a small mistake he instantly lost two places or we all crashed. Just awesome!



My car was equipped with a 10.5t motor which I turned down to 45% on the transmitter. This way I lost around one meter on the straight which I fought back in the Infield due to the lightweight chassis and better cornering performance. That sounds pretty unequal, but was pretty good.





The stock tires gave an impressively high amount of grip. We just "woke" them up with tire additive for three to five times. I for myself then stopped and just cleaned the tires with brake cleaner. We also didn't glue them to the rim and never had a problem. That was very surpising. The prize is also very attractive, around half of a premounted race tire.

The car drove very well, again I brake to prevent overshooting, then just pull the car with the throttle around the corner before even reaching the apex.

Awesome!! Sounds like a ton-o-fun. How in the world were you able to run the tires w/out glueing them to the wheel?? Craziness!

Thanks for sharing!

OK! The second 3d-print was a success! The geometry is spot on, no collisions found. Now it is Shapeways turn to make a strong part from my data.







In the meantime my job will be to mill shocktower, motormount, camberlink brace and another connection brace on the back of the motor. The motormount will be made from aluminium. I am really not looking forward building this part

While waiting for Shapeways to send the parts (last november week), my Friends and I continue to reenact the Scirocco Cup. The box stock tires became very sticky and had to be glued. Because of this new grip level, the driving really looks like the real thing. If we touch the curbs, the inner tires took off just like in the picture of the above post. Awesome! The fights are still close and exciting as hell!



Today it was time to rebuild the car. I found some loose screws, grey oil and some wrong settings. The Tamiya shocks got service for the first time. The oil was a little dirty, but there was no air inside. The rebuild went on without problems. Now the car should be easier to drive. I still wonder why my rear toe in was so off. With 1.5* it is no wonder the rear was uncomfortable in some situations
Really unpleasant is that the Tamiya rims are grinding corners into my front arms. The rims are going to loose some material!

Tomorrow the wild hunt will start again

The hunt is over (for this weekend). This day brought up some surprising thoughts.

Starting next week, I will own two FF cars. One which will be a normal FF03 and one that will be called KR-MF. The last mentioned is my protoype and will be discussed in this thread.

Why this decision? Well, the MF was originally created to raise the bar and be on the pace of 4wd chassis. It is light, powerful and all cfk & aluminium. Because of that, it is much too light for the Scirocco body. On friday and sunday I had pretty severe traction roll. Setup changes did not improve the situation. The chassis is not heavy enough for a scale body. So it will become again what is was meant for: A advanced FF car with a powerful 10.5t motor, Bittydesign M410 ULT body and Sorex 28r tires. In two weeks time with the Shapeways delivery the KR-MF will be born.

With all parts that are left, I can nearly build a full FF03. And I will This chassis will get the Scirocco body, a 17.5t motor, the box stock tires and 5.546 gearing. It will then participate the Scirocco Cup starting next week already.

I don't think that high CG is your problem but you are getting more cars so that's good
