sorry if I jump the gun but I guess since the worlds is right around the corner we'll see all kind of crazy stuff.

Josh you spoke of BIG THINGS TO COME are they working on a new suspension

Well, I like the new car. The new black color looks killer.

And let's face it... if these Tamiya parts are better than the Corally's, this would be an improvement. So if this is a faster car, I wouldn't totally care if it's 70% a Tamiya .

I know they are working on something (they always are) but I don't think fishers car is close to a finished product.

Apparently the "golden ratio" was only gold plated? I'm guessing they won't call the new car a "Phi" if the ratio changes. :-D Man, this is too easy...


Okay, so on a more serious note... The cars that this appears to emulate aren't really known for being great on foam tires. Wouldn't a departure from the golden ratio potentially hurt the car on foams? Has that market dwindled enough that it doesn't matter as much?

it could be alot worse

at least it doesn't have losi parts on it, if it did i don't think we could show my faces at the track anymore with how much we make fun of the slosis

We have our state title coming up this weekend and ive got my Phi weapon dialled, have posted a Youtube movie of it so you guys can see the car and our track, enjoy.

That black on the proto car looks weapon.

I know Fisher has been running a tamiya based suspension for a whiiiiiile. He's played with it on several occasions in the past.

The Prototype is indeed using a lot of Tamiya parts, as they will be basing the new car on the TRF416 geometry.

Half Corally, half Tamiya......... sounds like the new Xray prototype.

this is comming from the guy who is up for a 'wrenching intervention' in which my friends take my tools away so I can't do damage to my car. So double check and question my info:

Couplers dictate your chassis hight and angle which has a major impact on weight transfer. Pending position they can raise, lower or angle the chassis plate. Higher plate gives more roll, lower gives lower cg. If the front is low and the back is high you keep the weight on the front end at the expense of a looser back end.

**couplers can also be used to create anit-squat/anti-dive/kickup. Ex. the front coupler is up and the back of the front coupler is down gives you 'kick up' which can be used if a track has bumps.

hope this helps and if someone else reads this with a correction, please do so.

Running the couplers down lowers the roll center and increases the weight transfer to that end of the car (which will increase roll). Running them in the up position does the opposite. A lower roll center is often desirable on carpet because the rate of the weight transfer is lower, and therefore the car won't create as much grip instantaneously, but will ultimately have more. Running the couplers in the down positions will decrease the rate of roll of the car, will feel smoother, and will create more overall grip.

It is a general rule of thumb in vehicle dynamics that the height of the roll center should be directly proportional to the center of gravity of the car. If, for instance, a car has a much higher CG in the rear than the front, then you would have to have a much higher roll center (relative to the front) in the rear, also. This will keep the relative weight transfer balanced. Since the Phi has very similar CG's front and rear, the car often works best with the couplers at the same height. Many times people will run the rear couplers up in order to facilitate more weight transfer to the front of the car. Whether or not this works well is entirely dependent on the rest of the setup.

Experiment with these coupler positions and find the best balance for you and your car.

Nice description Brian <applause...if I could>

Thanks.
