I was looking at the Serpent site and saw part (803187) Break pully one way. Is that setup to make the 720 act like it has a center diff ??? If so, would that part compliment a front oneway and make it have the same characteristics as a gear diff but with a posi ?

I'm interested!

We had to use the carbon plate because this track has lots of front traction.
Anyways, in my case there was no way to use the chassis without the plate since I had to disconnect the front slwaybar to prevent from traction rolling.

Its not a diff action. It will be engage only if the brake and trottle applied.

During off trottle the car will glide very free just like asuming the middle belt is taken off.

If using this with one way It does not make any big different but smoother because it will disengage the rear transmission with the middle belt.

When you run a longer main, you will get different wear rates front and rear. Most of the time you will wear the reas faster than front. In the long run this will mean the drivetrain gets bound up, as the fronts will want to turn slower than rear. The 3rd one way as we call it helps to free up the drive train during off power phases (like coasting through corners). This helps to smooth out the handling mid corner.

It feels sort of running a front one way (when you are actually running a diff) without losing the braking power.

Also because of the way the 3rd one way is setup, you will also find you get more steering under braking when running a diff or spool up front.
Using this option we loose the brake on the rear tires? If we loose (I guess so), the brakes will be less eficient.....

This is a Braided tubing it is very good for protection of the electrical wire, I have a VXR LiPo battery and a NOMADIO SENSOR that have a Telemetry with the temperature that it is also protected with the tubing.

This is an example http://www.flexowrap.com/pdf_files/catalog/pet.pdf

i think you are miss under standing how it works you have to see on the car or how the assembly looks. it does not take away any more brake than you put on or take off . its a tunning option it may not work for every one driving style

Well... It is a oneway on de 24t pulley. It means that the oneway will engage on the on-throttle scenario. When you apply the brake, the oneway will desengage..Isn't it correct? I mean, with this optional we will only have brakes on the front wheels.....
Can anybody confirm it for me?

regards

yes you are right how the oneway works but think about what you said about the front wheels .the only way you get four wheel braking is with a solid up front. the oneway and the diff up front the wheels spin at two different speeds when you are cornering off power

Default New Ackerman

Hi Guys

Does anybody have more info on the new ackerman for the 720? For example, the diff insert positions and the result of each insert position. Which position will give you more steering and which insert position will give you less steering?

Thanks
