Dogbone angle and dogbone "plunge" coupled with toe -in and anti squat.

What Paul has done at xfactory is some solid work. Youd be amazed what the bigger companies don't try or test because its a huge cost to do something that different from what you currently have. Especially when you currently have the best selling car on the market.

If you're looking to improve upon what is arguably the best 2whl platform of the last decade.... You're gonna have to design and test your ass off to make it better. Now, throw this whole new mid motor craze into the mix... It kinda throws off your design plans/timeframe and maybe everything you thought you should do.

toe-in and antisquat okay... but how can the dogbones affect grip? toe-in and antisquai will be the same as stock with my mm-design, but maybe i also have to take the cvd-angle in consideration to get a good handling.

Google "dogbone plunge"

i found this post in the 22 thread: http://www.rctech.net/forum/9082167-post6417.html so the height of the inner hingepin changes the rollcenter, same as when you rise or lower the ballstud. And if i got this right, more friction beetween the outdrive and the dogbone-pin means more grip? (so higher angle means more friction) But how can i change the angle? and wouldn't that mean worn outdrives significantly affect the traction?

+1 I think the c4.x is being used to get the ball rolling and there are test parts under that body.

Hi, I looked at some photos of the Xfactory car and The dogbone angles looks no different to other 2wd cars. Toe-in, antisquat and low roll centre can be found on other 2wds also. But the chassis seems very stiff. Something you dont want on a medium or low grip track. I bet that mm car with a softer chassis and the motor even closer to the rear axle will create even more rear grip than the Xfactory car.

afaik you can contol flex like the xray flexpoints by removing screws from the topdeck.

i just can't understand how a driveline with more resistince causes more grip... so basically i remove all ball bearings and can drive with drifttires

aeRayls 07-21-2013 12:35 PM

Another distinct advantage to MM is when you use 4 gear tranny. It significantly increases "control" of your car. Throttle inputs affect the car way more.

Only Maifield has kept his car from being photographed. There is a really clear picture taken over Lou's shoulder of Cav's car with the body off.

I have no idea what the centrino looks like so I don't know what I'm looking at. It has saddle packs facing front to back to thou

Look at it yourselves. It's on LiveRC's site in the photo gallery

Read somewere that good old dogbones creates more grip than cvd`s because of the pulses it creates, letting the tyres find grip before the next pulse. I know its like that with motorcycles. Single or twin motors creates more grip than a 4-sylinder motor because its longer between each "bang".

@aerayls: do u mean in air or on ground? And do you think a mm car with only 1 idlergear would be slower than a rm-car?

racer1812 07-21-2013 01:02 PM

I applaud X-Factory for what they can do as a small company in comparison to the "big 3" but like I said, if it really is that good on a lower bite surface I would think someone (AE, K, or TLR) would have put more effort into a MM only car and not the convertible cars we've seen so far. And I think they would have done it along time ago.

Kyosho's newest car..convertible
TLR...convertible
Durango..Convertible..............along with multiple knock offs being convertibles

AE.............only time will tell I guess, their new car will tell us all what they feel is the best on both low and high bite tracks. If it's a convertible AE engineers feel RM is still better for low bite, if the new AE car is MM only then X-Factory can stand up and proudly say "We told you so"

all IMO;)

In the air it's especially noticable. It also has to have some effect on the ground because of the weight transfer it creates. Basically a 4 gear MM is the only way to go.

Cody227 07-21-2013 01:45 PM

So maybe i'll need the c4.2 gearbox for my mm-chassis... I'll post some pics tomorrow

I still agree with you. I'll say that I was really surprised how much the x-cars had come since I originally drove Paul's years ago.

All the newer cars are convertible simply because it makes since to design a car you can produce a handful of extras for and make it RM or MM. That still doesn't mean that one isnt compromised or couldn't be made better/faster if it were a car made soley around one style or the other.

If AE were to make the B5 only a MM(won't happen)... It's be really hard for me to run it lol... I love my current car.

I'd much rather see a new RM car designed with a conversion kit sold seperately for MM.
