If you mean it is faster in a straight line then maybe it could be possible in terms of rolling resistance. But last I looked most tracks have corners.

Do you race/drive a G4S wally?

Oh, and by the way, with my dumb way of setting up a car as a 4wd, I TQ'd and won round 10 of our championship - dunno how that happened!
lol im just saying that with some driving styles the car works better when you dont over drive the front.my friend drives a g4s and he drives it like this and it dosent matter what car you drive setup is setup and all these cars work very well.i dident say your setup was dumb.

I wrote a big long reply - but I think it is just wasted so I will leave you to your own ideas, wally.

Default Steering!

Silly question time... I am about half through building my G4S, the front end is complete and as a result have a question for you all.

I have noticed that when i have the steering tie rods attached to the steering system it doesn't move as much it does without any load on it. Have i done something wrong or will it improve as the steering knuckles start to free up etc?

Look forward to reading your replies.

Follow exactly like in the manual. The servo horn for steering is different than for throttle/brake. It is like that.

Assuming that you still have enough thread left on the ball, you may add 1mm thick shim on the steering bellcrank to reduce the steep angle from servo horn.

Not necessary but worth to consider. A drop of CA is good idea to make the ball connection almost permanent.

i have thaught long and hard about the overdrive theory. (man my head hurts) , all i can see are advantages, to a point where the rear tires are smaller than the front. i agree this is to even out tire wear, but also i can see an advantage when a oneway is used, that the front of the car when being overdriven (small tires as well) this would also help in the front pulling the car around the corner, may start to push a little untill the tires are even in size or depending on the size of the overdrive, just slightly smaller than the rear. but i also lost (in a self inflicted accident) my side belt, all the car did was oversteer even on the slightest bit of acceleration. i dont see any advantage in making the cars like a rear wheel drive. if they were made rear wheel drive, there wouldnt be a problem in designing the cars in a better fashion to accomidate steering servos and weight distribution. so i like my G4 , and G4S being 4wd as they need it due to the power of the engines these days. this maybe a waste of time Zoom, but i have a little bit of it at the moment to spare.

You can reverse the car much better than anybody else with bigger tires at the front and smaller in the rear.

( don't do it , I'm j/k )

disregard the rear wheel drive stuff. but by running the overdrive, with a oneway, will this help the car pull out of corners and help the ease of oversteer ?

I hadn't got to the servo part yet... i was more talking about when you connect up the tie rods up to the steering knuckles and how it doesn't look like it turns as much as with out any load on it at all (steering system) that is

maybe it is nothing... but i had to ask

i think this is geting out of hand,i run a 1mm split,if you run overdrive you run a 2-3mm split on a big track overdrive will help,on a small track it dos not.

Wally: what are you overdriving ? front or rear ? and the 1mm split ? front smaller, or front bigger ?

Bundy : it might be the ball cups ? when they are new i found them pretty tight. they will loosen up. but i wouldnt get the pillow balls too tight, servo might not find center perfectly, just a thaught anyway

See what I meant Patto, Wally was never going to understand. Big track, small track, makes no difference.......sigh. A car that drives the front more than the back is easier to drive but will be slower overall. When we talk about overdriving the front, it is then compensated with tyre size so the net effect is 1-1 drive. It is all about car balance and the roll centre will be lower on the rear with big tyres. This is the benefit of the overdrive theory. Also, tyre wear will stay in the sweet spot longer with overdrive to the front....I know this is still going to be wasted on Wally - since he doesn't even own a G4S.

Anyway....

Bundy - I agree with Patto, the ball cups are tight and will find their own groove once you run the car a little. I'm sure since you've had pillow ball cars before that you haven't bound up the pillow balls so it should be nothing to worry about. If you find they don't free up enough, just sqeeze them with some pliers while the ball cups are attached to the balls and this will loosen them a little.

Cheers,

Mike.
