Ever since I had the major shunt (dead car on main straight) I had been getting these occasional glitches which was getting worse as time went on, but I had noticed when trying to cycle the battery pack that the voltage was fluctuating from 8.4v to 4.5v, and whenever I touched the pack it would trip out on the charger.
Turns out that the connection tabs to the top battery (the one with the holder around it) had come disconnected and was only held in place by the shrink wrap packing.
Having now resoldered the tabs the glitches have now vanished.

Maybe those in the earlier post who have had glitching problems should check the tabs on their battery packs.

I see there are 2 different roll bars for the rear can someone please explain the difference between the std G4 Alum. Rear Anti-Roll Bar and the G4 Rear Dual Adjustable Anti Roll Bar?

Thanks,
Mark

Car Breaker-the front wheels will be driving the car faster than the rears. The car will push.
thank, no wonder my car is much easier to drive now, the place I run isn't prepared track. I can ease with toe and camber now.

but how come my friend still say my car is oversteering? is he simply using the wrong word? (he is damn alcoholic )

Understeer (Nascar term - Tight)
When the front pushes (slides out) in a corner
Car not wanting to turn

Oversteer (Nascar term - Loose)
When the rear pushes (slides out) in a corner

This causes a lower roll center in the rear of the car. This helps in gaining rear traction if your looking to gain rear traction.

Here is your setup developed on an electronic data sheet. I'ts very interesting to see how you changed the internal drive ratio from stock 2.526 to 2.667, and actually your drive ratio front to back is close to 1 but not close enough. To do so you would have to shave your rear tires a bit more (62.22mm).

Default Did I tweak my chassis?

I had a bit of a radio problem my first time out with the car, and clipped an overlapping 2x4 fence that was laid upside down. The impact broke both left side suspension arms, bent the stinger and dented the pipe where it hit the pulley.

I checked the pins and they rolled smoothly. The chassis (complete car, not bare) did not rock when I set it on a flat surface. I put the car on the set-up machine and adjusted the suspension angles. The last thing I did was to put the car on digital scales. I had to put 1 1/2 turns in the LR spring and 2 1/2 turns in the LF spring to get the following weights;

LF 360.8 gr. RF 389.6 gr.

LR 437.5 gr. RR 438.4 gr.

I can probably do more adjusting to balance the car, but if the chassis is tweaked, maybe it should be replaced rather than chasing a problem.

Your comments/advice requested.

Default Thanks for the input afm

Yes I would have to take down the rear abit more. I normally run a car with a 1mm split between front and rear tires. I just like the feel of the car that way, but you are quite right in your analysis.

Ray, do you have the G4's Electronic Calculator Sheet??? I can e-mail you a copy. Just tell me were. I don't know how to upload it here.

bimmer
you need to set the car on the table and lift it up from the center at each end of the car and adjust the front springs so both rear tires touch down at the same time and adjust the rear until the front tires touch down at the same point
also a crirical thing on a g4 is to make sure the front sway bar is totally seated in the holder. if it is not it will cause you tweek headaches. if your bar adjusters are not level or close to level the bar on the front is probably not fully seated.

are there any steel pinion gears available for the G4?

i have the aluminum gears which are ideal for national etc meetings (reduced rotational weight) but for the club meetings i would like a set of gears that do not wear out as quick. my 18tooth gear now has knife blade edges after only about 2.5 hours of use.

i know i have a g4e but the gears are the same/simular so i thought a posting in the latest version of the car would get a response.

From my opinion, the KFactory gears are the most durable in the market. But if you think the G4 gear wears too quick you have to try Kyosho one
