I don't know much, but shouldn't he try removing his front steering post to get rid of push?

One thing that gets me confused is the differing opinions of what helps eliminate understeer/oversteer. I would've thought stiffer front springs would give more push?

Rubber tire is a different animal some times. Forcing the tire into the ground often helps. Overtime you start to pick up on if the car is rolling too much or not enough. And the painful trial and error method sometimes is the best way of figuring things out

we really need to be clear what we are advising

foam

rubber

carpet

ashpalt


as all 4 work differently, something that works on asphalt won't necessarily work on carpet, etc.....

It depends, a stiff spring can cause the front tires to over heat a few mins into the race which will make your car push

Default Battery wire routing

I want to ask you guys how to route the battery wires on my T3.
It's the first time I'm building and wiring an electric car and I can't figure out how to route it like I've seen on the redrc pictures and such.

Most have the wires running beneath the top deck, but on my car there is absolutely no room for that with the lipo stops in place.
Is this because of the battery, it's a IP 5000.

Here are some pictures:




I don't like routing it across the top deck because of the drive belt, I'm afraid it will start to rub and may cause shorting the electronics.

Route the battery wires above the belt, keep them long enough so they loop over the top and you wont have any issues. Thats how I run mine

Hahaha Mike to bad thats two different chassis and layouts.

Anyhow unless you have your battery pushed out, on the stock chassis I used the nimh plastic cell plastic pieces and it will make your battery be on the edge of the chassis. I run my battery that way so you dont need weight to balance the car, or not as much. And your wires will fit inbetween the top deck and battery

Hope that helps

Ok, thanks for the help guys, will try to move the battery more outward to create a bit more space for the wiring.
And then add the weight to the middle of the car to get it up to 1350 gr.

As a last resort I can always route the wires over the top deck.

Default Routing wires

I route the wires over the belt but I made a Lexan right angle (bodyshell offcut) about two inches long and superglued it to the top deck.

Xray makes weights that move the battery off the chassis alittle father. This is what you need. You need to move the battery out as far off the right side of the chassis.No need for weights in the middle of the car. Make sure wires are long enough to go over the belts...you'll be glad you did. Also try the gear diff made for it. Will give you more acceleration and more steering too. GL

Okay figured the push subject out, it was not so much the push it was the steering locking out.

I put the ackerman back to one, then worked my epa on the steering to have a constant arc from off throttle to on throttle so there is little difference.

The final touch came down to some body testing, and traction compound.

add3/4 instead of 1/2 in the front, then switched out from the team titan altis body to a mazda 6 team titan which was better, then finally switched to a mazda 3 also team titan which had a longer body, the perfect body for the track.

Managed 26 laps finally in 5:11 with 3 mistakes in the run, and some over shooting in the sweepers. 11.9

I think 27 is manageable with some more practice time on the track.

Current racers have achieved this so have to catch up on them....
Best Record was 27 laps in 5:02
Best time was 10.9

Here is the updated setup sheet
