Hi, I have a new rig and it is harder to control at faster speeds. Turning to jittery or spins out. Have adjusted trim. Wonder if its just weight, tires and motor torque. Running the RC on 3S. I don't have the same problem with my Typhon grom BLX. Any thoughts if adjusting the front end turnbuckles would help or maybe Something else. Thanks for your help
 
I would suggest experiment with different weight shock oil.
Tires would definitely cause an issue as well.
If your shock springs are a bit too stiff that would make bounce around more than we like.
 
How does it handle on 2s?
I had a small 1/10 DeeRC and with 3s it was cartoonishly fast!
The stock shocks were 100% useless and were replaced immediately.
Is your 3s battery oversized for the car?
Is the motor still stock or did you upgrade it to a larger one to make it '3s'?
When I put the 3800kv motor in at 3s, it was much heavier because all the electronics were different, bigger than stock.
If I strapped my 9000mah 3s battery to the roof of my DeeRC it would have been real fast but balance and weight would have made it impossible to actually drive.

Making sure the steering and suspension is adjusted correctly is always a good idea.

Like @Tunedfrog said, tires are huge! Make sure you are using the right ones for the surface you are running on or spin outs will be common.

I've only tried the 3S battery that it came with. maybe I could just turn down The steering Adjustment to reduce steering radius
 
It's a tiny budget buggy, so I wouldn't expect wonders at full speed...

It can probably be set up to handle better but it's gonna take time and experimentation unless you find a good setup sheet, online which is unlikely.

From what I saw in a video, the shock oil is THICK. It takes a second to return to ride height after a drop. Weird. Does it handle like this guy's or worse?

Setting your end point down could help but dialing the issue in and getting the car to hook up at speed and handle turns is better.
Did you do a radio calibration on this car when you set it up? Ever recalibrate?
Strong fresh batteries in the radio? No chance some interference might be causing this?

The battery it came with is prob correct so theres that.

Do you have a low voltage alarm?
Sometimes the motor will draw on a battery so much that it makes the steering misbehave.
Battery sag.
You might gave that going on. Esp if the battery it came with is junky like my deerc... mine was undersized from factory too.

Thanks for your input. Do you have any suggestions for a low voltage alarm for a small rig? I also realized after I just came in Running the RC That it Doesn't have a gyro And this is why it handles differently.
 
Thanks so much.

Any time! Did you look into recalibrating the radio at all? Its like resetting the system. It might help.
The other suggestions about shock oil, setting up the suspension, tire swaps are really good ideas too. Have you had any luck there?

Another thing I should mention... cars break, pins and rods bend... its important that you really look your car over for bent shocks and bad bearings... any broken or bent parts could cause crazy handling at speed. Look for missing hardware too. I don't think its your problem but you could inspect the servo arm and teeth to be sure they arent stripped.
Make sure things spin free and smooth... check the diff and trans carefully.
Pulling any RTR car apart to fill shock oil and diffs, relube everything is pretty common. This seems like a good time for that to me.

I would def spend some time cleaning and inspecting your car.
Its free and easy too!!! 😎

Does the battery say what Mah it is? It might be undersized too. I think my DeeRC stock battery was 1500 or 1800 mah. It was like a transmitter battery at best. 🤷‍♀️

I’m now thinking as I compare its drivability to Typhon Grom BLX, that it probably has something to do with no Gyro on 12XS. One youtuber thought extra weight helped but I had much better stability and not so skiddish is turns where RC would spin around and likely due to no Gyro. All my other RC’s have Gyro’s. Old ones don’t but they are not as fast as the X12. Bet your suggestions would help it too. Just my thoughts.

I inspected shocks, etc for bent parts and didn’t see anything obvious thing. The RC is new with four runs and no crashes yet. What do you think about toe-in the front wheels a little? Also, the RC is heavy due to metal chassis and wonder if this is good for turn stability but maybe the wheels are unable to hold in turns. I can control car in straight runs, but rc rc responds to fast from transmitter and over steers in turns. Maybe I just need more practice to handle a non gyro RC to control it better
 
I'd bet it's the last thing you said :)
4wds usually have slight toe out or rarely straight in the front... Never seen a 4wd RC with toe in 🤷

Anyone know what diff oil to run in the X12S? Mine handles perfectly and the steering is great. It has no gyro and it goes in a straight line on asphalt better than any other RC I have.
