Limitless Limitless first run

[TimGoheen]

I finally got to make some good passes with my limitless. 99,101 and 103 mph.
It is a stock V2 chassis and tires with perfect pass springs. The motor is a castle 2028 1100kv. XLX2 esc. Futaba gyro and 8s batteries.
Gearing is 39/39.
I'm looking for some advice to make it run faster and straighter. Open to experienced advice.
Thanks, Tim

Post a data log.

+1. Also, which batteries are you using? And what was the distance traveled?

You should post this in Speed Demons, that’s where all of our resident speed runners post. There is a massive amount of information there. Welcome to the forum!

From the esc or from the gnss ?

How can I move it there ?

From the ESC. You can pull data logs from your ESC by the Castle Link and download them. Gives tons of info, can really help you to fine tune your setup and also help with your technique.

I’d just start a new thread. You’ll have several people help you out. There are several stickies there as well with some great info.

The ESC datalog will let you know if you're too aggressive with the throttle input and/or Lipos can't keep up with burst and will certainly decrease your top end wall.

A futaba gyc gyro can help the car stay straight.
Make sure you balance the tires.

I downloaded the data logs, but I can't seem to find them in my phone.

Does the Spectrum DX3 ce with a gyro built in?

The DX3 is a transmitter, not a receiver.

The DX3 is compatible with Spektrum gyro receivers.

Go very soft on the throttle, use all the distance you have. Grip is not the accelleration limiting factor but power demand (motor/battery)
No sudden increases accelation will also keep the car much better in line.

Balance the wheels, indeed. I haven't used the perfect pass springs myself, but the rear should be really stiff
DX3 has no steering expo settings, so be very suddle with steering when correcting.

You can increase your pinion size a lot more. 1100kv on 8S is still on the low side, but perfect for getting the car dailed in and grow some confidence.
Starting on less cells like 3/4/6S lower/less leathal speeds and tune those first, does also help to grasp what speedrunning is all about

Also worth noting the Spektrum radios have terrible range and rarely get used for speed runs unless you get a signal booster for it.
