THROTTLE and Steering SENSITIVITY IMPROVEMENT FOR THE ZD RACING EX16 (AND OTHER CARS)
Like many ready to run RC cars, the ZD Racing EX16 has terrible throttle and steering sensitivity out of the box but. The good news it is very easy to fix as you'll find in my brief guide below.
This is the first of a 3 part series of tuning guides for the ZD Racing EX16. The others can be found here:
Hobby grade RC cars have proportional steering and throttle meaning the amount you squeeze the trigger or turn the steering wheel is reflected by the RC with a proportional amount of motor speed or wheel turning. In theory that is. The ZD Racing EX16 is poorly setup from the factory which, to be fair is the same of most cars but it's really easy to fix with the dials on your transmitter.
Improving the throttle control
Precise throttle control makes the driving experience so much better. A poorly setup throttle can cause the trigger to act more like a switch that the throttle control and this is exactly how my EX16 was when it arrived. This made it spin out easily even when in a straight line and is practically impossible to drift. Check out below for the fix
That's it. Now you will only hit full throttle at the end of the trigger travel meaning everything in between is sweet, sweet proportional control giving you much more room for getting the throttle dead right during cornering or other manoeuvres. If you want to improve this even further you can drop the throttle dead zone from 9% stock to 6% using the racerstar programming card as detailed in this guide.
Improving steering control
This process is similar to the throttle but is mechanical rather than electrical in nature.
You're done! Mark it on the dial and now you will have steering in both directions right to the end of the steering wheel travel meaning again that everything in between will be proportional.
These are very simply improvements that anyone can make and all they are really doing is making best use of the controls that are given to us. The improvement they make though should not be understated - I went from spinning out even in a straight line to a much smoother and more controlled drive.

Hi, thanks for the tip! I also find by resetting the controller can eliminate the throttle problems. my controller came with throttle percentage at 75% out of the box. After resetting it hits top speed at 100%.
