    Minium speed for VHL-3s

    Hi there !

    I'm Sergio, I would appreciate some help.

    I bought a Traxxas Slash 4x4 and I wounder how to set the minium speed of the car.

    I'm working in a new prototype of Autonomous car but this car is really fast !!! I know you may enjoy it but I would like to reduce it! (more than the 50% of the trainning mode).

    If it is not possible, no problem I have other ESC which can reach my goal, but I think there should be some way with VHL.

    Thanks for your time !

    I don't think you can see a "minimum" speed. However, by installing the Bluetooth Link in your Tx, and the Traxxas app in your phone, you can change numerous settings, including the "maximum" speed of all three (normal, race, & training) driving modes.

    Welcome to the Traxxas forums!

    If going for minimum speed, do as Panther mentioned above, change to a smaller pinion gear, and upgrade your motor/ESC to a sensored system.

    Good luck, keep us posted, and have fun!

    I wonder if you can set your throttle EPA at a very low point to achieve the low speeds you are looking for...

    It depends on what you mean by "minimum", and what you want for a maximum, and are you going to maintain this speed.

    The VXL ESC is pretty good for RTR, but it has its limitation. If you are looking for sustained speeds less than 5mpg, you will likely see cogging and jerky performance. Sensorless systems like the VXL do not do well going slow, so you can either go with much smaller pinion and much larger spur, get a brushed system like the XL5, or get a sensored brushless system.

    I vote "sensored brushless"...and Hobbywing.

    Brushed is better for slow speed and alot cheaper as long as you don't have an interest in going fast later on.
