Default How to get a Silent ESC for outrunner motors

You can use any BLHeli_32 ESC which are designed for quadcopters.
The one I use are made by Airbot and cost around $12 and are 35A but you can find some that are 80A which is enough for crawlers, If you have heat issues you can probably glue on a heatsink but I have not done so.

These ESC's Usualy do not come with a BEC so you need to get one of those. I usualy use battery powered servos so I get tiny $2 BECs that are adjustable voltage to power the reciever

The default configurations do not come with Reversing so you also need to shell out some money for an Interface that connects to your PC, I use a Noxe F4 flight controller which has a usb plug, but you can also use an Arduino Nano or a ton of other devices. Connect the Ground and pwm/signal wires to the interface device and start BLHeli suite

The Items with a little green house are the settings I changed.
The musical notes play on startup and I chose the Dukes of Hazzard General Lee Horn, which I found on YouTube. You basically copy and paste the code.

Non damped mode: is your active braking or freewheeling.
Bidirectional 3D: is your reverse.
Rampup power: is like punch but so is maximum acceleration, so IDK
Low Voltage Protection: is untrustworthy so set it High and hope for the best, Check your batteries imediatly after use, Quad pilots don't use this or their crap fall out of the sky.
Brake on stop: is your drag Brake
Throttle calibration MIN, MAX, and CENTER this varries I know that spektrum is 1900 for max, 1100 for low and 1500 for center, you can also use the throttle auto calibrate by holding full throttle while power up, but I have never done this.

This Is how I power my SCX24 but I have also used these 35A ESCs in my 10th scale crawlers although it was with different firmware.
