I have project I am working on using a TRX4 chassis, and I would like to use the XL5-HV ESC I have sitting on the shelf. But, this project is somewhat unique, and I do not know if I will be able to mount the ESC where the button on the ESC will be easily accessible. This is not the first time I have had this issue with a build, and has forced me to look to other brands for acceptable options.

Suggest doing one of two things with Traxxas ESCs...
1. Install a port allowing for a remote on/off switch.
2. Be able to program it to an always-on mode, so that when the battery is connected the ESC automatically turns on. For the most part, this is how I run my Castle and HW ESCs.
