I’m currently working on a rebuild of the hobbywing lcd controller to make a controller better suited for my big hands. it’s pretty doable but I don’t want to be constrained that much by the pcb layout of the original controller.
The main question: Are there any arduino or stm based options to control hobbywing esc’s other than the original hobbywing
Negative shipmate. They are only for themselves. Selfish bastards. 
damn 
Well I guess if your using the guts of it you can print whatever you want. Or get creative with something else… Make it yours. Lol
I’m already planning to replace the hall sensor on a spare controller with a controller joystick (restricted in one axis) to make it easier to change the location of it.
same with extra dip switches, I even could use the dip switch in the joystick to reduce the amount of buttons to work into the body. The addition of an extra dead mans switch is also an option I’m lookin into.
Are there other options on remotes that you would recommend looking into?
Nope. You sound pretty smart.
