I am currently planing my first build and am a bit hung op on the choice of remote. I’ve read tons of reports here regarding the reliability of different remotes and their “fail-safe” behavior. Most people seem to be happy with a remote, which will send a neutral throttle signal to the ESC in case of a fault. This is obviously better than jumping abruptly to maximum braking, or repeating the last signal.
But I live an extremely steep, urban area. Going down a 20% slope, the remote crapping out, and setting the throttle to coasting is just as bad as a board jumping to full throttle on flat ground. So the best fail-safe behavior that I can imagine would be if the board slowly starts ramping up to maximum brake current. As far as I understand, the VESC firmware already has a fail-safe feature, that can be configured to apply a certain brake current. But for this to to work properly you need:
- A remote, whose receiver will STOP sending signals to the VESC all together. Not neutral, not reverse throttle.
- A slow ramping of the braking current to not simply throw you off.
I’d appretierte the input of the more experienced builders here! How do you set up your fail-safe? Does this controlled braking type of fail-safe exist at the moment? And yes, I am aware that there are very reliable controllers out there (GT2B etc.), and many of people will have the urge to reply “I’ve used XX remote it for XY and never had an issue”, but I still think it is worth discussing such a crucial safety feature for something as dangerous as an electric skateboard…
