I fixed my nano-x remote, one issue was with the crystal, and the second with the On/Off switch of the transmitter.
I resoldered the crystal, that helped a lot, but still it was not reliable enough, sometimes loosing the binding when i only touched the switch or just shake the transmitter. So i swapped the switch, now it works well.
We already had discussions about a kind of cruise control, with analog or digital throttle in combination with a dead man switch on the remote, which you need to hold while cruising.
I do not know why, but i somehow ignored benjamins videos too long. So the solution for these features is already ready! Have a look:
Nunchuk VESC control:
I will definitely upgrade to wireless Nyko Kama nunchuk which is widely used for the nintendo wii and in the ESK8 scene. Note, you can only use it with the VESC, which has a special input and code for the receiver.
