Today I picked up a controller for my Keyence Tachyon ESC and Luxon KG motor setup.
I can gain access to more settings that the stupid button combinations on the ESC itself.
It just makes sense and its easy to use. Just connect the RX cable.
I got the SR (shine Red) because it should be easy to find in my RC box. Also came with a reflective strap.
Manual is here.
I'm going to be putting together an option set for purchase so stay tuned. The best from Japan!
