Thanks for the info about how exchanges work, makes sense.
Recently my transmitter settings got tweaked by accident and I lost full throttle, and because I didn't understand the LEDs it took awhile for me to figure out why my car was just a touch slow. So I've been trying to make sense of how the LEDs light up during normal operation of the GTB. What I observe is this:
Drag Brakes Enabled:
"on": Blue + Amber
push brake: Amber
No Drag Brakes:
"on": Amber
push brake: no LEDs lit
In both modes:
neutral: "on" + Red
full push brake: "on" + flashing Green
part throttle: "on"
full throttle: "on" + Green
This sort of makes sense except it would make *more* sense if, when you have drag brakes enabled and are using push brakes, the Blue LED were lit rather than Amber. Then push brake would equal "on" minus Amber, in both modes.
Is there some way to interpret the GTB's LEDs that makes more sense than what I've come up with?
