It’s mentioned in the owners manual, but nowhere in the setup sheet or a choice within the programming box.

Am I tilting at windmills with this ESC trying to find a Blinky mode?

I’m sure there’s gotta be some knowledge out there. Thanks.

If it is the 1S120, then check the ROAR list:

ROAR Racing

"Red LED, .19 seconds/flash. Non-Timing: Use program box to set boost timing and Turbo timing to zero."

It is indeed a 1s120 and thanks. I had thought I had done those setting changes, but I'll look again.

1/8 pan car, eh? We're running them again in Toledo, Chicagoland, Cincinnati and a few other US locations...

Some programming boxes make changes to the ESC immediately (when you change a value), while others require a separate action to save all changes made in the current session to the ESC. I don't recall what the Toro does, but it's always good to double-check.

I had considered making some road trips to your neck of the woods to run my old RC300 again (and I even bought a new engine for it), but life has gone a different direction for me, making travel difficult.
