True, but busting out a netbook, hotwire, pulling the throttle plug, starting the netbook, starting the program, plugging everything in, navigating to the setting, changing it, applying it, shutting down, disconnecting, connecting the throttle back up, then swapping pinions vs. just swapping pinions and pushing a couple buttons a few times... Big difference.

Your answer above will work (being able to set it to any of the existing modes at will from the buttons). I can't show off my blinking esc without a netbook (that I don't usually carry), but club racing (where there is no tech) is almost always on the honor system anyhow.

I could see this making pre and post tech at some bigger races a headache. Imagine someone coming up to the table that doesn't have the netbook/hotwire, doesn't know anyone that has one, and the tech has to check that it's in the right mode manually or find someone that can change it (then, potentially, check it again after the race the same tedious way)...

At the least, there should be some simple one-way method (cannot be reversed without a hotwire, just like you can't configure your C1 and C2 without one) to change it into the locked blinky mode with some basic dance like holding both buttons down before turning it on, then it is set after 3-5 seconds if the user keeps holding them down.
