I would say I have gained some knowledge - about the VESC settings (and this definitely beyond the channel changing). The settings you are referring to are remote specific and therefore if they are available would likely be found in the remote receiver firmware/software.
In my humble opinion, however, the buttons are good as is. It’s actually quite natural to just press down the stick when you get it where you want it. Having to press “B” would mean holding the remote differently (for me, awkwardly), and what if you accidentally also pressed “A”? Or just had your finger up there and pressed “A” long enough to turn it off? Not a good idea as far as I’m concerned.
I posted my results in the First Batch Problems & Solutions thread, along with a couple videos. I definitely recommend that anyone not 100% happy with the remote check out these settings and make appropriate adjustments. Just changing the settings by .1 made a HUGE difference!
I’m happy to help you if you want.
