glad you got it figured out
the reverse delay can be a good or bad thing... depends on what you are used to or want to do...
I prefer no delay, but with that you can run into issues with stripping gears and stuff by going from forward to reverse without stopping...
My friends truck has an ESC that you need to double pump the trigger to go into reverse, if you just pull back all you get is brake. I don't like it, but you do kinda get used to the way it works after a little while...
