2.1 EX with stock.
Hey Guys.
Just trying to update my new 2.1 EX esc. Will it run with the newish 528 stock update or only the 205 mod software. Have done the update on the esc and then when connecting to the LCD box it says the software needs to be updated. Got a large race meeting this weekend and am only running 10.5 v3 motor so need stock profiles. Any help will be great.
