The Bristol's gun configuration was also changed for the online version. As I recall, the board game had the Bristol with 2 rear Lewis guns making it an even tougher plane to fight. The compromise on youplay was to change it to only 1 rear gun but not a lewis type. Perhaps a compromise could be reached with the N17 as well. Perhaps give it 2 forward guns but reduce its stability to a C for the 2 gun version only.
