How do you increase the roll and pitch speed.(I have an idea how to but I don't want to mess things up)
Are you asking about the banking speed or the banking max angle? Are you already flying in Rate mode or still using Attitude?
Stabilization -> SettingsBank# -> Advanced
Enable the "use advanced" each time you go to this page. Adjust:
AttitudeModeResponse to change max angle in Atttude mode
RateModeResponse to change the banking speed (rotation rate) in Rate mode
MaxRateLimit to change the banking speed (rotation rate) in other modes (not Rate) such as Attitude
