I'm in a similar space. My neighbor bought a $2k scaled WWII boat he wants me to build the controls for i.e., rudder, motor, turret position, turret firing of ball bearings, "radar", etc. All was well within my scope of an arduino head-end- until he mentioned FPV cameras on the turrets. After doing some research, the arduino is only capable of 3-10fps of streaming. After knowing only the tip of arduino coding iceburg, it seems I'll need to learn yet another language.
