I´ve been browsing the flitsservice.nl site for a while and came across a modification that should increase range:

I´m keen on trying it on my V1, since I often run into highway photo radar and 700 feet sometimes isn´t enough when doing 140... Supposedly increases range by over 300 feet. Maybe flitsservice.nl will chime in to explain the details about how it works.
