Hey Michael, the unit comes from rctankelectronics (aka tankbear) known as a vampire many in the club like them. It's basically 4 sensors and 4 leds on a wiring harness. In this tank there are 4 vision slits on the cupola, which is where I put the sensors. The indication leds were put into the cupola and sanded flat so you can't see them till they light up (or you look pretty closely).MichaelC wrote:tom, do explain ! Is this hidden battle unit business a DIY ? I didn't think the Tamiya JS-2 came with anything different than all their other offers.
Installation at the time of construction is straight forward although retrofitting in the same way I did would be a pig of a job.
