That's pretty interesting Don....both the flash mod and ultra sonic battle. How could this be possible on a mobile vehicle though? Instead of frequency response, the units would respond to vibrations or vibrations of the vehicle......that is, if the sensor is set to respond to so many pulses per designated kilo/mili/micro/nano/etc... seconds. Sound's like some expensive hardware and chips in your future, but that would be an interesting project to see!

Those towers are for those who want to use them in official battles. Nothing says you can't gut those towers and place the sensors in known weak points of the tank. I think that would be best, in my opinion. Reroute the IRreceiversto go in known weaknesses of the tanks.<br type="_moz" />
