I wonder how the speed is captured? You'd have to put your photocells directly on the tarmac. At 100 m/s, the vertical tail fin isn't large enough to trigger a circuit closure in an average photocell, even with the potentiometer settings maxed out. At half a meter long, even the entire fuselage would still be a mighty small object to capture with a photocell at that kind of speed.
