Does anyone have information on the Aircraft Speed master system made buy RC Research and Manufacturing.

Hi Mike,
Wahat do you need to know? I have a set of Speedmaster speed traps that I purchased from some pylon buddies several years back. They are sky staring, light-activated sensors that measure the speed of objects traversinga verticaloptical plane. There are 2 sensors, spacedafixeddistance apart, and are triggered by a passing object such as a model aircraft. The elapsed time between the sensors is measured, calculated and displayed in real time on a hand helddata unit. The speed range is 7-499 MPH or the KMH equivalent.It takes about 15-20 minutes to set up-generallyalongside the runway edge with the data unit at the pilot stations. The whole set fits inside a typical tranmitter case. I brought my set to an early season jet together at the N. England Jet Club site last year andcan bring them again to our late April event or Plum Island in June.
Let me know if you need anything else.

Art,
That would be great if you can bring them to Westover and Plum Island. I was looking to purchase one. Do you know if they are still avalible and if so whare can I get one?

I've had several PM's on the "Aircraft Speedmaster" traps and thought I'd post some info to any interested parties.  These speed traps were manufactued and sold by: Roger JONES, RC Research & MFG, 550 Primrose, Odessa, TX 79765, phone in the US: 915-550-2413.  If anyone retains issues of RCJI magazine, a review article was published in the June-july 1994 issue, pages 22-23. The SpeedMaster price at the time was: $ 495 USD plus shipping.
