MHSFA Grass-Roots Timing System
May 5, 2016
Fellow speed freaks,
Â
My "grass-roots" speed timing system is now complete and ready for its first real world test...I've been working on this one for a while now and have finally gotten to the point where I'm confident that it'll get the job done.
Â
This is a chronometer-style system that uses two timing triggers that are actuated by people sitting at either end of the speed course. A so-called manual system, it still suffers from human response time, but unlike the complex and expensive automated systems, it is very reliable and will work every time.
Â
The purpose of this project was to develop something that any person or club interested in speed flying and competition could replicate for under $100 and be confident that their final speed results were comparable to others. Hopefully this will help grow the discipline by lifting a major hurdle in the eyes of many, that being timing system availability and ease of use.
Â
First real world test will be May 13-15 at our local PNW Othello fun fly. We'll time anyone who wants to run the course and I'll also be doing direct comparisons to the GPS-II data from my speed helis.
Â
This system will provide run time and associated speed through a 200m or 120m course with a simple switch used to select course length for speed calculations.
Â
Not only will it display this on the on-board LCD screen, but it can also be connected to a laptop computer via USB and will display the times and speed on a simple GUI so that the event participants and spectators can see results in real time.
Â
It also has LED's that indicate when the model is in and out of the course so that status can be announced over a PA, if desired by the event coordinators.
Â
Stay tuned for more details! :) - Justin
