Well, I guess Ill jump in now,

Matt, you have noted many, many, times the success with your JetCat speed limiter. You stated that it has worked for more than a 1000 flights. I was just wondering what the indicated versus calibrated speeds were on the models that you have !QUOT!tested!QUOT! for those 1K flights. To say that it worked is really saying that it hasn't caused a crash ...yet. You don't really know how fast you really were flying. How often should we be required to calibrated these systems? And what about the liability to the Mfg. when it is determined through video that the model that hit the bus load of nuns was actually doing about 207...or so? And we rely on the limiter to keep us in strict compliance with the AMA insurance limits. I realize that we have some sharp guys in this hobby, but ponder this. A few years ago an airplane builder named DeHavaland of Canada who has been in the game for quite a while, designed and built the!QUOT!next generation!QUOT! turboprop called the Dash 8. What does this have to do with jet modeling? Here's the connection. These guys at DH put the pitot tubes and static ports exactly where they should have been according to years and years of experience and testing. But there was only one problem...the system was highly inaccurate. So the guys with the pocket protectors and TI calculators spent months and $250,000 (that's U.S. dollars) redesigning the WINDSHIEL WIPERS so that they didn't interfere with airspeed readings. I'm not an engineer, aerodynamisist, or hell, even Canadian but I don't want to think about installing the system.

Now let's just say we iron out the accuracy issues. If we want to limit the speed to any value, why don't we do what the auto industry does. Give us or require us to carry an airspeed indicator just as tp777fo mentioned. It could be configured to sense the speed and then transmit an aural warning telling us to either look for the cops....Uh, I mean pull the throttle stick back or pull up or both when we approach the limit.

I don't want another failure point in the airplane. No speed limiter of any design will eliminate a crash of any kind...period. It's up to the pilot to maintain 200 or less

Enough for now,


John
