Snap Switch

[ronlock at comcast.net]

Quite right on the judging difficulties Gray.

About switch timing- Seems like I heard that the early 
Futaba 512 PCM had a timing capability, that was
subsequently dissabled.  Anyone confirm that?

Such timing functions are not legal according to pattern rules.

>Good Point, but unfortunately judging snaps is difficult, and then educating all the judges is even more difficult. Having the nads to zero people due to "not real snaps" is also difficult.  Even the people who have said nads for zeroing an Advanced flyer may exhibit shrinkage when it comes to zeroing a top level FAI dude, whom to me seem to have the best ability to fudge a snap where you wonder....was that a snap (must have been right? he's a TOP flyer!)? I too hate to be in that position.  This has been discussed at length before. 
Also remember that I think some radios have a delay that when you hit the switch it can be programmed to feed certain control surfaces first-I am nuts on this?

I remember that we discussed this before.  According with the rule book the pilot have to show a definitive brake before the snap.  It is very difficult to do this with the snap switch alone unless you are very fast and do the break first and then use the snap switch just after. I agree that the snap done by hand is a lot better and under control.  My personal experience is that if I try to break first the snap is a lot better.  I agree that is very difficult to judge.  

I know that several top pilots got "zeros" at the world championship.  I am guessing that they didn't show a definitive break before the snap. Tony Stillam: Do you know?
