Snap Switch

[Karl G. Mueller]

Ron,

You're correct on the snap switch timing on the 512 PCM. You could
time the length ( duration ) of the snap without having to release the
snap switch.
Since FAI rules state that you're not allowed to use any timed devices,
this feature was later removed from the transmitter by Futaba.

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.

switch it can be programmed to feed certain control surfaces first-I am nuts
on this?

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.
