<DIV>Hi Keith</DIV>
<DIV> </DIV>
<DIV>Now that's a great idea..... say a two to three second lock-out on neutral
(with throttle cut) then some type of "containing" manoeuvre such as a slow
spin. This would address short term signal loss and give you the safety needed
with a full blown TX failure. You could call it PCM Fail-Safe II for
marketing purposes.... hope the producers are listening err... reading
:-) </DIV>

<DIV><FONT size=2>I have my settings to lock everything in place and drop the
engine to idle. When you hear the engine drop (or notice no pull if there are
other noisy planes close by) a quick wiggle of the wings lets you know if
you're locked out of if your engine is dead. In fact, often it's possible to
know you're locked out before you hear the engine because you can instantly
feel the plane not responding. We don't realize it all the time, but we're
always making tiny adjustments and you can tell immediately when the plane
doesn't respond, even in level flight.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>My thought is that I don't want to *cause* a crash by
throwing the controls into a configuration that could take me from a
controlled attitude to a dangerous attitude if I get just a short signal
interruption. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I think all of the points made are good ones, there's no
perfect answer. I'm just hopeful each time I fly that I don't "loose it". I
think the most important thing is the throttle cut. Beyond that there are
pluses and minuses to both freezing all surfaces and putting it into a spin.
Maybe the ideal solution is a system that would freeze the surfaces for
lockouts of only a second or two, and then the ole' autopilot fly in circles
approach for longer lockouts.</FONT></DIV>

<DIV>Point to ponder: Do you think you'd have noticed that "I ain't

spin? The engine throttle-back could be misconstrued as a
flameout, so I don't think that's too reliable an indicator of
lockout by itself.</DIV>
<DIV>Just curious. I would think it depends what you were doing with
the controls at the time of lockout.</DIV>

<DIV><FONT size=2> My Prophecy went into failsafe
(idle and hold for all other channels) and came out after about a
second ( it seemed like an hour ). I suspect interference but
was not able to find any one month later using the district 6

<DIV>It would be interesting to see statistics on how often a
plane comes out of failsafe and the pilot regains control before
meeting with Mother Earth. It's never happened for me, but
admittedly, I don't use the feature often. Had two sport
airplanes go into lockout when I did use it, and I watched both
spin in.</DIV>
<DIV>I agree a spin recovery isn't the easiest thing to execute
down low when you're in a panic, but I'd venture to say it would
buy you more time than being in a vertical dive while in lockout
would--IF the receiver recovers signal in time. I think it just
comes down to dumb luck really, in what attitude/altitude the
plane is in when the lockout occurs. The question is what are
the odds that your plane would only go into lockout in level
flight vs. the middle of a snap, roll, inverted dive, etc.
Assuming worst case scenario, i.e., no signal recovery, the spin
at least puts the plane back on the field so you can find it,
and hopefully the spin would serve to somewhat lessen the
descent speed at impact. Maybe a flat spin would be better in
that regard.</DIV>
<DIV> </DIV>
<DIV>My luck with such things dictates that it doesn't really
matter what I plan for--the plane's going in, and hard.</DIV>
