<DIV><FONT face=Arial size=2>The loose covering Don describes below, reminds me
of a WW 2 P-51 problem. At high speed, several aircraft had wings peel
off. Not a good thing. Finally, it was tracked down to the fact that
the 50 Cal. ammunition doors were swelling outward, and the increased camber
increased the lift enough (suddenly) that the wings would separate.
Strengthened the doors--end of problem.</FONT></DIV>

glitch - trouble-shooting.</DIV>
<DIV><BR></DIV>Jon, Colin,<BR><BR>I'll pass on something that may or may not
be related. The NMP Li Ion battery packs come with a "JR" type
connector but it's a slightly different design for the pins. There is
play especially if you use it inside a Futaba female connector. That is
what my dad used on his Smart Light Switch design. <BR><BR>So any case,
here's the story. I was flying and something did not feel right.
It felt like it went in to momentary hold, like during the bottom of loop
with 4 point roll (when the servos are loaded quite high). I bring it
down immediately and check the data logger which records zero holds
logged. However, I notice something out of ordinary. The data
logger shows no packet losses, no fades, zero holds. That seems odd
since it always has some minor packet losses during a flight log.
Everything seems normal. I take the switch out and notice that when
I wiggle all the wires its ok, but when I get to the connector from the
battery to the switch I see the smart light flash briefly (showing it goes
under 5.4 volts). Now with no servos on this is odd. So what I
find, after wiggling the connector (almost impossible to reproduce but I do it
finally) inside the yellow clip-on connector-holder thing (the thing where the
connectors clip inside and will not separate even when pulled hard) the light
goes out and stays out. The yellow clip thing allows for some wiggle of
the pins ba ck and forth while the connectors are inside the clip.
I find that its at best its at a high resistence, and at worst it has
intermittant connections. That explains why the rx voltage was
dropping during the loop with 4 point roll. I subsituted a very small
tightly tied tie-wrap in place of the yellow removable clip and the problem
was solved. So I thought I would pass this on. I have heard of at least
one plane lost from the black slip-on clips pulling loose (the one
where you slide one wire on one slot and the other wire in the other slot to
keep the connector from loosening). However , I have never heard or
experienced problems with the yellow clips.<BR><BR>On the topic of trimming,
here is another one of interest. I'm flying tonight, the plane is
trimmed perfectly, then half way through the flight the trim below
quarter throttle goes way out, like the wing is about to separate. Real
bad. Lots of up elevator and opposite aileron required to land.
Just get it on the ground. Felt like it lost an aileron,
elevator side, or both. I land, and after checking everything
carefully I notice a small section of trim covering on the top of the wing-
maybe 6 inches in length is loose. It did not tear off but in the
frontal exposure to wind would lift up like a miniature parachute. After
carefully taping that down I fly again. Same exact thing happens.
This Magic VF3 PHX really isn't happening. I land and guess what,
another, smaller section comes loose (just a little bit at the front edge of
the trim covering), but closer to the tip. I tape that down (boy I wish
I had an Iron with me.). Any case, I fly again and third time is the
charm Everything flies well. If such a small piece of covering
could effect the trim that much, it makes me wonder how much any drag
differential would cause the common pattern pilot headaches in trimming.
Note this- a small amount of drag differential on one wing tip has the same
effect as an out-of rudder trim, except it's non-linear with speed
(drag). Reminds me of the story that George Asteris had of a landing
gear retract that was dragging (hanging down on one side). Upright it
would hang down slightly causing drag, inverted it would go back into the
wheel well and the drag would go away.<BR><BR>One final bit of wisdom.
Plane rolls faster left than right. I go to ATV to adjust control
throws. It does not make sense. I have to add a bunch of ATV in to
get it close. I double check flight trim, guess what, that is
it. I do the clevis thing, get the trim beeps into the center
transmitter trim, and fly. Its perfect, and no ATV required at
all. Plane rolls so much better now. I'm now a 1 or two beep kind
of guy. <BR><BR>Lots of food for thought. Well, I'm off to iron
that covering back down... tight.<BR><BR><BR>Don<BR><BR><BR>-----Ori ginal

They can start oscillating with the engine running, and really kick up
the amps. Put a servo tester on them with a slow sweep and see

travel. I've had a single aileron servo draw 1.5 amps by itself

Nothing high tech is needed. One by one, move your controls and
carefully watch to see if it looks l<BR>ike the any of them are
straining at the end of their maximum travel. Check the throttle
in particular. I have seen digital servo cases melt from having
the throw set up further than the linkage will allow. If that's
not it, disconnect the linkages at servo and work the control surface
by hand. If it does not move very freely, fix it. If you
don't find the problem there, work the servos around in a 10 minute
mock flight on the ground, except exaggerate the movements
considerably since there will be no air load and engine vibration to
add to the loa d. Listen to each servo. If it sounds like
it's having a problem, remove it and check it out on the bench.
If there's nothing obviously wrong by the sound of things, then feel
the servo cases to see<BR> if any of them are getting
warm, or even try smelling them for that characteristic smell that hot
electronics tend to have. If there is a regulator that got so
hot as to discolor it, and there is nothing at all wrong with the
linkages or control surfaces, then this ought to find the
culprit.<BR><BR>Ed<BR>----- Original Message ----- From: "David Cotton

believe a bad battery could cause the engine to rev up unless your
battery failsafe isn't set properly. Make sure it is.<BR><BR><BR>The
first thing I would look at is the possibility that the throttle servo
is stalled at low speed. That could be pulling the battery/voltage
regulator voltage down and it could recover after you started to
throttle up and removed the heavy load.<BR><BR><BR>Finally I would run
a one amp discharge test on the battery after it is fully charged to
see if the battery is near its original capacity. The best way
to<BR> do this is to plot the voltage vs. time taking readings
every 5 to 10 minutes.<BR><BR><BR>Hope this helps. Let us know what
you find.<BR><BR><BR>Jim<BR><BR><BR><BR><BR><BR>On Apr 25, 2009, at
