[SPAM] RE: *SPAM* [SPAM] Radio Problem / Help

[Larry Diamond]

Lisa has refused to let me use her trainer to test my radio equipment.The
red bow she can do, but her Trainer isn't a test plane.<vbg>

 

Now I got to use a good sport plane.

CLEARLY the problem is the Futaba servos. VBG :-)

 

I know my Airtronics neck strap burns a little whenever I clip it onto a
Futaba transmitter to help someone.

Seriously though.I agree with the person that said NOT to fly this until you
have it resolved it.  I too would look at the Rx again.  I had an Rx a few
years ago (Arch should remember this) that would always lock up in the SAME
maneuver.always a push from inverted.  Turns out the crystal had a hairline
crack in it.  It took more than one "review" of the Rx to find it.  It
behaved normally under normal loads.  it was bizarre.

The last time my Focus flew I had radio problems. (June 2004 @ D4 Shoot-Out,
Muncie)

 

Conditions were windy (25mph+) crosswind from the South if I recall
correctly.

 

As the plane crossed center (right to left) getting ready for the initial
pull in a Non-Rolling Triangle Loop (Intermediate), the plane pitched down
to about a 30 degree dive and dropped the left wing about 45 degrees. This
was a violent event (hence the pucker factor was above 10) and my thumbs had
not yet touched the sticks when this happened.

 

This happened twice. The second time had most everyone watching and all
other  Tx's were turned off. I was the only one out of four people on the
same channel to have a problem.

 

1)       No issues noted with the radio installation and the antenna wire
was in its correct place.

2)       The Tx Module and Rx were sent to the MFG. No problem found.

3)       I did open the Rx battery pack and found a leaking cell. However,
the battery was freshly charged and checked good on the ground after the
flight.

4)       Equipment:

a.       Stylus TX

b.       Airtronics RX - FM / 8 channel

c.       All servos are Futaba Digital except throttle.

d.       YS 1.40L

 

The only problem I found was the Rx battery pack. I have been told by a
number of folks that the battery pack wouldn't be the likely cause of this
problem.

 

Any other thoughts before I try to go fly this plane again?
