<P class=MsoNormal style="MARGIN: 0in 0in 0pt">Yes, yesterday afternoon I
lost my Abbra. I was doing the 45 degree down with snap.
After the snap, I could not control the plane. This is my recollection
of events:<o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt"> <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">1. I over rotated the snap
for a kittle more than 90 degrees. It was clear to me at that
early stage that something was going wrong. I snapped to the
right. <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">2. My friend Charlie was
calling for me. He also noticed and said something to put it back
in position. I told him that the plane was not responding.
<o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">3. First reaction was to give
full left to get it back upright. The ailerons did not respond.
When I realized that, I tried to take it out of the dive by given down
elevator since was pracically in inverted position. It did not
respond. It that aptitude everything goes very fast. Finally, I
tried to give up elevator but was already too late. I am aware that I
applied these control input. <SPAN style="mso-spacerun: yes"> </SPAN>It
was clear to me that there was no reaction. <SPAN
style="mso-spacerun: yes"> </SPAN>I was able to realize that I didn't
have control and I could not avoid the crash. <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">4. I did not have time to do
anything with rudder and throttle. Throttle was at idle.
<o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">5. When we checked the crash
site. One aileron servo was buzzing hard. I disconnected the
servo. Therefore, my first impression that the battery flew off and it
got disconnected with the force of the snap was not valid.<o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">6. I took the plane home as
it came from the crash.<SPAN style="mso-spacerun: yes"> </SPAN>I
disconnected only the ailerons servos. <SPAN
style="mso-spacerun: yes"> </SPAN>I checked the radio and everything is
working fine. Only two servos are not working. The throttle
servo that was practically destroyed in the crash and one aileron servo that
the gears were stripped.<SPAN style="mso-spacerun: yes"> </SPAN>I
believe that this was caused by the force of the impact. <SPAN
style="mso-spacerun: yes"> </SPAN>There was not evidence of flutter in
the ailerons before the crash or structural damage after coming out of the
snap.</P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">7.<SPAN
style="mso-spacerun: yes"> </SPAN>I believe that the plane was well
over stall speed after the snap. <SPAN
style="mso-spacerun: yes"> </SPAN>Therefore, the plane was not in
stalled condition.<SPAN style="mso-spacerun: yes"> </SPAN>However, I
could be wrong.<o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">7. I use JR all around
with digital servos. PCM receiver with fail safe programmed to cut
engine and leave the servos in the last commanded position.
<o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">8. I use 2300 mah NiMh
battery (4 cells AA Sanyo). I checked the battery voltage and was at
5.15 volts after the crash. Discharged the battery and gave 1540 mah
using 250mah rate. I am planning to cycle the battery with higher
loads. <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">9. It was very hot day.
The plane was sitting in the sun and it was second fly of the day around
2:00 PM. Easily was close to 100 oF. <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt"> <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">At this point, I have to
admit that has to be pilot error since I have not been able to find a
definitive cause of the crash. It is clear that the snap initiated
some kind of failure. Other pilots think that the NiMh battery gave up
at high currents during the snap and caused the crash. I have been
flying this type of battery for two years now with no
problems. <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt"> <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">I am informing this to the
group since I would like to have your feedback. <SPAN
style="mso-spacerun: yes"> </SPAN>If someone had a similar problem and
found the cause of the crash, please let me know. I am going back to
my backup plane (the old hydeout). I have a brand new Abbra so
need to put it together. <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt"> <o:p></o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">Thanks and have a nice
day,<o:p></o:p></P>
