<DIV><FONT face=Arial size=2>I had a similar problem and eventually found the
antenna wire was broken about 3 inches from the receiver. The insulation was
not broken but when I moved the antenna wire, after I removed the receiver
from the airplane, it would stop and start. I also had a bad switch which
checked good with an ohm meter but would not carry any high current load
(like all servos driving at the same time) in another
airplane.</FONT></DIV>

<DIV>I checked all servos but throttle and one aileron servo. All are
working on the bench fine. One of the aileron servos gears is locked
in maximum travel position and I am assuming that was caused in the
crash. However, I could be wrong.</DIV>

<DIV>Fred,</DIV>
<DIV> </DIV>
<DIV>Usually I called pilot (and/or mechanic) error until I find the
cause of the crash. I haven't been in this position in a very long
time. I tend to agree with you since it was clear that I didn't have
control. However, the radio is working even after such a crash.
There was a comment at the field that NiMh batteries can cause this
problem. I will check the battery as much as possible (cycle
increasing the current draws) but not sure if the test will be
valid.</DIV>

<DIV>Thanks,</DIV>

<DIV><FONT size=2>In that case... it may have gone to lock out

<DIV 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></DIV>
<DIV style="MARGIN: 0in 0in 0pt"><O:P></O:P></DIV>
<DIV 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></DIV>
<DIV 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></DIV>
<DIV 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></DIV>
<DIV 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></DIV>
<DIV 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></DIV>
<DIV 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.</DIV>
<DIV 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></DIV>
<DIV 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></DIV>
<DIV 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></DIV>
<DIV 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></DIV>
<DIV style="MARGIN: 0in 0in 0pt"><O:P></O:P></DIV>
<DIV 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></DIV>
<DIV style="MARGIN: 0in 0in 0pt"><O:P></O:P></DIV>
<DIV 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></DIV>
<DIV style="MARGIN: 0in 0in 0pt"><O:P></O:P></DIV>
<DIV style="MARGIN: 0in 0in 0pt">Thanks and have a nice
day,<O:P></O:P></DIV>
