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. </span></font><font color=black><span style='color:black;

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. </span></font><font color=black><span style='color:black;

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 DEFANGED_STYLE="mso-spacerun: yes"> </span>It
was clear to me that there was no reaction. <span DEFANGED_STYLE="mso-spacerun:

at idle. </span></font><font color=black><span style='color:black;

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.</span></font><font

I took the plane home as it came from the crash.<span DEFANGED_STYLE="mso-spacerun:

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

by the force of the impact. <span DEFANGED_STYLE="mso-spacerun: yes"> </span>There

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. </span></font><font color=black><span style='color:black;

this point, I have to admit that has to be pilot error since I have not been

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. </span></font><font
