<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>Yesterday
on my 4th flight of the day my PCM Stylus went nuts. PCM program was set for
idle throttle and about 5-6 clicks(trim wise) of up elevator-all other surfaces
neutral, and this was tested as such by turning off the transmitter. As I
passed by center I noticed that I could not gain altitude and the the throttle
started going from idle to high...then ailerons started oscillating small
left-right deflections. I cut the throttle to the kill position but the engine
persisted up-down bursts. I was able to do a 180 degree turn with aileron
coming back to center...never losing altitude, but unable to change the
altitude,elevator seemed unresponsive. As I passed by center again I was losing
more and more control. The plane flew over the wooded area south of the field
at about 200 feet high, I could not turn and the ailerons rolled the plane
upside down and it went straight down into the trees. This whole episode last
about 45 seconds. Cannot find the plane, and remnants of Gustav are headed my
way.</span></font> <br>

was new had about 10 flights on it.</span></font> <br>

<b><font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif;
font-weight:bold'>What would cause a PCM receiver to do such a thing?</span></font></b><font
size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>
If I had and intermittent signal, once the receiver did get a signal the only
two throttle signals should have been idle (PCM hold) and off (transmitter). I
am going to send the transmitter in just to get checked.</span></font> <br>
