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. A
s I pa
ssed 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><BR><BR><FONT face=sans-serif size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: sans-serif">Plane was new had about 10 flights on it.</SPAN></FONT> <BR><BR><FONT face=sans-serif size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: sans-serif">New battery..NiMH 5 cell pack -no regulator (ran 5 cell packs for years, no regulator) </SPAN></FONT><BR><FONT face=sans-serif size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: sans-serif">Reciever-1999 Stylus PCM-never crashed, wrapped in foam</SPAN></FONT> <BR><FONT face=sans-serif size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: sans-serif">New switch</SPAN></FONT> <BR><FONT fa
