Well guy's i finally found her. Did'nt get to use vid/plane due to aircraft problems. i just keptup looking in the area i thought it ought to be and lo and behold i FINALLY caught a glimpse of her. It was in a tree upside down almost totally unscathed. I retrieved the plane , but have'nt yet found motor. The firewall definately let go with a baseball size hole in the center.My prop was ballanced and she ran smoothly. I also had dowel rods reinforceing the 4 corners of firewall. i can only guess but she had too many holes drilled in firewall from previous owner as it appears to have broken away in line with those holes (kind of like connect the dots) Anyways i hope everyone benifits from my experiance.I plan to go back with a gps and metal detector so if i don't find motor i can at least mark crash site on gps so when foilage dies down some i could try again.
