I have a 2 meter WindS Pro which I recently acquired from a good friend. The model is probably 2 years old and has close to 200 flights. The model had a contra rotating propeller power system installed before I acquired it. The nose section had been modified to accommodate zero degree down thrust and zero degree right thrust. I installed a new Hacker Q80 motor on the nose, attaching it to the nose ring. I did not reinforce the rear of the motor to the fuselage. I re-modified it for 2 1/2 degree right thrust and 1 degree down thrust. I reinforced it amply and was confident in the installation.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I made a normal takeoff at about half throttle. As I turned to a right downwind, I powered up to about 3/4 throttle for my usual trim pass. I was in a right bank, and was rolling to the right. I heard a very loud "whack" noise. I continued my turn and only then did I realize that something had changed. I managed to land the model, not realizing that I had lost the motor. It was difficult landing because of the resultant aft CG. The fuselage was missing the first 4 inches. It was also very apparent that torque had sheared the motor off the fuselage. I theorize that the combination of the right roll and the power up caused a gyroscopic effect on the model, shearing the nose off the model.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I wanted to share this to possibly alert others to a nose ring installation of their high power motors. Be aware of the forces that can be produced by these high torque motors. I don't know whether providing a rear brace on the installation would have made a difference. I don't think so. The fuselage was "torn" well behind where the rear brace would have been.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
