I finally lost my second .30 109. I had over 100 flights and several gallons of gas. Lately I have been using it to test maneuvers before trying them on my larger war birds. I was just playing around with it today at the field (Markham Park). I was doing touch and goes and stall turns. On about my 5th stall turn the plane went into an unexpected flat spin. I was at about 100 feet and I was able to pull it out of it easily. I was excited because I had never gotten a war bird to flat spin before. I decided to try to get the plane into another flat spin. After a couple of trys I succeeded (kinda). I climbed to a "safe" altitude and went into a perfect flat spin and applied a lot of throttle to get the spin faster and flatter, and I watched it come down. Then I started trying to get it out of the spin. Long story short I did every thing I could think of but no amount of down elevator and opposite rudder make a difference. The plane went in and broke up. I will miss my little 109, but I have already replaced it with the Global AT6 .15 .
