Thanks. I started thinking about what you said. My guess is that those two tail pieces are not fully locked. That would explain a few things. They are pretty tight and I need to remove them and sand them so they can slide more freely. Apprecaiate the advice. I took that Balsa USA Laker out on the lake today. It's 41 degrees and the sun is shining. It slid a few feet and lifted right up. It kept lunging for some reason, I don't know if it was the servo, the radio or the wing was slightly loose. Long story short, the thing would hardly come down by cutting the throttle and then the engine died and it just hung in the breeze, and then the nose began to drop like a rock. Water absorbs crashes, ice really doesn't. Still in one piece but the wing broke at the bolts and the nose needed rebuilt. Looking forward to all pics.
