Hey Matt, Got to fly yesterday. !st flight balanced to 4" CG as per instructions, it went 20' down the runway nose lifted and flipped over. We moved the CG to 1 5/8 as per theCG calculator, got flight but still very tail heavy, had to make a "U" turn and emergency landing damaging the landing gear. Made repairs to the landing gear moved some weight forward and tried again. The controls between the transmitter and the plane were way to sensitive, I ended up in the most perfect flat spin I have ever seen....I wowed my buddies at the field! I could not get it out of this spin and was lucky that the cotton field provided a good cushion, damaging only the landing gear again. So back to the drawing board and I'll probably have it back at the field wed. or thur. I'll let you know what happens then.
