Hey 70x7, don't be discouraged. My first build, a Great Planes Spectra flew like a rock and broke it's back on the first try. I built a second one and corrected a few of my mistakes. The first Spectra was way overweight and dragged down by an extra heavy low power NiCd pack. So I watched the weight as I built it and found a much lighter and more powerful LiPo pack. This time it flew, but could have been better,

My next try was a Great Planes PT-60 that I electrified. It flew beautifully, no trim issues, perfect balance and fun to fly.

Yep it may take a few tries but if you enjoy building, like I do, it will be worth it. Just try to learn from your experiences.
