Your right, balance is key to a safe return of an airframe. But the zero I have shown is light enough to have ballast (for its size)and be correctly CGed, and still not be a heavy loaded model. And at the same time it seems to be somewhat durable. Not to fragile as I have seen in the past. As you said many radial models require dead weight to CG, but without the correct CG, your entire model, no matter how light will be dead.
I'll let you guys know how this airframe performs, I'm sure it will be forgiving.
