Here is my latest mini (70% sized) Blunt Nosed Versa Wing.
I use a small multi-rotor motor, Cobra 2204/28 (kv=2300), an APC 6x4 prop, and a 20A ESC with SimonK. All my builds have FPV gear. Sometimes I'll build one and CG it for larger 4S 2200mAh batteries, most of the time smaller 3S 1300mAh batteries. I adjust the CG of the plane by mounting the motor last. I put everything on, then position the motor to give me the correct CG. With a small 3S battery, I've moved the motor forward and chopped off 2 inches of foam from the back. This is a photo of a 4S build, didn't have to move the motor forward at all.
