I'll try to get some pics on here tomorrow. The idea is an easy one, start with the decoy. We decided oversize were easier to work with. Open it up somehow. For us, we just cut a small V behind the neck, so that we could set the motors in. Got 2 small high power electric motors from radioshack cost about $5 a piece. We set the motors in small wooden frame and wired them to a pack of 3 d batteries. Once through we tack welded, very lightly, a small piece of metal on the end of the shaft on the motor. Worked great on this past weekends youth hunt.
