If your look in my Gallery, you will see i own and fly the Airsail Piper Tomahawk, i believe i was the first one in the USA to fly one

Anyways the kit was professionally built for me, between 3 guys it took 120hrs to build from the time they got the kit to RTF, it is powered by a Satio .56 the tomahawk weights over 10lbs, it states in the manual 5 to 6lbs, the tomahawk was very tail heavy after it was built.

Anyways i have about 40flights todate without any problems, it flies very scale like with the satio 56 (completely in cowl) , very pleased how it turned out, flies nice, and very scale.
