I have a Draganflyer IV but not a X-Pro. Personally I think X-Pro is way too expensive. $5,000 are you kidding? Draganflyer IV can carry a payload of 4 oz. With 7 times the money, the payload only increases 4 times to 1 lb. Definitely a rip off. If I want to squander that kind of money, I will buy a Steadicoper for $27,000 with 20+ lb payload (that is only $1,350 per lb payload!), GPS controlled, auto-pilot, all metal construction, and a range over 2.5 miles! If I want to go pro, I want a real Pro helicopter.
