Mike,

You are right, there are no prolems with the Angel. I too am hoping to get longer flight times since I am moving to 6S from 5S. With the first Angel that I had, I had to push it pretty hard to do some of the pattern maneuvers, and I was flying about 8 minutes on a 5S 5000 pack. It would take around 3900 to 4100 mah to restore the batteries. So I am hoping with a 6S 5000 setup I won't have to push it as hard and get longer flight times. I am flying 10+ minutes on my Wind with 8S 4900 packs and only using about 55 to 60% of the batteries. Really pleased with that setup and plenty of power to perform any maneuver, even with a good wind blowing.

It would be nice to see someone put an IC engine in one. As long as it was not a shaker at idle, the airframe should hold up fine. Keep us informed if you try that route.

Larry...
