I have been running my angel 50 now for some time. I have used an A50-12S and Hyperion 4025-10 on 5S 3800. I can report that that the performance is very good. I think the 6S has more power and better duration even though the amp draw is lower.

I have the angel 30 which I run on 4S 2250. I use the same packs on bandit hotliner and demon F5D, I wanted to standardise the packs so I am only using the 4S ones. So I have now changed the motor setup for an 8S setup. I have used TURNIGY 50-65D 270kv and a TURNIGY Sentilon100A HV Xoar 16 x 12 prop, the motor is about 5mm longer than the Hacker

The results: at full power I draw 45A, 1300W, the thust and speed is out of this world, far better than the 5S setups above. As I am using so little average power I am getting an easy 8 to 9 mins flight time. The flight packs in the plane are about 1/3rd of the price of the 5S 3800. Not rite for all, but very good setup for a great plane...

Cheers
