RE: Hyperion Helios power and expectations
Bill,
I fly the Helios 90 on a Scorpion 4020-16 with 6s 3700mah (Rhino)packs. ~1250 watts on a 7lb. plane. Maybe not enough power for the upper levels of competition but I fly Sportsman and it's more than enough for that (and I fly in Denver). Plenty of vertical. I fly at half-throttle most of the time and I get 7+ minutes per pack.
Beyond that, I love the plane. Everything was straight out of the box and the build was easy. It's very smooth in the air and with the light setup I fly, it was quite affordable.
Let me know if you have more questions.
