What are your flight times and headspeeds? Also what are your throttle curves?
I use a DX7se with a Scorpion 1630 motor powered with Outrage 6s 1300 mah. I was down to about 25% my cells capacity right around 5 minutes and 30 seconds (mostly hovering) and wasn't too happy because I thought that I should be getting more minutes. But maybe I'm being greedy.
Here are my throttle curves:
Idle 1: 90%
Idle 2: 95%
Also what is the difference in function between Idle 1 and Idle 2? Is it nothing other than the fact that we can change some applications like throttle curves and expos?
Other than that I just want to say that this heli extremely smooth and autos nicely! It really has got to be one of the best 450s out there.
