Getting More Comfortable with Rolls

I’m pretty confident in doing rolls now. They’re still a bit sloppy, but I think I need to increase my pitch/aileron swash mix a bit, and I’d like to upgrade the motor. When flying the Trex 450 in the RealFlight simulator, my rolls are all really clean and tight, and I think it’s because the sim uses the 450XL 3550 Kv motor, while my actual helicopter uses the 450L 3150 Kv. I think I also just have more confidence in the sim since if I crash, it doesn’t cost me anything.

Another modification that I’ve made that may tighten up my rolls that I’ve yet to test is in reprogramming my Align RCE BL35G ESC. This ESC came with my 450SA kit, but I never found any instructions on how to program it until recently. It is the newer “G” model, and unlike the older ESC versions, has 5 programming options. I realized that my 5th option which controls the throttle response speed was set to “Low” (1 beep), and have since changed it to “High” (3 beeps).

You can find the manual for the Align RCE-BL25G and RCE-BL35G here:

It’s been really windy here lately so I haven’t taken it up in a while. Here is me doing some rolls from a few weeks ago though (forgive my retarded commentary):
