After tweaking the FC parameters, my CX-20 / Quanum Nova feels like a different quadcopter! It's definitely much more responsive now.
[Instructions]
1. Download APM Planner 2.0. Install it. There will be a couple of prompts including some red warning dialog box for installing "dangerous" unsigned drivers. Allow the installation.
2. Connect the USB cable to the flight controller and to your computer. There should be some activity to complete the driver installation process. If you didn't power up the quadcopter with the 3S cell, there will be continuous beeps.
3. (Firmware upgrade is Optional) Run APM 2.0 and then do not click connect, but go to Initial Setup, Install Firmware. Pick the correct quadcopter firmware (there are two that "looks" like quadcopters). Allow it to install.
4. When done, click Connect. Then Config/Tuning, Full Parameter List. Be careful over there! Remember to write changes when you're done.
