I am new to drones and recently tried flips and rolls, and did it successfully with some tutorials help, so just share my experience here. Welcome to discuss and share your ideas here. The accessories links are attached at the end.
OK, let’s go straight to the point – how to set up the CC3D quadcopter for flips and rolls. Follow my steps, you can get it too. I use a semi self-stabilization, here is how to do:
Step 1: Set Mode 2 (Stabilized2)
Click Input, Flight Mode Switch Settings, Bank2 of Stabilized2 in Settings Bank. Then set mode to Rattitude/Rattitude/AxisLock in Stabilized2, and Cruise Control in Thrust (Cruise Control will automatic lower the throttle when drone is upside down), then click Save.
Step 2: Advanced Setting
Click Stabilization, Advanced, Bank2, tick Use Advanced Configuration, then change the value of Rate mode response(deg/s) and Max rate limit (all modes) to 360 in Roll and Pitch (The value is not fixed, you can test and set the most sutiable value yourself, then move to Step 3). Then click Save.
PS:
1. Max rate limit (all modes), same with that in Rate Mode on Basic page, but this one is a global parameter works in any mode, not like Rate Mode only works in Rate, Axislock, Rattitude. The Max rate limit enjoys a top priority: the Max limit value will be taken even if it’s smaller that of Rate mode.
2. Each reconnection to GCS will untick the Use Advanced Configuration box, and return to Basic Page (Use Basic Configuration). Certainly, the corresponding values in Basic and Advanced page are the same, for example, compare Attitude, Rate in Basic with Attitude mode response, Rate mode response in Advanced (the values in basic and advanced seemed to be different are the same actually just because of different unit, i.e. P and I values of Rate Stabilization (Inner loop) in Basic and Advanced), the Advanced page just has more PID values to set.
Step 3: Expert Setting
Click Expert, set Mode Transition in Rattitude to 80 as shown below, (Note: Rattitude is semi self-stabilization, which will turn to manual mode if the lever is pulled over Mode Transition’s value), “80” means if lever on transmitter over 80%, turn to manual mode, if less than 80%, return to the original mode. (For beginners, please set to 90 to avoid misoperation in FPV flight)
MaxAngle: the threshold angle where CruiseControl goes into the inverted mode, InvertdThrustRev for direction control, and InvertedPower for the power to flip. The default value is 105, if you want set the drone for fast flips and rolls, set it 90, which will effectively reduce the descending height.
PS:
1. InvertedThrustRev: if yours is a pitch fixed helicopter (or multicopter), set this to Unreversed.
2. InvertedPower: power output setting in inverted mode. If yours is a multicopter, set it to Zero, so that it will automatic retard throttle in flips.
Click Save and disconnect. Let’s start the flight.
Step 4: Trial Flight
① Select Attitude mode (easy to control), keep the drone in 15m height (or a little higher);
② Toggle to Rattitude mode;
③ Pull the Roll and Pitch levers to the bottom;
④ Keep state of step ③, control the drone to flip 360 degrees, then release Roll or Pitch, or it will fail to do. Besides, use throttle to control the attitude.
