Great first steps in bringing BF angle mode up to snuff! There is TONS of great things in Emuflight that we worked on and tested 1,000's of flights on that would improve it even more, reduce gimbal lock when reaching 90 degrees and smoothing out the whole angle system to give angle pilots tunable control and push the limits. Let's hope more advancements happen, but very happy to see Chris add some Angle Passion back to BF!

I don’t want to sound like I know what I’m talking about but I thought I would post this comment / question. I have not looked at the Betaflight code and my experience with digital filters is primitive at best. But… It seems like you are reinventing digital filters. And it seems like since a drone is physically not attached to anything else, it should be possible to get the precise mechanical response characteristics for the particular drone by inputting sin waves at various frequencies into the system to get the drone’s frequency response curve. Then use that curve to create a matching digital filter which will optimize (at least in theory), the responsiveness of that particular drone. The idea would be to first get the drone to hover. Then wobble it at different frequencies on the three axes to get the response curve for each axes. Then compute the optimum digital filter for the drone for each axes.

I'm visiting Bangkok and flew a 80mm quad with a Vista off a rooftop restaurant. I used angle mode because I wasn't too familiar with the fairly small area and it made my landing more controllable (no inadvertent drifting over the rooftop ledge..) Technically my wife was spotting but not reliably after a few glasses of wine 😄 So there are some benefits to angle mode but you have to fly it completely different to get proper cinematic footage.

Reminds me of the old rate gyros vs heading hold. I believe the issue then was the wind up of the loop that happened the longer you held the stick. Feed forward sounds like some extra gain on the stick authority that happens depending on the rate of initial stick change and again rate that it slows.

Tested on a DIY 2" whoop, flying inside. STM32F411 on a Happymodel ELRS X1 AIO 2-4S (CRAZYBEEF4SX1280). Caddx Vista, so a bit heavy at 78 g without battery & the motors are too small; 1202 8420KV's. The only initial problem was the same as noted on comments in Github: ELRS was lost at first. In CLI, "get express" - the AU domain after flashing is probably wrong and needs to be set again. Diff did not fix this, had to be manually changed. Tested with the defaults (angle_feedforward = 50 and angle_earth_ref = 100). *Very nice behavior.* Finally this whoop runs OK in Angle mode. Was able to hit smaller gaps and fly much faster than with the regular 4.4.4 RC3 it had before this. Rapid turns in tight spaces feel much better. Will test with different values later. I really hope this gets into 4.4.0?

Thanks to you Chris, this feature is already incorporated in Betaflight 4.5. However, I have a query. When I tested the angle mode in Betaflight 4.5, it performed amazingly well, especially with the ease of turns with only yaw inputs given. How can I achieve the same "integrated roll" behavior in the acro mode? I couldn't find any setting options for this. When I attempted a brief flight in acro trainer mode and tried a turn using only yaw inputs, the craft seemed to lose its orientation. It converted the forward pitch into roll, which is indeed the core issue you described in the beginning of this video.

Hey Chris, I stumbled across this video for angle mode, searching for something different, and it's incredible insight into this mode! Great work! I learned a lot here, except I'm currently struggling with one aspect of the angle mode for cinewhoop filming. Everything is flying really slow and smooth in angle mode with the added ff feature but I have tried many setting changes to keep my throttle from bobbing up and down including the reference from your video pertaining to the throttle curve and expo. No matter what I do, I still have a slight movement up and down and can't seem to relax the throttle. It really comes through on the naked go pro footage as the horizon of an indoor atmosphere is moving up and down even after stabilization. Are there any extra tips you have that I can mess around with to get the perfect flight feel. Thanks in advance and for all you do for our hobby!

Too bad it wasnt possible to just copy how like Hover and Auto-level works on Ardupilot, in Normal/Fim mode and Sport Mode, then have the Acro mode from Betaflight. But I'm assuming that its not that simple, but you know what i mean lol. Ardupilot is super stable and is almost like a DJI drone with gps and all the sensors. But deff doesn't haven't that BF Acro mode, but it does have a good manual mode on it if youre able to fly it like that, but it's really not that type of quad anyway.. Awesome work man, it's greatly appreciated!! I'm trying to learn Acro mode on my first true fpv quad, but im starting with angle mode and I'm having trouble with that lol and i know how to fly drones i dont get it, gotta keep practicing my hovering and maneuvering in Acro Trainer mode when i can. But for just normal flight, Angle mode is just killing my drone lol. Plus i tend to start doing a loop of trying to land, but going higher and higher each time, bc its so sensitive and i was applying too much throttle apparently, you're instinct is to give it some throttle, when the drone is coming back down, so it doesn't just crash down. But it goes up slightly or levels out near the ground so you can gently lower, but even little increments or so i thought were giving it too much throttle lol.. Plus i wish the RTH worked properly. Plus with the GPS data you could add Air Brakes, Hover, etc so you're able to start flying even harder drones on say a film or beginner mode. Like you can do on Ardupilot or similar..

Isn't what betaflight put in pretty much identical to the Emuflight angle code that's been around for over a year? A lot of things sound the same to me. In my opinion, angle mode is a very useful mode and is now very underestimated by new pilots. I know one reason is that people would rather commit to one flight mode for all quads. I can understand that, but especially with a micro whoop which flies significantly different to larger copters, I think you can also fly with different flight modes. Especially in whoop racing, angle racing makes progress very quickly. Of course, the skill cap of acro is higher, however it requires a lot of time and practice on the small whoops on tide tracks. Racing at a high level in angle is still hard enough and not easy. So try it! I also use angle on my cinewhoops in many situations.

Keeping yaw rotation around the earth’s vertical/z-axis (rather than the quad’s) is something that silverware has been doing for years. Imo that was the huge draw of NFE Silverware’s angle mode for brushed builds back in the day, and remains one of the main draws of modern day quicksilver. Here’s hoping BF crash recovery and the gyro wind-up issue (not sure that’s the right term, but the thing where it doesn’t fly straight for a few seconds after hard crashes) are improved as well. Quicksilver still handles clipped gates/obstacles better than BF in whoops, imo.
