And my hats off to learning the rubics ... its a lost old school art it seems lol. Something I picked up studying Le Drib's flying ... try varying the speed of your snaps. I dunno if I had to describe it I guess: slam the stick in a direction, but then gradually take it back to center. It requires some discipline because you gotta trust yourself to get back to center before losing momentum. Now get yourself up real high then try it with your rubics cube you'll be amazed how cool it looks. Frankly, I do that with all my snaps though.
Thanks dude! Not going to lie, I've put plenty of hours into Velocidrone; specifically, flying the racing tracks has increased my abilities 10 fold, and I hadn't missed a single day of flying (~12 packs per day,) rain, snow or shine, in the entire month of January. If it weren't for the temperature, I'd be out there rippin it right now. The first version of the rubics cube I learned involved YAW and you will soon read why I don't do it that way anymore. Once I have all of the basic movements burned into my muscle memory, I'm going to start mixing up the speed at which I move my sticks when preforming combos. Doing a 180' flip then slowly rolling out of it is my next goal.
Anyways, to my tuning issues... The meat of my problem with the tune is outlined
here and if you'll notice, on my last post in that thread, I start a tune from scratch using your guide. Disabling filters seemed to help kick the YAW up to setpoint a little bit better, but it's certainly not at all perfect and no matter what I tried, I was still getting altitude gain when YAW spinning a little over half stick. Also, when tuning ROLL and PITCH, I was getting what looks like overshoot (in blackbox) once I'd bring my sticks back to center and a little overshoot at the start of each move. The end-of-move overshoot would happen regardless of how shaky I was at getting my sticks back to center; my sticks were very loose at the time and after tightening them up to get rid of my back-to-center shakiness, the overshoots still occurred. On slower rolls and flips, everything is smooth. Aside from the blackbox logs, the ROLL feels very sharp, although I was having some bounce-back issues with PITCH unless I brought the P/D ratio up to ~1:1. In addition to that, starting feed forward at 150 for ROLL and PITCH made the motors a little too hot; not scalding hot, but hot enough for me to want to back down to ~120.
I'm still pretty lost when it comes to black boxing and I really need to do another round of it using your method because the previous round was done in the freezing cold which was causing me to rush it a little bit. The tune in the video is my original tune, with filters and everything, which looks fine and ROLL and PITCH feel pretty dang sharp (I can feel the slightest bit of bounce back sometimes,) but there's still a good amount of prop wash, the blackbox logs look totally insane, and worst of all, the YAW axis acts like a top of the line mental patient with any inputs a little over half-stick. I'm always risking it when I add YAW to any of my moves due to the altitude gain and I live in an area where, if you crash, you're going to be spending the next hour cleaning out magnetic dirt (seriously why is this a thing!?) from your motors.
I've actually just finished my Caddx+KISS (Steele clone) build last night and it's ready to fly; depending on which quad I like more, I'm going to sell one of them bundled with my Tango2 to a friend once they get their goggles. Regardless of where the Betaflight build goes, I would like to have it operating as optimally as possible, but especially so if I end up selling it to someone who likely isn't going to want to be bothered tuning anything; that was a bit of a turnoff for them, and right now, I am desperate to have a flying partner haha.
Appreciate your contributions and any advice you can give me!
