Yeah that's the truth and it did. But it taught incredible "tuning from scratch" skills. It's always interesting to see the difference between tuning from scratch and making adjustments off of a stock tune. Brushed quads still seem to tune more similar to the days before active braking brushless.
My best results on brushed quads have always been produced by the following long scratch way.
Preflight - get the highest rates you will ever fly with and enter them in. Very important.
First flight: pick roll or pitch axis and lower P to 20, drop I to 10 and D to 5. Have increasing P value assigned to a switch and get in the air - flying with sharp back and fourth action on that axis till the response to the commanded motion feels/sounds really "crisp." It's a learned feeling, but there tends to be a range where you start to feel it - and I push that range to the top ( that's a personal preference thing- stop where you like it). Land and save.
Second flight: Assign D to the switch and fly with the same motion till with the switch activated till it feels/sounds butter smooth. You'll know when you hit it. It comes in just like the warm feeling after a shot of Captain Morgan's. There is not as big of a range on D (it's a matched value to the p you selected), so I stop when I find it. Land and save.
Third flight: Assign I to the switch and fly. Set a bank angle and punch throttle/ drop throttle rapidly. Look for it to hold attitude. Then deactivate switch so it stops increasing I. Now pull a flip. If you are still to low on I, then you will hear the motors pulse at the apex of the flip. Raise it up some if needed. Land and save.
4th, 5th, 6th flights - same thing as 1,2,3 for either roll or pitch.
7th flight - attack yaw. I've never had to lower below stock on anything - so P gets assigned to the switch and I raise looking for that crisp feeling with abrupt movement, and a sharp sound to start and stop the motion. When it gets to high, it will start to bounce up bad on both the start and stop of motion. I stop at a manageable amount of bounce up. Land and save
8th flight - add a hair of D to tame the bounce up. Too much and you will hear the motors dig too long trying to stop the motion.
9th flight - address yaw bounce back if it's there. (Different than the bounce up) If it is there on short sharp stick inputs - add I.
On yaw, if you like sick fast rates, and you take off and yaw spin till its going really really fast - it's gonna bounce back. Don't try to tune that out. Our small motors don't have that much authority.
Flight 10 - fpv process to check I maintaining attitude, and to make sure D has bounce back on flips and any mechanical feeling reigned in.
So 10 flights just to tune for me (the first time - I like to run the gauntlet twice and compare). But when I take the time - it's always way way different then where I end up adjusting from stock... and I like the way it flies significantly more! That's the old school tuning method as I learned it years ago. And if you think it's exhausting to read it - you're right! Hahaha
