Mini-HowTo PID's and Rates and Expo's Oh My! (Acro Naze32)



So I've done a lot of reading, at first I thought my PID's were tuned nicely with Autotune, well tonight I read



They aren't perfect yet by any means, but they are a LOT better than before. When I hit the throttle hard I don't get nearly the oscillation I had before, and I tuned these to be as agile as I can wrap my little thumbs around. My next task is to play



Yet I was still burning out large lazy rolls and pitch flips. They started crisper, and finished crisper, but the actual roll or flip was big and lazy dropping 20 feet of altitude on average top to bottom. This of course could be mitigated with a burst of throttle at the beginning, but still there is no way I could pull a Charpu Roll through a KeyHole like this.



And then I saw it...







Sitting there, right next to the "Yaw Rate" which I had adjusted weeks ago to improve my yaw authority... "Pitch & Roll Rate"



Well I'll be damned... I bumped that from 0 up to .10 and the results were notable. I bumped it farther to .20 and the results were awesome, I bumped it all the way to .35 and I'm absolutely a pitch flip, roll, ground impacting machine! Before making these changes I had updated my receiver tab and set my RC Rate to 1.25 and my RC Expo to .65, these helped with Acro a lot by themselves and I assume are a good idea.



An example of the "new" room required to flip or roll:

As a side note Charpu flies the style I'm most interested in, so I've been trying to get my skills and craft handling like I see in his video's. With that I found out something I didn't know before, but he shares his config in all his As I've mentioned in the past, I'm new to this game. I'm so new that terms like "Expo" and "Rates" mean very little to me. I've been absorbing data like a sponge and improving my build, my skills and my knowledge every day, yet still little things cause me much trouble along the way. One of those things is that everyone's quad seems to be more agile than mine, doing flips in 1/4 the space mine takes, and doing even double or triple flips long before I hit the ground.So I've done a lot of reading, at first I thought my PID's were tuned nicely with Autotune, well tonight I read this fantastic guide along with this wiki page a dozen times while tweaking my PID's and I definitely made a difference in how the craft handles.They aren't perfect yet by any means, but they are a LOT better than before. When I hit the throttle hard I don't get nearly the oscillation I had before, and I tuned these to be as agile as I can wrap my little thumbs around. My next task is to play with the TPA which sounds like it should get rid of the last of my oscillations.Yet I was still burning out large lazy rolls and pitch flips.
