Good day! Can you fly better freestyle or get better cinematic video
simply by moving your transmitter sticks before flight?
Whaaat?A? That's right, the Betaflight dev's have given us some
quick settings we can use based on the type of flying we'll be doing for that
particular flight. Today, in a continuation of our Micro FPV
Tuning Guide series, i'll show you how to set up these three
quick settings for fast freestyle, HD, and Cinematic flights and how you can
switch between all three from one flight to another without
touching your computer! Got your attention? Then make sure to hit

As I mentioned, this is another video in our Micro FPV Tuning Guide series.
If you've missed any of the previous videos make sure to check out the
playlist through the link in the video description below under the heading
Resources and Links Mentioned in this Video. Up to this point
in our series, we've covered how to simply tune your micro FPV drone's PIDs
and filter settings using the Micro FPV Tuning Guide which is also available for
download through a link below. We've done our micro FPV quadcopter
tuning by using these sliders, enabling our rpm filters, and to get the
most out of our tune we've used the basics of our flight data
recorder and Betaflight Blackbox Explorer to fine-tune both our PIDs and
filters. We haven't even mentioned any of these
other settings over here in the Betaflight PID Tuning tab
other than disabling dmin. Today we're going to look at and adjust some of
these settings to fit our particular flight. Before we
go any further I want to introduce you to the concept of using
PID profiles. We've got three we can play with by changing these values however
we'd like, such as if we'd like to use different
cell batteries on the same quad or perhaps
different PID settings for carrying an external camera
which would add weight. For our purposes today we're just going to start out by
having all three PID profiles with the same PID
and filter settings. So we go to PID profile 2 and move our sliders over to
0.9 and 1.3 and we disable dmin.
0.9,
1.3, disable dmin. Wwe click save. Now if I go back to
PID profile 1, you'll see that these numbers
will be the same.
Then we do the same thing for PID profile 3.
0.9, 1.3, disable dmin. Click save. That's the
same as PID profile 1. We also check to make
sure our filter settings for all three PID profiles
are the same. 1, 2
and 3. They are, great! That was simple. Now we're ready to move on.
In Betaflight 4.2 the dev's have set up these quick setting snippets you can
copy and paste into your PID profiles to match the type
of flying you'll be doing. We'll take a closer look at these three
in just a minute but at this point i just want to mention that we will NOT
copy and paste these into our CLI every time we want to change between settings.
We're going to use our transmitter sticks instead. First let's take a quick
look at what these settings are using our Diamondback Rattler frame
build (which by the way you can pre-order the Rattler frame kit now
for the second limited-quantity batch soon to be in stock).
It can be found on the FPV Pilot's Den page at tmacfpv.com and i've linked it
below as well. The parameters we just saw in the
Betaflight 4.2 tuning notes the dev's recommend changing
depending upon your flight style are over here on the left.
If you're like me, before I blindly go about doing anything, I'd like to know
what I'm getting myself into. So, I went ahead and jotted down what each of these
parameters mean and what they do. There are 13 of these
parameters - over half of them have to do with feedforward
and throttle boost. I won't get into the details of
each one, but in general by changing these parameters you're usually making
your quad more responsive ("snappier") or smooth and flowy. Some of these
parameters like RC and feed forward smoothing and the mode
in which feed forward operates, reduce jitter inherit in your control
signals. Let's compare what I currently have on my Rattler 3" Micro FPV
drone build with what the Betaflight dev's recommend
for each of these three types of flying. So the same parameters are over here on
the left and in the second column I have my current Rattler settings. The
numbers in black text on these next three columns
are what the dev's recommend for each type of flight: race or fast freestyle,
HD freestyle, and cinematic. I'm going to go with all of these recommended values
except for the ones I've identified in blue. I'll use those values instead. My
reasoning behind making these changes for the first
three rows I've changed is simply to make the difference between the numbers
in each column the same. For example, the difference between 15 and 10
is 5 and the difference between ten and five is five.
There are equal steps between each. The reason I changed this last value to 100
(which means it's turned off) is because
we saw in the previous slide this is usually for low authority quads
for the yaw axis only - something like a cinewhoop I would guess
and I'm not flying a cinewhoop low authority quad here. So these are the
values including the blue text I'll be using for my PID profiles
1, 2, and 3. Let's go ahead and see how we set those up initially for our
Rattler which will enable us to switch between them out in the field
just by using our transmitter sticks. I've made this stick PID profiles
document for you which has the short and simple instructions
here at the bottom which we'll be doing. You can grab this document for yourself
through a link in the video description below. It says first we go to our CLI tab
in Betaflight and to see all of the original PID
values, type "dump all" and hit return or enter on your keyboard.
So let's go to our CLI tab in Betaflight and perform these steps.
So in our CLI tab in Betaflight, we go to our CLIand type "dump
all" and hit return. The reason i'm doing this is so you
can see the original profile settings (all of them)
in Betaflight before i make any changes. We'll find one of the settings I'm
going to change such as yaw low pass hertz where my
original setting should be 0 and i'm going to change it to 100 for
PID profile 1, 70 for PID profile 2, and 50 for PID profile 3. By the way,
Betaflight doesn't consider these profiles 1,
2, and 3. Betaflight considers these PID profiles 0,
1, and 2. Let's go take a look at what our original setting
actually is for yaw low pass hertz for PID profile 0, according to Betaflight,
and what I'm calling PID profile 1. So we scroll back up and we see that
our PID profiles actually start with profile 0 as i mentioned.
So we're looking for yaw low pass here we go.
Yaw low pass hertz is set to 0. So that's gonna be an indicator for us
when we make our changes for this PID profile 0
(or what I'm calling profile 1). We're gonna change that to 100.
Then we're gonna come back and do a dump all and make sure that it's taking the
change. So let's continue with the next step
which is type "profile 0" without the quotes and
hit return on the keyboard. Then we're gonna copy and paste
these settings for our profile 1 which according to
Betaflight is profile 0. We're going to copy and paste these into
our CLI and hit return on the keyboard. Then
type save and hit return on the keyboard. So let's go to our CLIand type profile
0.
Yyou see here that it took the command. So now we go back to our Stick
PID Profiles document for our race/fast freestyle PID profile 1.
We're just going to copy these, paste them into the CLI,
hit return.
You see it took all of those. Then we type save,
hit return, go back to our CLI and type dump all.
We go to PID profile 0 and take a look at that yaw
low pass hertz setting and see if it actually changed to 100.
Scroll up to profile 0 and we're looking for yaw
low pass hertz. Right here, set to 100. So it did take our changes.
So let's go back to our instructions. It says repeat the same process for the
remaining two pid profiles using the correct profile numbers for each profile.
So that's it, we're done for the first profile!
Then we repeat the same process for the other two, which I'll go ahead and do
now quickly. We type in profile 1.
Then we go to our document and cut and paste our HD freestyle profile
settings. Paste them into the CLI. Hit return.
Type save. Go back to our CLI
Profile 2. Go to our document for our cinematic
flight settings. Copy, paste, hit enter, type
save. So we've repeated the same process
for all of our PID profiles using our correct PID profile numbers
0, 1, and 2 for each of our profiles. Let's now go to our OSD tab in
Betaflight and enable the profile_ pid profile name
or profile_ pid and rate, then click on save.
So we go to our OSD tab and we scroll down
to profile pid profile name or profile pid and rate. This will give you
both your PID profiles and your rate profiles. I've got set up
three different rate profiles on a switch. So, actually the combination
of my PID profiles and my rate profiles will give me 9 different types of
flight profiles I can engage for the particular type of
flying I'm doing. Since today we're only talking about the
PID profiles, i'll go ahead and enable the PID profile
name. You can see that shows up here. I'm going to put it down over here to
the right. So we'll look at this over here in the right hand corner
to see how this changes when we move our sticks.
Click save. Now let's go ahead and see how we change these
PID profiles using our sticks and without touching our computer. All right
to change our PID profile out in the field without touching our computer
there's a couple ways we can do that. Remember, we've got our PID profile name
down here in the lower right hand corner. The first way is the standard way by
entering the OSD menu by moving your left stick
middle left, then pitch forward and you enter your OSD menu.
We're already at profile, so we just move the right stick and we can change our
pid profile from 1
like that. Go ahead and exit out. I'll show you the simpler way
without even entering the osd menu to change your pid profile. Hold the left
stick in the lower left hand corner and if you
move your right stick to the left we're on profile 1. Move it up,
we changed it to profile 2. Move it to the right,
and we're at profile 3. So, if we want to go from our
race/fast freestyle profile 1 to HD freestyle, all we have to do is
that. If we want to fly cinematic,
it's that simple. Let's go give it a shot.
So that's how you can customize your quad settings for a particular type of
flight style just by using your transmitter sticks.
Let me know in the comments below if you're excited about using these
flight style settings. Before you go, make sure to check these out next.
Thanks for your time. I'll see you next video. Clear skies friend!
