Transcripts

the meteor 75 Pro is a great little Park

flyer with its ducted fan design it's

really going to be able to sustain

multiple crashes as you'll see in the

footage behind me without braking and

also being able to be in a position

where you can turtle mode and flip back

over when compared against something

that's equal in class for you know the

size and being able to zoom around yes

you will get a little bit better flight

performance without the ducks on

something like this this little

toothpick but it's not going to be

nearly as durable and being able to do

turtle mode and be able to take the hits

of all the poles and everything without

breaking this will way more likely to

break and it's going to be a lot harder

to make sure that Parts you know the the

carbon fiber design for this is

sustainable into the long-term future

whereas when you're always looking at

something in the whoop class here these

types of frames are going to be made

forever and are very uh agile you know

flexible and you're always going to be

able to get these kind of frames they're

cheap to get you can get stacks of them

at a time in different colors and you're

not reliant on just one manufacturer for

the frame Supply into the future now

when compared to its little brother the

meteor 65 and this is the 2001 edition

not the 2002. you can see there's quite

a bit of size difference so this is

really small this is the pro but 2001

version so it only has the 30 millimeter

props versus the meteor 75 Pro with the

45 millimeter props now doing some

comparisons between these two models you

can see I ran the thrust to weight ratio

the disc area to weight and then just

the straight up weight difference

between the two so let's start with

weight you're all up weight for the

meteor 65 is around 30 grams where the

75 is going to be around 46 grams so 16

grams heavier as you can see there but

when you compare that any ratio for the

disc area

compared between the two you're going to

see that the disc area you have a little

bit more disc area divided by the weight

so the ratio between those two you're

gonna have a little bit more with the 75

Pro

um

take that for what it's worth it feels a

lot more grippy uh in the air it's not

as floaty of course as the lighter

weight meteor 65 but it does have a you

know it's faster and it has some decent

amount of grip in the corners for sure

now as you can see on the images I did a

scale just reversing the props and did

some thrust checking on it and you can

see that I am getting a little bit more

thrust to weight on the 65 Pro versus 75

Pro so take that look for what it's

worth you know it's kind of you have a

little bit more disc area but we are

getting more thrust compared to the

weight with the 65. now as you will

probably see in other reviews uh if

you're doing to do Straight indoor

flying racing you probably want

something like the 65 Pro uh it's

lighter weight so it's not going to

bounce in furniture and walls nearly as

hard that lighter weight is going to be

less to get changed in Direction on

their sharp turns if you're doing any

erasing things like that however if you

are going outside with it or you want

something that's a little inside outside

option definitely the 75 Pro is what I

would be looking at to get that

versatility sure you can take the 65 out

as well but just that really light

weight it's just more susceptible to

wind and things of that nature not that

this is not susceptible to wind but

definitely for outside and kind of

jungle gym ripping or playground you

know flying this uh 75 Pro I really feel

hits the ticket even better than

something like a toothpick like this

just because of the durability this

thing will fly and have better flight

performance but it's not going to be

nearly as durable in the crashes as this

is you know I can break these pretty

easily this as you can see in some of

this footage I'm beating the heck out of

it and it is still doing just fine just

flips right over and keeps on going now

the 75 Pro does come with a custom tune

from beta fpv and you can see the

settings right here and it's truly

customized which is nice to see for once

you can see for whoops definitely they

have to ramp up the damping and then

slide down the tracking a little bit but

there is some room for improvement some

things I would change based on the Black

Box logging so that's another great

thing with the 75 Pro it actually comes

with eight Meg of flash which is plenty

for black box it's enough to contain a

full tuning flight and so if you have

any issues with it or just want to peek

out performance a little bit better yeah

that's another tool in the tool chest to

use so I took a look at that and I have

some tips for you so the first thing I

would do is go to your Google Chrome

browser and go to

esc-configurator.com from there you

gotta plug in your quad make sure it

doesn't connect to betaflight you can go

ahead and hit connect on here and then

you'll have to plug in a battery once

the battery's plugged in you can hit

read setup and that will bring you into

the screen I was just at you can see

they have 96 kilohertz pwm loaded here

that's a little high that's not going to

be great for Prof watch performance so

we're going to reflash all those escs to

do that we're going to hit flash all

escs and from there you can see it

selects the ESC

type right here which matches up here at

the top and then go ahead and select the

latest version and then we're going to

change that to 48 kilohertz you can go

24 kilohertz for better prop wash

performance but your battery's life's

going to suffer from that so 48 I think

is a good balance 96 will give you the

most amount of battery life but the

least the amount of performance so if

you're just racing around in prop wash

is a big thing if you're kind of inside

yeah maybe it's fine but uh if you're

outside probably 48 is what I would

recommend so after you have that

selected all you have to do is hit flash

while it's going through that process

make sure to put a fan on the VTX so you

don't burn it out other little tweaks I

would make is come in here to the beacon

probably set that for two minutes

everything else looks pretty good to me

so from there once we just change that

to two minutes there that's so if you uh

lose the quad or whatever it's still

plugged in after two minutes the esc's

will start to beep for you uh help you

find it Well from there you just go

ahead and hit right settings and then

you should be in good set shape so doing

a two a full tuning flight if you're

familiar with black box at all this

looks pretty good for what you see for

raw noise right here that's a little red

swiggly lines and if we run a

spectrograph on that you can see down

here if I look at my roll access how

that's going to look so this is looking

pretty good we can see this nice trough

which is exactly what we want to see we

do have a broad spectrum of noise around

200 Hertz and up all the way up to

around

675 Hertz somewhere in that and that is

the motor band and also this is probably

where the frame is vibrating we do have

that plastic frame which is very durable

and flexible but yeah it will have a

little bit more vibrations in this but

that's not an issue from 200 to whatever

380 we can definitely Crush that down

with some filtering so the first tip I

would do is take the harmonics for the

RPM filter down to just one harmonic you

can see we don't get much over the motor

band for the second harmonic so we don't

need those two extra filters that just

trims off very little bit but

nevertheless I would bump up the number

of notches set this to 300 for the Q

factor and then move the minimum to

around 150. so what we're trying to do

with that is you can see from 150 Hertz

up to 400 Hertz around here we're trying

to really focus two Dynamic notches in

this Zone to help crush this this peaks

of noise down here for the filtering so

it's going to have two Dynamic notches

roaming around and 150 Hertz to 400

Hertz by taking this Q factor here to

300 instead of 500 it's going to make

those notches just a little bit wider

and so instead of being something like

this they'll be like that a little bit

wider and just kind of focus that area

in and then we're gonna that's gonna add

some more latency work so we're going to

trim off some of that just a little bit

by removing even the harmonics down the

RPM filters so that's one bit of advice

right there any differences from here if

we wanted to thin out or make the

filtering heavier or lighter we would

just adjust this gyro filter slider of

course rates or rates put in your

favorite rates whatever you want to do

for rates right here then in looking at

some of the twitch moves just twitching

back and forth you can see I'm kind of

overshooting uh the moves here so that

means it needs even a little bit more

damping than it already has so you can

see that on the roll axis we continue to

overshoot overshoot overshoot and then

we do the same on the pitch access not

as much overshoot so it's more on the

roll than on the pitch but we'd still

have yeah just just ever man pitch axis

is pretty dang close to being where it

needs to be you can see it's not this

you know this cyan line is not nearly

overshooting the green line as much as

it was on the roll so you hear on the

roll you can definitely see it's

overshooting there so we need a little

bit more damping there checking out the

all we're looking pretty good on the yaw

axis so what they have in there is

pretty Snappy on the all access uh it

did have just the ever so slight washout

from a dive but not really bad at all so

I probably would leave the yaw pins at

where they're at but let's go take a

look at the roll axis and see how we can

tweak that out so on the pids the first

thing I would do is they have Dynamic

damping turned down pretty good so I

would just turn it down the rest of the

way just to simplify things you know

teach their own on that but that's what

I would do and now it will help with

getting the D gains as high as possible

for the best prop wash performance so

yeah it's almost all the way down so

just take that down all the rest of the

way and then you can see our D gains

here now it's a little simpler these are

the same thing you can see it's 52 and

59. so what I want to do is Bump this up

so I'm going to go up to uh it was at

1.45 I'm going to take that up to 1.65

so that's going to take this up to 59

and then I want to adjust this back down

so that this is around 59 so you can see

it was 59 before over 60. that's close

enough and that will give us more

damping on the roll access but a little

you know keep the essentially the same

amount of damping on the pitch access

since that was looking pretty good

already so we basically took this from a

54 up to a 59 value so essentially these

are the same between the two you could

probably yeah you could do something

like that I guess

um let's see here just yeah that would

probably be good just a little bit more

damping essentially I'm setting these

two to the same value and that should

that should be pretty good you can see

these are practically the same value

here as well and then this is a whoop so

we definitely want to crank up that feed

forward uh personally I would crank it

the whole way up

um whoops are usually not very fast to

respond you can see just by looking at

the log here again the amount of delay

between the the sticks is my green line

and the quad actually moving this is

probably like 10 milliseconds or 15

milliseconds depends you can see it

widens out but yeah

um cranking up V4 will take care of that

and you can see some of this

overshooting things like that that's

going on here with that uh too much too

much push not enough damping so we're

looking to fix that there well that's it

for this little guy I hope you found

that helpful and useful check it out

with those settings I think you'll

really enjoy the increased flight

performance with it if you did find this

helpful can I remind you I do have a

patreon links down in the video

description for as little as two dollars

a month you can help support the channel

again link down in the description I

also have links down there where you can

pick this little sucker up if you don't

have one already and uh if you do get

one again check out you know first fly

it the way it is stock don't be changing

things right away but yeah check out

those changes to the ESC settings I'm

really just taking it down to 48k

instead of 96k and then some of those

filter tweaks and PID tweaks and I think

you'll really enjoy the increased flight

performance thanks everybody I hope this

helped
