oh he's so tiny hi there everyone today
we are going to be taking a look at
probably the cutest little drone that
ever did drone the brand new beta fpv
a65 in this video I'm going to be taking
you through all of the features and
components of this little drone on the
bench we're going to be taking it for a
fly and I'm going to be giving you my
thoughts and recommendations on the
betaflight tune and on the Drone overall
it's a lot to cover one video so let's
not waste any more time let's dive right
into it if at any point during this
video you want to check out the pricing
and availability of this little guy then
all the links you need are down in the
video description and if you control
click on them you can listen to me
finish this review while you check out
all that information if you love all
things tiny whoops make sure you like
And subscribe to the channel because I'm
going to be testing out a whole bunch of
different tiny whoop Motors and props
over the next few weeks to find the
ultimate drivetrain for your next tiny
whoop DIY build you don't want to miss
out hit that like And subscribe button
all right let's start by taking a look
at this little guy on the bench and the
a65 shares the same injection molded
plastic frame and prop guards as the
meteor 65 but it does have a different
canopy the a65 has this smaller lighter
weight canopy it's got a little hole for
the VTX whip antenna and it's got these
four holes here to adjust the camera up
tilt so if you move this screw forward
that'll pull the canopy back and you can
get higher up tilt the a65 has a new
all-in-one flight controller from BET to
fpv this is their air G4 4 in1 and it's
got everything you would expect it's got
a G4 processor it's got um blue J on the
ESC so you can use bidirectional dshot
and it's got a built-in 400 m video
transmitter on the board as far as I can
tell there's no builtin receiver on this
board so you're going to use a separate
receiver and here I've got the elrs
receiver so this is an little serial
elrs receiver with a chip style antenna
and it's just taped on top of the board
there in terms of power connection we've
got the uh beta fpv BT 2.0 connector
here and that obviously supports both BT
2.0 batteries from beta fpv but also
anything with the g&b a30 connector will
also fit because they have the same pin
diameter and the same plug shape so yeah
bt2.0 or gnb a30 on the bottom of the
board we have this little jst plug here
and the S65 comes with this little USB
adapter which is really neat and helps
save a little bit of weight you can just
plug that in whenever you need to
connect via USB to the flight controller
and then you have this little USBC
breakout board and it's super convenient
cuz you can actually have the Drone sat
flat on the bench and the USB cable is
nowhere near the props which means that
you know if you need to test the motors
or whatever um stick a finger on top of
the Drone you can test the motors it's
nice and safe and you're not going to
get anything caught in the uh in the USB
cable so that's nice one of the really
neat features on this board which we're
going to talk about a bit later is that
it has a 16 megabyte blackbox chip on it
so beta fpv in the past have often not
included blackbox on their flight
controllers it's really nice to see that
this air G4 has that
included the motors are
0702 23,000 KV so these are really tiny
Motors and a modest KV but we'll see how
it performs in the flight test but
certainly um these aren't the largest
Motors that you would fit on something
like a 65 mm but also this drone is very
very light so keeping that motor size
down also helps keep the weight down the
camera on the S65 is the beta fpv C3
micro camera and this has 1200 TV lines
43 aspect ratio and it's switchable from
pal to ntsc depending on what you prefer
to use in your goggles speaking of
Weights let's get some for this little
guy so just the drone on its own comes
in at 17.2 G if we add the 260 Mah lava
pack that brings it up to 24.3 or you
can run the slightly larger 300 Mah lava
pack and that brings it up to 25.5 G so
here's the beta flight configuration for
the S65 we're going to start in the
configuration tab and just have a look
and see what beta fpv have done with the
custom config on this drone we're
running betaf flight 4.5 which is great
so we're on the latest version of
betaflight and we are running a G4
processor so we should have 8K and 4K
pit Loop frequency yep accelerometer is
active obviously for angle mode and we
have air mode permanently enabled OSD
enabled that's all fine and normal
arming angle is set to 180° so the Drone
is always going to be able to arm that's
good to see and we've got a custom board
alignment that's obviously for the uh G4
a AO FC that's on this drone if we go
down we've got dshop Beacon
configuration Beacon tone I always like
to set that to three I think it's easier
to hear and then we have all the other
beep set correctly so we will save and
reboot that jumping now into the pit
tuning tab
and so we got a custom pigum which is
nice to see so theyve put some effort in
there um D gains and p&i gains are both
set to
1.15 that doesn't make much sense when
you've also moved the master multiplier
so um what we can do is just increase
the master multiplier by about 15% or so
and that will be effectively exactly the
same set those back to
one state response is on zero so we got
no feed forward I would suggest that we
want a bit of feed forward to reduce the
delay in the pit controller Dynamic
damping off that's fine and Pitch
tracking 1.1 so okay so we need a little
bit more gain on the pitch axis than
roll which makes sense because the
battery is orientated lengthways on this
drone feed forward
settings these all look
sensible and dynamic damping I mean
these set settings are wrong but we're
not using Dynamic damping anyway we
always set advance to zero because we
don't ever want any advance on Dynamic
damping um we have no Dynamic idle set I
would definitely want to set a dynamic
idle for any small drone it does help
with prop wash particularly if you're
flying fast in Acro mode so I'm going to
set that to 50 to begin with and we'll
see how that
goes for these really tiny drones
sometimes you need more Dynamic idle but
should be absolutely fine to begin
with and everything else looks totally
sensible which is really nice to see
okay jumping into the receiver tab
that's obviously all set up for Express
lrs and is correct and
working we don't have any Telemetry
coming back from the from the Drone so
we should probably enable that so that
we can get battery voltage back from the
Drone to the radio we jump into modes
um these are just my custom modes and
Motors we have bidirectional dshot
enabled fantastic and dynamic idle
obviously is now set and 12 poles on our
Motors black
box thank you beta fpv 16 megabytes of
onboard blackbox storage that's just
fantastic that means we can tune the
Drone get it working just perfectly we
don't have to use an open log or
anything like that it's all built
in two for too long beta fpv flight
controllers have not had blackbox and
I'm really glad to see that they do now
so that's really really great and 16 Meg
is a lot as well for a tiny whoop
normally you only get 8 Meg so 16 Meg is
great to see and I think that pretty
much covers all of the bef flight
configuration so I've just got back from
flying the a65 around the flat as you
can probably tell from the goggle marks
on my face and I flew it with the 260
Mah and the 300 Mah beta fpv lava 1s
batteries I got about 4 minutes of
flight time cruising angle mode with the
260 Mah and that went up to 5 minutes of
flight time cruising in angle mode with
the 300
Mah in terms of how the Drone felt to
fly the tune was really good I didn't
notice any strangenesses with um how the
Drone was behaving and it flew really
well both in angle and Acro mode with
the 300 Milah pack the Drone was a
little bit calmer a little bit more
sedate a bit easier to control flying
through tight gaps but when I switched
to the 260 Mah pack I noticed that the
Drone was no noticeably quicker to
respond faster to accelerate faster to
change direction because that battery is
just that much lighter and I also found
actually it was a little bit more
difficult to control the Drone flying
under objects and flying through tight
gaps because it was more responsive and
I think I might benefit from a little
bit of throttle Expo when I'm using that
lighter 260 milliamp power pack so that
I have a bit more low throttle control I
didn't need that at all with the 300
mamp in terms of the camera the camera
picture from the Drone is really nice
the camera copes with changing light
levels reasonably well um it doesn't
stay Overexposed for too long it it
changes its exposure nice and quickly
and I didn't have any trouble flying
from darker areas of the flat into
lighter areas of the flat with uh the
camera kind of compensating for that
change in light level the Drone was set
to 25 M output power on the VTX and that
was absolutely fine I didn't notice any
dropouts or anything I think going up to
200 or even 400 Ms output power is only
really necessary if you're flying longer
distances you want to fly behind walls
or fly outdoors I saw a little bit of
occasional white Flash from Wi-Fi but it
was totally fine totally flyable and the
picture from the camera was lovely now
let's take a look at the configuration
in betaflight the tune on the Drone and
see if there is anything we can do to
improve it even further now I know that
beta fpv have put a custom pit tune on
this drone but their tune isn't perfect
it's a little conservative in some areas
so I wanted to give give you my tune for
the a65 and I'm also going to upload
this as a preset so that you can apply
this directly from Bight configurator in
the presets tab looking first at the
filters the main change that I made here
is just to raise the cut off for gyro
low pass 2 up to 1,000 HZ so we want
just gyro low pass 2 enabled because
we're running a 4K pit Loop so we need
an anti-aliasing filter and gy low pass
2 is that filter so we're going to raise
that to a cut off of ,000 Herz and a pt1
filter type for the RPM filters because
these motors are spinning so so fast you
don't need three notches for this little
drone just a single RPM filter is going
to do everything that you need it to do
so just go ahead and set that to one and
then we are going to need the Dynam
Dynamic Notch filter because there is a
nasty frame resonance at about 200 HZ
that we need to take care of and so we
just need a single Notch here with a 500
Q factor and between 120 and 500 HZ for
the frequencies that all works perfectly
fine once you've got all those set you
don't need to change the dterm low pass
filtering that's fine and the your low
pass filter is also fine to leave
enabled once you've got all that set you
can hit save and then we'll move on to
the pids so the PID profile settings are
in this tab and the main changes that
we're going to make here is we're going
to set damping gains to one and slightly
increase the p&i gains to 1.3 to get a
bit of a faster snappier response
because the Drone was a little bit
undertuned with the p&i gains down at
1.15 stick response gains I've moved up
to one just so we get a little bit of
feed forward to improve the
responsiveness of the Drone Dynamic
damping I left at zero that's fine and
then the pitch tracking I found I needed
to increase that because the Drone is
quite a lot heavier quite a lot more
inertia on the pitch axis than the roll
axis because of the orientation of that
battery so I up that to 1.2 the master
multiplier fine to leave at 1.3 of
course as with all of my presets all of
my Tunes you can always nudge that
Master multiplier up a little bit more
to get a faster snappier response and
just make sure to check blackbox logs
because it's really hard to hear
oscillations on little tiny drones like
this so just check the blackbox logs to
make sure you're not getting any P or D
term oscillation but you can try
increasing that Master multiply if you
want but honestly the Drone flies
brilliantly with 1.3 so I just left it
at that
once you're happy with all of this you
can just hit save and that's the pit
chune applied of course you don't need
to go and make these changes manually
you can always just apply my preset and
you'll find that in the presets tab
it'll be called AOS 65 mm or something
along those lines I've checked out this
tune both for the 260 mAh battery and
the 300 mAh battery and the tune is the
same for both of those packs there's not
enough difference in weight to need to
change the tune and it does fly in my
opinion ever are slightly better than
the stock tune particularly when looking
at logs the delay and the speed with
which the Drone responds to inputs is
definitely improved a little bit with
that slightly higher P term and we're
not getting any overshoot or anything
like that so it's all looking pretty
good I also want to test out the output
power of the VTX on this new air G4
all-in-one flight controller so let's
head over to the bench I'm going to hook
the VTX output up to my true RMS power
meter and we're going to see how it
perform forms in the various different
modes that you can set it to Okay so
we've got everything set up on the bench
the Drone is powered over USB 5 Vols now
I have checked that the VTX results are
exactly the same if you power it from a
battery or over USB USB is just easier
because the battery won't go flat the
VTX output is connected through a 30db
attenuator into my ADL 5902 true RMS
power meter and that's going to give us
a very accurate measure of the conducted
output power from the VTX and it's
independent of frequency so we're
starting off with the Drone set to 25 M
of output power on raceband 1 and what
you can see is that the VTX is
outputting just about 200 Ms of output
power so that's eight times the setting
so we've set it to 25 M it's outputting
200 now let me change to raceband 8 so
you can see what happens to the power
okay this is race band 8 now and you can
see that the power has dropped right
down and now we're at just about
20 28 mow something like that there is a
huge variation in output power with this
VTX between race Band 1 and race band 8
and that is um not unexpected often most
btxs will output their maximum power at
the lower frequency but it is important
to bear in mind that you're nowhere near
25 M of conducted output power on
raceband 1 and you're still above 25 M
of conducted output power on Race band 8
now let's change to the 400 m settings
so this is the maximum output power that
the VTX can deliver okay so this is 400
m on raceband 8 and you can see that 400
m on Race band 8 is giving us just about
270 M of conducted output power now let
me change it back to race Band 1 and you
can see kind of what the maximum
conducted output power of this VTX can
deliver okay so this is set now to race
Band 1 and you can see we are getting
over 600 M of conducted output power on
raceband one so it does make a huge
difference what you have the VTX set to
as to the amount of output power that
you get out of it all right so based on
all this testing what have I got to say
about the new beta fpv S65 well let's
start with all the things that I like
about it I really like the frame the
metor 65 Frame has always been a really
good frame for 65 mm tiny whoops it's
lightweight and nice and durable I like
the motors 0702 they're lightweight
Motors 23,000 KV was plenty of
performance for me but they are also
doing a 27,000 KV version for racing
which will give even more performance um
the props seemed really nice and I had
plenty of responsiveness and performance
out of the motors and the props can't
complain there in terms of the canopy
the new canopy for the air um it has all
the same functionality and features as
the meteor 65 canopy at less weight and
weight is so important for tiny whoops
that I'm really pleased they've gone
with this even lighter weight canopy
that's a definite Improvement in terms
of the new um air G4 flight controller
allinone I really like the feature set
of this little flight controller it's
got a new micro custom OSD chip to save
some space and some weight it's got 16
megabytes of onboard blackbox storage
which is huge for a tiny whoop it's got
a G4 processor which is perfectly good
enough to run 4K with all the bells and
whistles on and the custom config and
tune that they put on the flight
controller for this little a65 was
actually pretty good um we've improved
it a little bit in this video but the
outof boox experience was absolutely
fine the Drone flies really nicely with
either the 260 or the 300 Mah beta fpv
lava 1s batteries and the express lrs
receiver I would have liked to have seen
this included on the light controller
board rather than as a separate
component kind of stuck on um that would
have helped save a little bit of weight
and made the whole drone a little bit
more simple and compact but you know it
is what it is the VTX has plenty of
output power it has a big range of
output power sometimes a little bit
different from what the setting is but
okay it's not calibrated or trimmed or
anything like that but it's it's
performing okay and you're getting heaps
of output power on raceband 1 and
overall the output power is very
acceptable in terms of the camera the C3
beta fpv camera is really nice it's got
a nice image the colors are okay and um
its ability to compensate for changing
light levels is Pretty good overall the
image from the camera is pretty nice
it's pretty respectable given that it's
a nanosiz camera and Tiny cameras do
often struggle to get quite the same
Clarity and definition that you get from
a larger camera but this is really good
for Nano camera I'm I'm totally happy
with it and the little whip antenna for
the VTX nice and lightweight it's really
good so yeah there's there's not really
much to fault about this this drone
who's it going to be right for well it's
going to be right for a first drone for
someone never flown fpv before want to
get into fpv want something small
lightweight cheap not too intimidating
this fits the bill it flies really
nicely you can fly Acro with it as well
as angle um and it's got all of the
features on there that you're going to
want to learn how to use like blackbox
and logging and all of that stuff so you
can get into fpv very easily with this
little drone for not too much money it's
also going to be perfect for someone as
just a fire and forget tiny whoop you're
an experienced pilot you could build
your own or maybe you just buy something
that works really nicely out of the box
this is that drone it works beautifully
out of the box and it's got all of the
features that you're going to expect to
see based on your experience with larger
drones so yeah it's really pretty close
to a slam dunk from B to fpv the only
thing that I can find to say is let's
get the
elrs receiver on the board next time
just to get that weight down even more
and make it even more kind of Monolithic
and integrated but I mean if that's the
only thing that I can find oh and if you
don't fly elrs you can buy plug and play
and put your own receiver on there I
mean that that is a benefit so I can't
knock them for it really lovely little
drone everything you need if you want to
pick this drone Up Is Down in the video
