Good Day everyone and welcome back to TMac FPV-YOUR Home for YOUR Journey to
Better FPV Fun, Flights and Racing Stuff! Today we'll be going over our fourth and
final video transmitter in our Micro FPV Drone Parts Video Transmitter Series-
that being the AKK Oscar's Backpack. The reason it's called a backpack is because
it actually fits on the back of your FPV camera. Not all FPV cameras. This was
designed to fit on the back of the micro Runcams and it also fits on the back of
the Caddx micros as well. The hole pattern for the screws and standoffs
which come with it, and it comes with three screws and standoffs
two of which are only needed-you get a spare as I'm holding here, but the hole
patterns for the backpack fit the Runcam micros and the Caddx micro cameras. It
does not fit the Foxeer cameras at this point in time. You can obviously put the
VTX on the back of your camera but you don't
have to-you can place it anywhere you wish in your Micro FPV Quadcopter build.
If you want the same features as the AKK Oscar's Backpack, there's also the
option of the AKK Race. We'll be going over the dimensions of this as well. For the
Backpack, we'll take a look at its dimensions, its features, we'll test its
output power levels using the ImmersionRC RF Power Meter and then we'll take
it on some test flights at both its Max and Min powers on our video transmitter
test field using the same procedures and flight path as we did for our three
previous video transmitters which we reviewed. We've got an extra BONUS for
you today! After the max and min output power flight tests for the AKK Oscar's
Backpack, we've included a features review of some of the video transmitters
which just didn't quite make our full review series. They lacked in one feature
or another from the feature list which we desire in our Micro FPV Quadcopter
builds. For instance, they may have included the UFL connector instead of an
MMCX connector or they may have included an onboard microphone instead
of an audio input pad or perhaps no audio at all. However, because we realize
that not everyone desires the same features in a video transmitter as we do,
that's the reason we've included those feature reviews on I believe it's 5
other video transmitters at the end of this video. Since there are several parts
to this video we've also included a Hyperlinked Clickable Table of Contents
in the Video Description below. That way, just by clicking on the timestamp you
can jump to whichever section of the video you might be interested in. Also,
for the AKK Oscar's Backpack, the AKK Race, we've included the product links in
the Video Description below for your convenience. Ok, let's get started! Ok the
Backpack is coming in at 18.8 or 19 by 19 - 21 1/2 with the MMCX
connector and about two and a half millimeters thick. . . and it's weighing in
at three grams. AKK Race is coming in at 20 x 25 by about
two millimeters thick. AKK Race 4 grams. All right, here's the
features on both the AKK Backpack and the AKK Race. The Race VTX has the
identical feature set as the AKK Backpack - the main differences being the
size, weight, and the price. They both have 25 and 200 milliwatts output power
settings, they both have MMCX and they both have onboard microphones as opposed
to the audio input pads which our three previous video transmitters which we
reviewed did have. These are our desired features list that we went over in our
three previous video transmitter reviews and the maximum possible range data is
from maxmyrange.com using these parameters. Okay, using the
same procedures as we did for the previous three video transmitters that
we did our review and testing on, we're going to be going over the min and max
powers on Raceband one through eight and also
channel F4. To save time, we're not going to do all of the testing on this video -
we're going to test Raceband 1 and F4 on the video but we're going to show all
of the results for the entire Raceband. So, on Raceband 1 at 5658 megahertz and
our meter set at 5650 with the VTX power setting at 25 milliwatts we're
getting 33.4 milliwatts. And on Raceband 1 at a 200 milliwatt setting we're
getting 416.
And on channel F4 of 5800 megahertz and our meters set at 5800 megahertz,
with a VTX setting of 25 milliwatts we are getting 31.6 milliwatts and on
channel F4 5800 megahertz with a VTX setting of 200 milliwatts we're getting
407 milliwatts. This is the overall summary for the output power levels of
the AKK Backpack VTX at the 25 milliwtt setting and at the 200
milliwatt setting. At the 25 milliwatt setting, the AKK Backpack is
averaging 29.8 milliwatts and at the 200 milliwatts setting the AKK Backpack
is averaging right at 400 milliwatts - and that is not an error, others have
measured this as well. These arrows are just here because channel R5 and F4 - R5 at
5806 and F4 at 5800 megahertz I would expect the output power levels with
frequencies this close together to be somewhat similar and, in fact, they are. At
the 200 milliwatt setting they're only differing by 14 milliwatts and at the 25 milliwatt setting
they're only differing by about 3 1/2 milliwatts.
We'll be using the same video transmitter test field as
we've done for all of our reviews using the same flight path. The reason we do
that is so that if you want to compare two or more video transmitters from
reviews which we've done, you can just open up a separate window in your
browser, stack the windows one on top of the other or side by side if you will
and start playing them simultaneously. Because we're using the same field and
the same flight path in the same conditions you should have a fairly good
comparison of one video transmitter with respect to another. Then, at the end of
this video, what you'll have are 8 different flights using Min and Max
powers on 4 different videos for some outstanding video transmitters
which you could use for your Micro FPV quadcopter build. Before we get to our
test flights, if you found this video useful click on the "Like Button" below,

Welcome to the BONUS ROUND! Here we're gonna go over five of the video
transmitters which just didn't make it to our full review series for one reason
or another. These are 5 VTX's which could actually be outstanding products
for your Micro FPV quad. If any of these are VTX's you'd like to see a full review
on or if you're aware of any other video transmitters which you might be
interested in seeing a full review on, please leave those suggestions in the
Comments Section below and we'll be sure to consider those for future reviews.
What we have here are five different video transmitters from five different
companies but I wanted to point these out because I DO understand that not
everybody has the same concerns or feature "wish list" as I do with regards
to their video transmitter for Micro FPV quadcopter builds. My feature list is
that I want them to be small in size and weight - and by small in size I'm looking
for video transmitters that have dimensions less than or equal to 30
millimeters. I'm looking for video transmitters that are obviously light
in weight. I would like the max output power to be greater than or equal to 200
milliwatts and I do prefer to listen to my motors while flying because I find
that it helps me out with my throttle management and altitude control and just
helps me be a better fpv pilot. In addition to that you're able to capture
the audio in your DVR videos as well. I prefer MMCX connectors because they
last longer and have more mating cycles than the UFL connectors. I find that with
UFL connectors you end up having to either put some solder or silicone or
some other type of substance on them to keep the antennas on consistently. And I
would like smart audio or Tramp protocol so that I can change the power and the
frequencies of the video transmitter without pushing any buttons and watching
LEDs. Now I've tried to highlight in both purple and red those things which I
thought might be interesting to point out to you - purple being potentially good
things and the red or the orange being potentially not-so-good things.
The EWRF e709TM, EWRF is a company that we did the e708TM3 Pro
VTX review on, they've got a another video transmitter - it's smaller in size
and weight than the 708TM3 Pro. It does take 2S - 6S input voltage range.
It's got a max output power of 200 whereas the e708TM3 Pro has a max
output power of 800. It does have an audio in pad so that you can connect
either your camera microphone or an external microphone to it.
The unfortunate thing for me for this particular video transmitter is that it
has the UFL connector. So these are video transmitters that do not meet all of our
feature set desires. In this case, the one that this one does not meet is the UFL
connector. Now is that something that you want to compromise on in order to get
the smaller size and weight? Possibly. For smaller builds these video transmitters
that we've been reviewing and also these that were going over here
are primarily for micro fpv quads in the classes of two two and a half and three
inch. I'm not talking about brushless whoops because I do understand that some
of these VTX's are larger in size and weight than would be desirable for a
brushless whoop. So, depending upon whether you're building a two inch, two
and a half or three inch micro quad will help determine which video transmitter
might be good for your build. If I'm building a 2 inch quad, I might be
willing to sacrifice the connector in order to get a smaller size and weight
with all the rest of these features. And oh, by the way, the cost isn't bad as well.
The next VTX which did not meet our review list is the EXUAV Pro Mini. It
has an IRC Tramp protocol which is similar to smart audio. It's small in
size and weight has 2S - 6s power inputs. It's got the same max output
power and power levels as the EWRF e7092TM. It does have audio input. It's
compromise, if you will, for me is that it does have the UFL
instead of the MMCX - it's got the same features as the EWRF7092-TM however
it comes in at a higher cost. So, between these two if I were to choose between
these two for my build, I would choose the EWRF e7092TM. A slightly larger
and heavier VTX but still within the 30 millimeter or
less dimensions is the AKK FX3 Ultimate. It comes in with smart audio and 2S - 6S
input voltage range. It's got 400 and 600 output power levels.
It doesn't have an audio input pad so you cannot connect an external mic from
your video camera or an electret or MEMs microphone to it because it's got
the built-in mic which generally does not have the same good quality audio
that you would get from an external microphone. It does, however, come in both
an MMCX and UFL versions and the cost is only 18 dollars and 99 cents. So, once
again, here's where you might want to compromise to get the extra power levels
if that's something that you desire. You might want to compromise the audio input
pad for an onboard microphone on the VTX if you're not that interested in getting
fairly good quality audio from your motors while you're flying or in your
DVR videos. I put a solid line here because these all have some sort of
audio feature to them and they're a little bit larger than these two over
here. These two, the RMRC Nano Cricket and the TBS Unify Pro32 Nano, which
has Smart Audio 2.1, are much smaller in size and weight than these other three.
If you're not concerned about audio while you're flying these might be good
options for you for your two-inch builds. The RMRC Nano Cricket has two
power levels, 25 and 200, the Unify Pro 32 has three power levels with a 400
milliwatt max output power - very similar to the TBS Unify Pro Race2 - which we
did a review on. The Nano Cricket does have an MMCX connector and with that it
still comes in at 1.4 grams whereas the Unify Pro32 Nano has a
UFL connector only and it comes in at one gram. Nano Cricket's five dollars
cheaper than the Unify Pro32 Nano so if you're choosing between these two,
or if I were to choose between these two, the trade-offs would be: do I want an
extra 200 milliwatts of max output power over the Nano cricket and sacrifice MMCX
connector and pay an extra five dollars or am I good enough with 200
milliwatts output power and having my preferred MMCX connector? I just wanted
to introduce these to you as potential options for you which do not meet all of
our preferred features for VTX on our Micro FPV builds. Of course, as always for
these video transmitters and all of the video transmitters that we do a full
review on, the links to them will be in the video description below for your
convenience. Thanks for watching, we appreciate your time,
Happy Flying!
