Finally got my CineLog30 Analog Corssfire Edition!

Unboxing // CineLog30 Analog CrossFire Version // sub250AUW CineWhoop with Naked GoPro (4 min 46 sec)
(USB-C charging cable not included)

Sadly my GNB 660mAh 4S HV Lipos did not arive yet as well as my Naked Hero8 "Case"... so I am not yet able to "show of" a sub250AUW Naked Hero8 CineWhoop setup... but I designed and printed a "full" GoPro Mount so i could get some initial testing in

First things first... how much does the Analog Crossfire Version weigh without lipo and HD cam...

..not bad

...smallest 4S I have is a 650mAh 4S but it's "high C" and weighs a ton...

There is a new (kind of) kid in the park... and with park I mean the 4K cameras that do that at 60fps which is kind of what I consider the best of both worlds... 60fps just makes footage stay sharp even at speed and 4K just looks super delicious on screens that can support it... and if they don't (4K and/or)60fps) it scales down without any "loss"

SJCAM SJ8 Pro 4K 60fps Action Camera

So let's unbox it
Unboxing // SJ8 Pro // 4K60 // Action Cam // SJCAM (10 min 3 sec)

I like how the black one looks! And it feels solid

one button on top, let's call it the record button and a little lcd in the front...

Update: While this blogpost starts with "only" adding crossfire I am now in the process of getting GPS and iNav working while staying #sub250gAUW so you have to scroll down to see the status quo

Sommer is here and I got some new stuff including a second CrossFire TX (the micro one this time) to play with and when I heard how awesome the new Diatone 3inc PNP R349 is, I had to snag one for myself

Like always I wasn't happy with going the easy rout... I had to add CrossFire and a nice vTx antenna (I did not go for the Unify version for no reason ) and change to #ReversedPropDirection before going for maiden.

Diatone 2019 GT R349 TBS VTX Edition

video antenna:
Realacc UXII Stubby RHCP U.FL

radio control receiver & antenna:
CrossFire Nano Rx SE

Since the day I bought into the CrossFire system I knew I wanted to tip my toes into "longer range"

...I have some 2.4GHz video stuff but it's really old and only puts out 10mW (EU version^^) so not really that "longer range" at all... and the 2.4GHz cloverleaf antennas are huge... (sure not as huge as the 1.3GHz ones ) ...so... long story short... I decided with "my guys"... 5.8GHz is what we will be using for now... at first at 25mW... and later... (sooner than later? ) a bit more

So here is the unboxing of the AKK FX2 Ultimate // 1200mW // 5.8GHz // Video Transmitter
Unboxing // AKK FX2 Ultimate // 1200mW // 5.8GHz // Video Transmitter (4 min 12 sec)

At first, I wanted to put it into my KissCarrierBuild...

It's been some time that I got that exited about some new "hardware"... but it's time to retire the OmniBusF4Pro as my goto iNav Flight Controller... it's not a bad one with it's onboard current sensor and osd... but the lack of "easy" 6 PWM outputs and not enough UARTs to get crazy... (BT+GPS+Mag+AirSpeed+vTx) kind of sad... that's why it's time for this new bad boy!

The new Matek F405-WING Flight Controller promises to give us (I think) everything you could ask for in a Wing FC
(in short, lots of PWM outputs... and lots of UARTs... while still having the current sensor...)

It's time for a new Blogpost... this time it's because I bought into the CrossFire ecosystem and with that got the ability to connect via "Bluetooth" to the FC inflight (the BT connection is actually between my iPhone and the CrossFire Tx and the CrossFire Rx connects to the "BT pads" on the FC)

Two consecutive flights, forgot to let the DVR run on the first one so started recording and did a short second flight.
iPhone // MobileFlight // CrossFire // iNav // Bluetooth relay // Telemetry (7 min 44 sec)

But lets start from the beginning:

I already was hyped when Banggood listed the Nano Talon... but did not jump on it... the single V Tail servo setup just felt wrong (Elevator only^^ but they changed that I think already with the second batch) but with more and more reviews flying in and all of them being super positive, especially with the power setup being "fun on 4S"... I knew I had to get the PNP version...

Hello and welcome to my RaceFlight BigDeal 3inc RaceSpec Millivolt Spark Spektrum BuildBlogPost!

This is going to be a short build blog since there isn't much to build... the BigDeal has a bottom plate, a top plate, and three standoffs... the tpu camera mount slides onto the front standoffs... and the fc mounting screws... well... they are screws and you just put them through the carbon and put the nut on top

You can get all this (- receiver + props) as the RaceSpec from the RaceFlightStore for 225$

so lets get to the heart of the BigDeal, the Millivolt FlightControler To that I connect the SmartAudio cable from the Unify as well as the pins that will join into the connectors on the Spark

Looks like Spektrum (HorizonHobby) is going to push BattGo / XT60i and I really hope this will help it take off... all I want to do is not worry about which lipos I (can) charge at 10A and which at 2A every time and just plug them in and hit start charging

Hello and welcome to my RaceFlight SkinnyKid Revolt Bolt Spektrum Build Blog Post!

Brian Morris aka BrainDrain, famous for taking second place at the "first" Nationals after Chad Nowac back in 2016 and getting into the finals in Dubai and so much more finally released his new racing frame, the SkinnyKid As he is I will be running RaceFlightOne on a Revolt FC and a Bolt ESC as well as the new Warp 8 motors

So let's get started!

DISCLAIMER... I did a few things (I wouldn't call them mistakes... but well ) different in the beginning than they are now, best is to look at all the pics first and I also mention those things during the building process in text from so, please skip through it completely before starting the build to be on the safe side

lets take a quick look at what I am using for this build, most of it is from the RaceFlightStore:

Frame: BrainDrain's SkinnyKid
FC: Revolt V3
ESC: Bolt V2
Motors: 2308 2600 Warp 8
FPV Cam: MicroSwift
vTx: MatekHV
Rx: SPM4649T
OSD: Piggy OSD V2 (not right now but will be put on TX1 then)

I normally don't review what I consider "toy drones", but this one got me interested and I am glad I gave it a shot!

The JJRC H47 ELFIE+ (link to TMART)

It's a light weight drone that has a cam and wifi build in so you can record video and take photos (which look to me like frame gabs of the video) to capture angles you can't reach without a drone.

The case it comes in is actually super nice, everything fits in there and it feels like it will offer some protection as well

Quick overview of whats in the box: manual, screwdriver, 4 spare props, remote and the elfie+

Did not have the intention to do a blog post on this one... but lol... just coming back from the flying field and I crashed the socks out of it and I am both freaking impressed and freaking happy how much fun it was that I just can't hold back and need to do a BP RIGHT NOW!

So it all began when HorizonHobby created a huge hype about a unknow product they were going to do a Apple like Live Keynote on... and it was "just an other plane"... kind of a boomer but well... it was "another VTOL"... but a Tailsitter... hm... nice approach... I actually did not want to buy it... but then a shop I had a discount code had it on preorder and I did order it

Unboxing // X-Vert // VTOL // HorizonHobby (8 min 58 sec)

I am super excited to finally get to play with the Piggy OSDs from Banggood since so far I only had the original HUGE minimOSD to test the RFOSD FW on

This is how I ended up enjoying it

But first lets check how the Piggy looks and how it fits on the "HS1177 style" cam... in this case it's a swift 1 which makes it a bit more difficult to fit since the S1 uses different screws (smaller) and therefore it sin't a perfect match... but doable... you will see

Drops in nicely but you can notice that the screw holes don't line up perfectly

With the lack of inverters on most FCs I spend some time trying to figure out why SBus and other stuff is inverted in the first place... and it seems like it's just done that way to make life harder That's why I am fighting for uSBus (u = uninverted) by bypassing the inverter and saving us from using an inverter on the FC side.

I want to add more and more receivers to this overview, right now all I have working are the XSR and the R620X / R720X but I would gladly add more to this list!

All we need to do is find the "A" pad with the uninverted signal and use that

Let's start with the XSR:

Normally you see me doing quad stuff... but I also like flying fixed wing stuff... but I never ever flew a wing... so when I saw Banggood offering the Reptile S800 for so cheap (and I had seen this or a similar designs quite some time ago and like it) I had to build one!

The package isn't that huge... (sorry... best pic I took... but watch the unboxing below )

...but more parts then expected

...then I had to decide which glue I would pick of those I had laying around

Hello and welcome to my RaceFlight Orca Revolt Spektrum Build Blog Post!

I finally got the Orca frame and couldn't resist building "the RaceFlight quad" (only thing missing is the RF motor, but the new RedBottom S should do fine )

So let's get started! DISCLAIMER... I did a few things (you could call them mistakes) different in the beginning than they are now, best is to look at all the pics first and I also mention those things during the building process in text from ...and I messed up the pics... sorry...

the orca frame, thanks Kalyn for that buying that awesome silver marker :-P

let's add the scews for the stack

So I got my hands on some new high kv motors I am super excited about!

from left to right:
RCX 2205 2633kv (not really new, just as a reference)
GemFan 2205 2700kv
Cobra 2204 2850kv

For the test props I decided on:
T5040 (freyblue yeah xD)
4045BN (work in progress)

The hybrid bullnose tri might be a bit crazy but I always like to push it so why not

ESC is XRotor20A running BLHeli 14.4
FC is a Naze (PIDC disabled)
Tx is a Taranis (0-idle-WOT-idle-0)

the Cobra with it's 26g is definitely the lighter one, it's design is pretty much the same as the 2300kv version and we all know, thats a pretty light motor!

the GemFan with it's "thicker" design has a few grams more to cray around, it weights in at 31g. I guess future will tell if it will take more beating that way, it defiantly looks sturdy

Right from the moment Flyduino announced the KissCarrierBoard (PDB) I fell in love with it... because I hate wires... and I hate heat shrink

...but there was no satisfying frame option back then that would fit the Carrier so I didn't go for it... but a few weeks ago I saw pics of the DroneLegion and instantly new this would be the perfect match!

...so I got in contact with DL, told them that I am interested in their prototype frame (wasn't willing to wait for the release batch) and made them an offer they couldn't say no to

For this build I looked in my spare parts box and picked those components (will change later sorry xD)

FPV Cam: SurveilZone HS1177
vTx: SurveilZone Foxeer 200mW vTx
OSD: Banggood MinimOSD
Receiver: Orange R620X v2 Telemetry DSMX receiver

...later I decided agains the OSD (couldn't get it to work... probably dead max chip) and the receiver and went for "no OSD" and an Orange diversity SpekSat

So I am flying this awesome true X race quad frame for months now so it's about time to blog about my love

TheX it is called It's a mix out of a warpquad style bottom and a krieger style top but the way it mounts the top section plates to the top plate is genius, no ripping those small pads grabbing onto the nut you might have seen with the Krieger or it's clones, but see for yourself


I might not be the "clean build" guy but I just want to fly and keep flying
...and for the Race in Zellhausen I had to add LED lights with switchable colors and since I was running a KissFC by then I had to use the HK intelligent RGB controller
