This build is quite a journey, and still ongoing. Here's a video of the current configuration, with a hotshoe mounted FC+OpenLager setup. Everything below is how I got to this:

Last test with G7 before switching to P4K:

I first built this frame before I'd bought the DJI system. Originally it was equipped with iFlight Xing 2814 motors, a Matek H7 Slim FC and a Skystars 65A 4in1 ESC. I'd used a Runcam Eagle and a random AKK half 30x30 style VTX mounted off the rear stack standoffs for an FPV system. The Crossfire Diversity Nano RX was perfect for the RC link as at that time I intended this frame to be the testbed for a head tracking FPV gimbal idea I'd been working on and the RX had plenty of PWM outputs I could directly control the gimbal with. More on that project another time. ;) This configuration only saw a few short test hops in the RDQ parking lot after work before I finally purchased my own set of DJI Goggles and a couple of Air Units. One Air Unit made its way into the DC10, and I gave it a few more timid flights. The SkyStars ESC did fine for gentle flying but what I assumed may have been an overly generous amp rating and my general unfamiliarity with the brand did not inspire confidence enough to "let it rip."

I worked on converting my gimbal quad idea from analog to digital, and from off an off the shelf gimbal to my own custom design. Something with a wide range of balance adjustment because I was having a hard time visualizing where the thing would actually balance. I'll eventually make a build page for that thing, but there's still much to do before it is ready.

Fast forward several months and several builds. When RDQ took delivery of our first batch of 6S 6000mAh LiPo and I held one of these beasts I knew it would be an ideal pack for this project if my DC10 was ever to be anything but a sluggish sky truck.

I'd been keeping an eye on GyroFlow since seeing a reddit post at least a year ago where someone had announced their intention to make their own stabilization software as a learning experience (IIRC) and the idea of being able to stabilize any footage ested me. I love aerial video, but for the most part what we see comes from Mavics and GoPros. I've always

I wanted to fly my Lumix G7 and play with gyroflow, so I upgraded to Brotherhobby Tornado 3115 motors and APD 80F3 individual ESCs and a Radix 2 PB. I designed some TPU ESC mounts with carbon PLA covers to protect my most expensive ESCs ever.

After a few test flights with a Gopro, I designed a 3d printed plate to interface the Shen Drones Universal Camera Mount with my 6S 6000 pack, or directly to with the top plate. I tried strapping the camera mount to the top mounted LiPo, and it was flyable but ridiculously tall.
Alt Tag

I designed a LiPo protector plate so I could bottom mount the battery and not crush it when landing on uneven ground.
Alt Tag

I replaced the simple interface plate for the Shendrones universal camera mount with one that connected to all 6 dampers and bolted to the dc10 top plate.
Alt Tag

The temporary DJI cam standoff mounts were causing some jello, so I designed a heavy duty TPU front and rear for the build. The camera mount is set at 20 degrees, as is the rear GPS mount.
Alt Tag

The Bardpole vertical antenna is mounted to the immortal T antenna so it can be folded down and under the quad when not in use. The rear mount needs a revision to tighten up the locking mechanism of the bardpole. I forgot to model in a place for a horizontal standoff to tie it all together, so it's got a ziptie on right now.
Alt Tag

The air unit antennas were overcrowded by the camera mount, so I used 90 dergree MMCX to SMA extensions attached to the camera mount, and upgraded the antennas to TrueRC 90 dergree SMA Long Singularities. Now the TX antennas have plenty of room to breath, and can be folded down when not in use. Both the air unit and antenna mounts will be revised to purpose built designs...eventually.

I took it out to my spot at the lake for test flights. It's not nearly as loud as I thought it would be! It has a nice smooth low pitch to it. I've been testing different setups using gopro gyro and eventually my own hotshoe mounted fc case design. It started with an matek fc I had collecting dust, but I've currently got a Radix Li in the box with an openlager and a switch. I've got the FC configured to start logging on boot, and the openlager configured to deal with abrupt power loss.

Last BMPCC4K Flights with internal gyro data used in Gyroflow:

Before & After:

Here are some of the first GyroFlow test flights. There's more info in the video descriptions about what changed for each flight.

Here's the first test of hotshoe mounted FC as gyro logger:

This flight was 18 minutes long! I didn't think I could expect this sort of fly time with a big camera on board!
Unfortunately 32mb onboard flash was not enough for an 18 minute flight, so I ended up just warp stabilizing the entire thing to try to reduce the bumps. It took like 6 hours to render, but it came out...okay.

The next test was with the openlager installed. 15 Minutes was no problem for a 32gb sd card and it felt great to see everything working :)

Another test flight, this time just seeing how the G7 / Laowa 75 combo looks at dusk. There were 2 guys at my spot flying mavics! I've flown here for years and never seen another drone, so It was cool to meet some other aerial sightseers. They'd both come out just for sunset.

As of right now I'm waiting for some alphagel dampers and other bits to arrive. I'm learning more about tuning and also working on my Thicc build. Once I've got some hours on this build I'll be putting my pocket 4k onboard and should be making some gorgeous footage down at the lake. I hope to be updating this build several more times as things get more dialed in. If you actually read all this, thanks :)

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
