Ran into this issue with Shark Byte RX 5.1 receiver and TX5S.1 with Runcam Nano HD camera.

I got a pixelated image from the camera. LED on the board was solid blue, and solid red. Documentation said if blue LED is not lit then there’s a camera connection problem, but mine was fine. And the Shark Byte receiver was picking up transmission and switching to it, so the transmission itself was not the problem. I discovered that it was just a firmware update necessary; but there won't be any indicator of a firmware mismatch issue otherwise so hopefully if you're pulling your hair out thinking maybe the connector isn't seated right, or the board is defective, fear not, it's probably just simple firmware! I walk through the shark byte firmware update process

ESC - Configurator, a utility designed to simplify updating and configuring of your ESCs.

ESC-Configurator: BlueJay Firmware Troubleshooting & Music 🎵 (Mobula 6 Setup) (16 min 8 sec)

Bluejay is BLHeli_S based firmware capable of bi-directional DShot - so a great choice if you want to run RPM filtering on your rig. This project also aims to clean up and simplify the original BLHeli_S source code. A startup sound editor is also part of the deal.

I flash it to my Mobula 6, some problems and issues occur -- 1 motor stops spinning after the flash of the firmware.

The technical troubleshooting is all left in. Full chapterization.

RPM filtering and dynamic idle RPM settings worked great to tune this out, running 8k/8k and DSHOT 600. The video provides a brief overview of my experience working with the stack.

it's the Mobula 7 V2, and well... this drone is old news now. So why are we taking a look at it 1 year later? As we approach micro season here in North America, the price has come down significantly. I bought my Mobula 7 V2 for around $70 shipped a couple of months ago, and it originally sold for $100+ shipped. In this review we'll figure out if it's worth the price drop. I'll be talking flight, specs, a possible quiet upgrade from the factory, batteries, cheap modifications, and more.

GepRC CinePro 4K HD Drone (Full Review & Flight Video) (18 min 2 sec)

Video Quality

The camera is the most important thing in a cinematic drone; you want to take good video... and the CinePro can do that. It has a Caddx FPV Tariser 4K camera. The dynamic range and color on this is excellent; and there's good reason why. It consists of two sensors and lenses; one is for your FPV, or First Person View. The other is for the high definition video. This compartmentalization of sensors keeps your First Person View experience lag free, while not compromising on HD video. It has multiple resolution options, with the ability to shoot up to 4K @ 30 frames per second.

My personal recommendation when using this camera is to shoot at 1440 @ 60 frames, or 2.7k @ 60 frames and actually skip 4k. The video in the introduction was taken in 1440 @ 60 frames per second in a 4:3 aspect ratio. You get the most of the entire 4:3 sensor this way, which is why I did that.

But of course I didn't upload it as raw 1440, in post production I dynamically stretched it using video editing software. This produces a superview-esque effect which looks a lot more natural. You can then upscale to 4K @ 60 frames per second in 16:9, and upload it to YouTube to squeeze the best quality you can get from the site. It looks GREAT if you can tolerate the extra time to do the post production work and...Continue Reading

Battery Strap & Camera Setup

I tossed the included straps, as they were of low quality and too short. Routed ones I had over the top of the frame that way the entire bottom is free for a rubberized battery grip. Be careful when you setup the battery strap like this, you don't want the strap to be pulling on the esc part of the stack at all which means you'll need to finagle it to run as flat as possible across the bottom.

The 3D printed TPU canopy is great because it's hard to break but as you can see the camera is kind of just held in there not by much. The whole canopy flexes quite a bit which can be jello inducing. One great suggestion by a dude over at RCGroups forums named soloprofan is to put some zip ties on the front of the mount and that should help to keep it from moving around so much and I've done that and can see noticible improvement.

VTX Setup

After you get the battery strap sorted, you're going to want to unlock the FullSpeed FSD TX600 video transmitter for the best video reception. TX600's factory set...Continue Reading
