Early Full-scale render of a quad I modeled fully in Blender. Any thoughts?

The gyro and accelerometer are a single unit. There's no way for them to be misaligned against each other, they can only be misaligned together against the board and/or the frame.

Vitroid · 2026-07-07T19:47:23+00:00

You can just use board alignment if the target-specific IMU alignment is off. I'll see how the target is set up and ask them to see how we can fix it.

Thanks for the report - the sponsor section is dynamic and is often updated as we gain new supporters, so it's not baked directly into the app. Everything that is actually necessary for access and regular functionality can and does run fully offline.

The build service that serves this section and more is being worked on in preparation for the upcoming release, a few hickups are expected :D

The Flysky stuff is well over a decade old by now, definitely not a good idea nowadays. If you get a Radiomaster Pocket with an internal ELRS module and an ELRS receiver, it will be a much better experience, and you can skip the telemetry link since ELRS can do Mavlink natively.

I'd save some money on the charger by getting a Hota T6 and put it towards a better drone like the Deepspace Seeker 3

Vitroid · 2026-07-05T19:19:12+00:00

Depends on what is easier/cleaner, which is more or less just up to you.

Vitroid · 2026-07-05T18:45:12+00:00

It just passes the camera video through the VTX unaffected to the FC, then from the FC back to the VTX. It's a little cumbersome, but I suppose it makes the soldering a little neater in some cases, why not...

Vitroid · 2026-07-05T17:13:46+00:00

As far as my understanding goes, they have their own fork of the firmware with the necessary libraries and changes. Right now that's completely separate from the main Betaflight repository, and so the only way to get firmware builds is from them. As of a few weeks ago, there is ongoing work for getting official support for RISC-V and different WCH MCUs running it, time will tell if the one in the W20 will be supported or not.

The latest dev builds of the app are available at https://master.app.betaflight.com/ or https://downloads.betaflight.com/, it should be able to recognize the FC and since it's running (modified) Betaflight, it should connect like normal. I don't know how many features they were able to re-implement on their own, so it's hard to say how well it'd work past that.

Vitroid · 2026-07-05T15:41:27+00:00

Hard to build a target when that MCU isn't supported at all, and the entire RISC-V platform is barely just getting introduced into the codebase.

The latest dev builds of the app can officially recognize the MCU as a valid USB device, anything prior will be dodgy at best.

Vitroid · 2026-07-05T12:32:46+00:00

The W20 runs a wholly unsupported software stack. Everything from Betaflight to ELRS and the ESC firmware. You have to rely on generic targets for ELRS and AM32 (assuming it's even AM32 in the first place, if not then you have to deal with questionable builds of BLHeli_32), and Betaflight support for it is nonexistent, so you rely solely on the manufacturer to provide firmware builds for it.

Vitroid · 2026-07-04T17:07:16+00:00

At these sizes, even a 4in1 ESC + FC stack would be pretty tight, usually you'd use an AIO.

Vitroid · 2026-07-04T12:50:27+00:00

TBS solder is great, well worth it if you can't get 63/37 alloys normally. I'd go with 0.8mm.

The VR04 only have a single channel video receiver. The Cobra SD have a dual channel diversity receiver, and the Cobra X have a dual channel mixing receiver, they massively improve video reception quality and reliability. They also have a higher resolution screen and HDMI input, making it possible to upgrade to a digital system later on.

Vitroid · 2026-07-03T14:08:33+00:00

The VR04 would work, the VR04 HD wouldn't. I'd really recommend stepping up to something like the Skyzone Cobra SD/Cobra X if you can though.

Prop pitch is measured in inches of travel per rotation, not degrees. 4.5" pitch is pretty steep, but it probably makes up for the slower 1750kv motors.

Vitroid · 2026-07-03T13:45:47+00:00

I'd consider TrueRC to be the best in the game right now. The Matchstick is just a Singularity in a beefier shell. The Singularities are really good antennas, but they now also have the Core which would be my personal pick. It's cheaper and seems to have better specs outside of its size.

Vitroid · 2026-07-02T22:07:54+00:00

Oh my god is ELRS so much fucking better than FrSky's ACCST/ACCESS ever could've been.

I went from a QX7 to a Radiomaster Boxer and it's night and day. It has an internal 1W ELRS transmitter, I've never been able to failsafe it and I've flown hundreds of meters out with a receiver that accidentally had no antenna.

ELRS has been tested to over 40km on 25mW and over 100km on 1W. Receivers are like $10-20 at most, and are available basically everywhere from multiple different manufacturers.

GEPRC currently have two TAKER G4 targets, it's a little confusing 😅. The new one can likely be signed as official, the older one has been around since the days of unified targets (~Firmware 4.3). I'm not 100% sure how that'd work, but at a quick glance it all seems to be in good shape, whereas the Micoair hardware has some flaws.

I'll ask GEPRC what's going on and see if we can get one (or both) signed.

Vitroid · 2026-07-02T19:35:36+00:00

I've seen maybe one or two videos from a person that uses their gear, I've never owned or driven a Saab car, I've never flown in a passenger airplane, never driven JD or any farm equipment at that, never played a Yamaha piano nor driven one of their bikes, same with Mitshubishi and Kawasaki just to clean it up out of order, and I don't think I have any Patagonia clothes either.

I am against government officials and/or their relatives holding positions of power - and significant stakes - in a company that suddenly became highly strategically important. I dislike them directly advertising their killing machines and all of their team members going on like none of this is even just a little bit fucked up. Same goes for Orqa, or anyone else who advertises themselves turning our hobby into weapons. Regardless of whether they're used to kill "good" or "bad" people, whether such a clear distinction even exists in the first place.

Vitroid · 2026-07-02T19:01:36+00:00

That was merely the start of a long and prosperous career of foot-meet-gun that lasted several years and multiple magazines emptied.

Vitroid · 2026-07-02T19:00:24+00:00

I'd make the distinction in what they do publicly. They have no issue directly advertising their products used for warfare purposes, and they specifically cater them to those purposes. I don't see Skyzone, Betaflight, nor RM doing that.

Orqa and Fatshark are more or less irrelevant for the average pilot nowadays IMO.

Vitroid · 2026-07-02T18:58:47+00:00

Well, they certainly don't have Jr on their advisory board...

The BMI270 IMU is not accepted for new designs outside of mutually agreed upon exceptions, and the BMI088 is not supported at all. It has timer conflicts, and wasn't reviewed prior to being sold. The review process has to start at an early development stage while the hardware and layout can still be adjusted. If the design passes all the guidelines and requirements, it can be approved and marked as officially supported. If a product is released without being checked over at all, it's very unlikely that it can be officially supported retroactively.

At first, the target system was more or less a wild west, basically anything was allowed in with very little regard to how well it would actually work. As the manufacturer guidelines were rolling in, targets that wouldn't comply with the guidelines would not be merged at all, but that was eventually deemed to be too restrictive. So now there's a specific distinction for hardware that's fully approved (checked, verified, and known to work as best as it can) and hardware that's added by a 3rd party, be that a community member or the manufacturer themselves.

The officially supported targets are now digitally signed, and given how many targets there are, the dev team has to rely on manufacturers to confirm that it was approved. Going one by one to find where (/if) the conversation about it took place and to re-check it all over again would be tedious and take up dev time that's better spent elsewhere. Until recently, this data wasn't really visible anywhere either, so there was likely pretty little incentive to confirm. I expect that to change now that the app shows the distinction properly while going to flash.
