Sorry to dig up a month old thread but I've just installed one of the Fortini with OSD in a new quad and it's doing something super weird. Mid flight it'll suddenly disarm and freeze up. The only way to get it to do anything is to power cycle it. The OSD freezes (doesn't update, though video is still fine), it wont connect to betaflight and it wont re arm or do anything until you power cycle it. Once you do that it'll fly fine, then a minute or 2 later do the same thing. I'm picking this is probably a faulty FC but is there any other possible suggestions? I'm running a holybro 4in1 blheli32 fc.

Hmm, it might be the moron_threshold setting. Don’t be offended, that’s what it’s called. With 32khz gyros it’s pretty common to have to increase the setting higher than defaults.

Haha, yeah I'm familiar with the moron threshold, not something I've had to use before but worth a shot. This is a similar build to what I've run before, the only thing that has changed is the FC, the fact it wont connect to betaflight GUI and basically anything data related freezing made me think it might be a processor issue.

I did see an issue for gyro detection using ButterFlight in the most recent release, but not BF. Still though, increasing moron_threshold is a good idea when running 32Khz gyro's. I suspect things should clear-up for you, but if they don't then report back in here with a log if you can and I can take a closer inspection?

Hard to get a log on this one unfortunately as it's the OSD version which doesn't have native black box support. I have just chucked a video together however of a couple of crashes so you can sorta see what circumstances may contribute. Thinking about it, I'm not sure it'd be the moron threshold because the initial gyro calibration when you first plug in is fine. It's only after it "locks up" like this that you can't do a single thing with it until you disconnect and reconnect the lipo.

Fortini F4-OSD "freezing" problem (0 min 13 sec)

Anyone give me their current scale with a 4in1 that they use and what 4in1 it is?

Update to the freezing problem guiz. I got in touch with furious and the first suggestion was that it was caused by thermal overload being too close to the vtx, I moved the vtx between it and the 4in1 with spacers either side and the problem has gone away and the quad now flies great. Another theory was that there was some kind of interference killing the ICM by having it mounted close to the 4in1. I basically tackled both theories at once and called it a day.

I am looking to buy a cheap flightcontroller to use for this https://oscarliang.com/betaflight-fc-fpv-simulator/
Ideally it should be able to power a reciever from USB. Can the fortini do this?

Yep, I'm setting one of mine up to do this right now.

I want to buy a Fortini OSD but the rev. 2 isn't available in shop I want to buy from. Is the difference to Rev.1 only the additional uart and Softserial or are there other differences or solved issues with the rev.2?
