But there is some strange thing. Some letters are missing in the OSD. The 'F' for example.
You can see it clearly in the pictures. Is there something I can do about that?
Odd. Upload the font again in betaflight. Maybe some oddity in the factory flashing...

Looptime - 8K/8K
DShot600 (can't really tell the difference between 600 and 1200 in flight... )
set anti_gravity_gain = 3.000
------------------------
set p_pitch = 54
set i_pitch = 48
set d_pitch = 30
set p_roll = 46
set i_roll = 54
set d_roll = 26
set p_yaw = 70
set i_yaw = 45
set d_yaw = 20
------------------------
set rc_rate = 92
set rc_rate_yaw = 94
set rc_expo = 4
set rc_yaw_expo = 4
set thr_mid = 50
set thr_expo = 0
set roll_srate = 75
set pitch_srate = 76
set yaw_srate = 75
Thx buddy. I did a test hover on stock PIDs/Rates with 8K/8K and DSHOT1200 and no problems. CPU% on Betaflight also remains very low.

As it happens I'd also setup the Oscar Liang PIDs/Rates over the weekend after stumbling upon them! Haven't had a chance to try them in the field yet. Glad they are working well for you

I used CH16 (AUX 12 in Betaflight) for my RSSI telem on my XSR and it works like a charm. Hope the video posted earlier helps.

Thx again, Steve

Was flying with the Pagoda antenna yesterday...unless it only works with with the RX with a Pagoda, I'm not that impressed. Getting a lot more breakup of signal.

Was it a legit Pagoda from a reputable source or a cheap (not to spec) version?

Was a cheaper one, $15 or so, but from a local dealer...well somewhat local, little over an hour away

The issue with Pagoda antennas is that they have to be made perfectly to function as intended any slight deviation from the recommended specs causes a drop off in performance which is why although pagodas are really great when they get mass-produced you start to see issues like these and not to mention they are easily damaged....

No damage, looked at it, plates look even. Soldering joints look perfect too. Are they sensitive to channels more? Would using one on my goggles help?

It should... I need fact most people use them on only the receiving end due to the durability issues. I'm no expert though...

UXII? That a fake one. I have been using mini AXII antenna a lot, with the uf.l connector. Great antenna. I thought the Pagoda was supposed to be as good or better.

Never looked...but this is a quad you probably won't be putting GPS on...it has a tight fit for everything.
