You are a proud owner of our new iFlight ProTek25 BNF?
Well guess what, I've made another XING tune.
Last time updated: 2021 July 9th
DISCLAIMER! Please apply my Betaflight diff with care and do a test flight in confined area!
Check your motor temperatures, check the performance and gosh don't fly over water or high trees.
I'm not responsible for your worst case scenario, this is still in testing! But works great for me.
My ProTek25:
- Vista Edition, please consider PIDs won't 100% work for the lighter analog version and probably need to be lowered a bit.
- My Vista installation got an update; I put 4x M2 nylon nuts between AIO FC and only 4x O-rings dampening the Vista and made sure the FC silicon grommets are not squeezed to death.
(The DJI Vista VTX has loads of inertia that has some effect on the FC Gyro obviously; iFlight has therefore also upgraded the installation with the 2nd batch)
My personal settings:
- JESC v2.3 48K and RPM filtering, everything in the Configurator is default!
(You could use Bluejay or JazzMaverick as well, but I'm pretty confident recommending JESC as I personally experienced less issues and the community is pretty much the same)
- Betaflight 4.2.9 (I use the DJI Warning enabled custom *hex)

Some comments on my diff:
- Last test flight was logged! Checkout my BBL below if you want to compare, it's uploaded.
- My motors are cool and stay cool. Make sure yours too!!!
- There's still some little jitters every now and then but cmon... It's a whoop and we won't ever get rid of that (and wind or other outer influences)
- PIDs are relatively high! If you got some overshoots, pull back the PD gain by a notch!
- I've been flying 850mAh 4S on my last tuning flights, 650mAh 4S should just do as fine (which I mostly use for cinematic shots through tiny places)
- I decreased my throttle (scaled limit) to 75%; I don't need that much power and leave some for the PID controller should I hit my throttle stick really hard. Adapt if necessary! (100% stick act as 75% maximum motor rpm in my case, but Betaflight has access to 100% for flight control)
- All Gyro filters are disabled, just the dynamic notch is still active. (RPM filters are enabled of course)
- ALL dynamic D-Term filtering is disabled; D-term static Lowpass filter at 90Hz BIQUAD does the job better in my case.
- My diff is setup for TBS Crossfire (adapt if you fly DJI)
- Pidsum_limit and *_yaw changed to 1000
My Betaflight 4.2.9 diff below:
(There's PIDs, filter settings, OSD settings (incl. DJI Warning) and much more setup, so consider having a look what you want and what you need or just copy/paste all and get a nice surprise)
