LitterBug tnx here's the autotune, more pics and all the nitty gritty detail components listed at RotorBuilds.
I mistakenly listed 598g AUW when uploading the tune -- that's with a 1500mAh 4S battery that I normally fly, while the autotune was actually with a 850mAh 4S and 534g AUW. For some reason it felt like the autotune took at least twice as long as normal -- much longer than the typical minute -- eventually it stopped the wiggle dance and flew pretty locked in after saving the tune.
The video transmitter is crap. Had to dump it a couple of times when video got unflyable. Got it stuck in a tree.. took about an hour to get it down -- so no satisfying flights today.. Pretty impressed with the Foxeer Monster 1200TVL CMOS camera though. Looks awesome at 16:9 in the Headplay facebox that I fly with.
The star of this build, I think, is the HGLRC F4 Flame -- no issues with dRonin whatsoever. Yaw needs to be offset by -90 when installing as intended by the markings.
dRonin OSD works quite well on the OmnibusF4 target FCs that I've put in my builds, including this one.
