Dingo - Tank
By franjo.zilic on Jun 17, 2018
Very easy and clean build that is part test rig for VTX and ESCs, and part new main flyer.
Some upgrades might be recommended, manly swapping out ESCs for BLHeli_32 and VTX for a full size Unify HV Pro (although this will make the mounting things different).
PDB will not fit flush to the main plate without small dremell modification of the frame. Modification is simple and should not affect frame toughness in any significant way. Simply cut out one small carbon beam that connects two sides on the rear carbon plate mounted on top of the arms.
Frame seams rock solid and there is no wobble of the arms what so ever.
Cammera is connected to 5V BEC on PDB and VTX is connected to VBAT, no noise is visible on FPV feed, and no capacitors are needed.
I'm running BetaFlight 3.4.0 at the point of writing, and 32/16kHz loop times.
EDIT: Changed VTX, still playing around with ESCs. Original ones from Sabotage where good, but looking for something better.
EDIT 2: FInal configuration posted. Had problems with original VTX, now it is running 32/32 kHz loop times and flying great

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

What version of Betaflight are you running 32k/32k on? I get 100% CPU with this FC at 32k/32k on 3.5.1, and it sounds like others do too: see https://github.com/betaflight/betaflight/issues/6886 and https://github.com/betaflight/betaflight/issues/6885 for example.
Also, have you had any issues with noise with this setup? Have Betaflight filters been enough to overcome the noise of the ICM20602 running at 32k?
I am running 3.4.1 overclocked on 240MHz on 32/32.
But now I have added GPS and there was not enough CPU to keep running 32/32.
It might run as well, but I have not tried yet.
And that gyro is very noise sensitive, but there is nothing that produces noise above or below.
Filter settings on 3.4.1 are for "noisy quad setup" from BF wiki.
