Begginer quadcopter model for a friend from my old parts.

KK188 has integrated PDB with 5v BEC on the bottom. So first I strated with soldering all the wires to PDB so I can mount it first. This meant desoldering ESC power wires first and soldering them later. Same applied to camera and VTX wires. After that I shortened the wires to needed lenght and soldered them to quad components. Finally I mounted FC and connected all the wires.

Initial start and setup looked OK but I discovered one faulty motor during motor ESC calibration. So the DYS 1306 3100kv were replaced by Racerstar BR1407 3500kv that I ordered for other build.

I have flashed ESC with latest posible BLHeli 14.9.
FC flashed with Betafilght 3.1.7, set Oneshot125, receiver on Uart1 with iBus, Micro MinimOSD on UART3.
During hower test I found out that I switched ESC 1 and 2 which caused wierd yaw /roll flips. When put correctly copter howered just fine.
Realy flight test was not much successfull. Copter flies but it seems to react with some delay. I was playing with Gyro/PID loop times but that does not seem to help. Next I will try to downgrade to Betaflight 3.0.1.

Downgraded to BF3.0.1 with 1kHz/1kHz loops and it flied quite well. Just to be sure I flashed BF3.1.7 back and set 2.66/1.33 kHz loops (that is the most BF let me) and now it flies well also. I also changed props to Diatone 4025. That might helped aswell.

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..
