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.

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
