When I’ve buoght an oscilloscope (cheap digital DSO201), I’ve decided it would be a good idea to see how different ESC protocols looks like from the signal point of view. Previously I’ve written few words about them, like which is the fastest as so on, but is there something “special” about them? Well, let’s find…

While BLHeli was the best what happened to ESCs since original SimonK firmware, BLHeli has one very serious flaw: BLHeliSuite works only on Windows operating system. Let's be honest here, this sucks. OK, one can use virtual machine and some people succeeded to run it using WINE (I failed) but those are not good solutions.…

There is very little reliable information about Flip32 F4 / Airbot F4 on the internet, so I’ve decided to fix it. Today, pinout map for Flip32 F4 (Betaflight 3.0.1) and some additional notes: Betaflight 3: use REVO target UART1 is only UART with inverters, so S.BUS can be connected only here S.BUS / PPM pin…

Yesterday I’ve received new flight controller for my Reptile X4R 220 quadcopter: Flip32 F4 from ReadyToFlyQuads. This is my first contact with STM32F4 based flight controller and I’m really looking forward to see if it really puts a difference comparing to F3 boards like SPRacingF3 I’ve been using last few months. Some features: STM32F405 CPU…

My Depron FPV airplane is ugly! Good thing is flies quite well…

Recently I’ve got my hands on a pair of cheap APM Power Modules from eBay with integrated 5V BEC and current meter (90A max). Although they are APM designed and will not work stright away with STM32 flight controllers like Naze/CC3D/SPRacingF3 (or rather would work only once since they are 5V scaled and those flight…

ZTW Spider 40A OPTO Small ESC with stock SimonK firmware can be easily flashed with BLHeli using Cleanflight interface. I just did it, the whole process took few minutes. To be true, it took me more time to find out which firmware should those ESC be flashed with, than to flash them. For unknown reason…

LiPo batteries that run RC hobby are potentially dangerous devices. When not handled properly they can ignite or even explode. And they do not live forever. Even the best battery, no matter how taken care off, loses capacity, swells and has to be disposed. When we combine both facts we face a problem: how to…

As long as Naze32 / Flip32 are decent flight controllers for those who does not demand too much, they share very big flaw: low flash memory size. While even a year ago 128kB of flash was enough, times changed, and limited flash makes a problem for advanced flight controller software like INAV. Starting from INAV…
