Proshot is a new ESC protocol that encodes DShot using PWM pulses. In theory there might be some benefits in using Proshot over DShot. However whether or not it makes a noticeable difference and overweight…

I will show you how to flash Frsky receiver firmware on your R-XSR, R9 Mini, XSR, D4R-II, X4R-SB, XM+ and some other RX. Updating RX firmware is useful when you have the wrong firmware that…

Removing header pins on a flight controller or circuit board in general could cause damage to the hardware if it’s not done properly. Here I will show you a couple of examples how I do it safely…

George Chatzisavvidis is very kind to share with us how he enabled OSD menu for the Fatshark Diversity module and goggles button support, by adding a minimOSD.

This is a story of a FC that died right after I finished the build, and there came another FC to the rescue. Thank you Newbeedrone, thank you BeeFlight FC!

Recently I tested the RE1 F4 FC and mPB (PDB) from BrainFPV. When I looked up the FC/PDB combo, I found several ads stating that the RE1 is the most advanced racing flight controller ever made! Wow…

How about some ESC that isn’t BLHeli or KISS? Castle Creations developed the Quadpack ESC’s for multirotors that use their own custom firmware, with some very interesting features.

Polystack is an innovative modular flight controller system by Chickadee Tech. Instead of taking everything on one single FC, Polystack allows you to stack multiple extension boards on top of the FC. Therefore you can…

The Kombini FC is developed by FuriousFPV. It’s a PDB integrated F3 flight controller.

The Piko BLX flight controller is basically a F3 flight controller that is integrated in a PDB, yet it’s tiny and light weight. The FC is developed by FuriousFPV.

Ben Joslin shared his project with us, where he turned his powerful computer/server PSU into a LiPo chargers power supply, which saved him a lot of money.

Many thanks to Aikon for sending me their new SEFM 30A ESC for the tests, which runs the latest ESC firmware – BLHeli_S.
