  • How to Build a DIY LC Power Noise Filter for FPV Drones

    Both electrical motor and ESC are source of electrical noise that influences all devices connected to the same battery. This is why, very often, on airplanes or big multirotors FPV circuit is powered from separate battery. On small or medium drones this can be hard to do: additional weight will influence both flight performance and flight time.…

  • Quick review: Turnigy 2730 1500KV brushless motor

    I’ve bought first Turnigy 2730 1500KV brushless motor by accident. I needed something small and cheap for Depron airboat. Then I needed something similar for a Depron airplane. At the end, in 6 months, I owned 3 T2730 1500KV motors. Not all of them survived the experience. One got lost in the middle of a lake…

  • Detecting Betaflight PID tuning issues with Blackbox: excess P gain

    Detecting Betaflight PID tuning issues with Blackbox: excess P gain

    Almost all quadcopter PID tuning tutorials can be summarized into one sentence: “Increase P until you see oscillations, then lower it”. Plus some thoughts about I and very vague advices about D and that is all. When I got into the hobby, I’ve read all of those tutorials. And I did know more about PID…

  • DIY FPV RC Plane with foam board – The RedCruiser Project

    DIY FPV RC Plane with foam board – The RedCruiser Project

    Few months ago I’ve wrote about my first handmade Depron airplane. It was cool design. Super simple, with KFm-2 airfoil, durable and easy to fly. But it had few serious flaws: That’s why, I have build a second foamboard airplane. This time with pusher propeller mounted on a tower behind wing. Wing is almost the…

  • PPM signal support for FS-i6 radio

    FlySky FS-i6 (or branded Turnigy TGY-i6) is a very decent 6 channel entry level RC radio system. But support for PPM (CPPM) standard is somehow not clear. I have no idea why manufacturer keeps PPM support data so well hidden. Anyway, here it is: how can I enable PPM on i6 radio system? PPM signal…

  • PWM, PPM, and Serial RX explained

    When speaking about radio systems for remote controlled models, multirotor, airplanes, gliders, there are some shortcuts that might be unknown for beginners. Those are: PWM, PPM, Serial RX, S.Bus. Today I will explain basic concepts behind them, and when they are used. PWM PWM, as Pulse Width Modulation, is something a standard for controlling different…

  • 5.8GHz FPV channel frequency table

    5.8GHz FPV channel frequency table

    For 5.8GHz FPV systems, there are 5 main bands divided into 8 channels each. That gives 40 channels free to use. So, in theory, 40 pilots should be able to fly FPV at the same time. Unfortunately, this is not true. First of all, there are transmitters, and there are transmitters. Better, properly tuned, will…

  • How to flash MW OSD to Micro MinimOSD

    How to flash MW OSD to Micro MinimOSD

    While playing with newly arrived Micro MinimOSD and attempting to flash it with latest MW OSD software, I’ve discovered that offical tutorial, as well as many other are missing one tiny detail that makes whole process much harder than expected. In theory, MinimOSD just Arduino Pro Mini with additional hardware. So, in theory, you plug in…

  • Let’s build a FPV drone: motors and electronics

    My 250 class quadcopter project is slowly coming to a successful (hopefully) end. Finally had some time to assemble motors and ESC. Since I wanted to have rather standard setup with 5×3 propellers, I had no super high demand on ESC, I’ve decided to use Turnigy Multistar 10A V2 ESC preflashed with BLHeli software available at Hobby King.…
