Review: Spedix F4 Flight Controller – Great for 4in1 ESC
I used to love AIO (all in one) flight controllers, but they can be awkward to use with 4in1 ESC. With 4in1 ESC getting more reliable and easier to work with, I have been looking for a non-AIO FC that works well. This time we are looking at the Spedix F4 FC!
Best Antenna Positioning for 900MHz RC Systems – R9M/Crossfire
Long range radio systems using 900MHz including the Frsky R9M and TBS Crossfire typically use a single dipole antenna on the receiver. The optimal antenna positioning can be different from traditional 2.4GHz systems with diversity monopole antennas on the receivers.
Ummagawd Acrobrat Build with Runcam Split Mini V2
In this post, I will be reviewing and building the Ummagawd Acrobrat 3″ micro frame from Rotor Riot, with the latest Runcam split Mini V2 camera.
F1, F3, F4 and F7 Flight Controller Differences Explained
F1, F3, F4 and F7 are the different processors in flight controllers. This article explains the differences between these MCU, the advantages and disadvantages and help you decide which FC suits you best.
Review: Aomway Commander V2 FPV Goggles
The Aomway Commander V2 FPV goggles is a long-awaited successor to the V1 released back in 2017. Improvements including better optics and a revised OSD menu. These goggles have similar spec and price to the Dominator HD3 and Skyzone SKY03, is it going to be a competitive choice? Let’s find out.
Setup R9M Module and R9 Mini Receiver in Betaflight
This tutorial explains how to setup the R9M TX module and R9 Mini receiver in Betaflight. The R9M is a long range module that operates on 900MHz band. It’s compatible with most Frsky’s radios including the Taranis X9D-Plus, QX7 and Horus X10.
Uninverted SBUS and Smart Port on Frsky Receivers
In this guide I will show you where to get the uninverted SBUS and Smart Port signals on many different Frsky receivers, including the R-XSR, XSR, X4R-SB and XM.
Review: Jumper T12 Radio | Budget Transmitter for FPV!
The Jumper T12 might be one of the best value radios on the market right now. It’s convenient and flexible as it supports multi-protocol and works with receivers from Flysky, Frsky, Spektrum and most toy quads.
TS80 Soldering Iron vs. TS100 for FPV
I have been asked a few times whether the TS-80 soldering iron is better than the TS-100. In this article I will give you an overview of the TS80 and how it compares to the TS100.
Setup Crossfire to Output SBUS
You might wonder, “isn’t Crossfire faster than SBUS? Why would you still want to use it?” Well yes, you should use CRSF over SBUS whenever possible. Crossfire requires both RX and TX pins of a UART while SBUS only needs the RX pin. When you don’t have a spare UART that then your next option would be using SBUS.
When to Replace/Dispose LiPo Battery?
We discussed how to dispose LiPo batteries, but we still haven’t touched on when we should retire them. So in this article I are going to talk about how I determine if a LiPo battery is old enough to be thrown away.
Mini Quad Crashed into the Ocean | Salt Water = Drone Killer
I was flying at this beautiful seaside spot a few days ago, but my quadcopter failsafe’d and fell into the water. This is a good case study and we can talk about what to do after getting the drone out of water.
