3.3 GHz FPV Cloverleaf Antenna
I was curious about how much bigger a 3.3 GHz cloverleaf antenna would be, compared to a 5.8 GHz antenna, to see if it was a viable alternative for FPV downlinks on 250 class mini quad.… Read more...

My favorite VTX antenna is the Aomway 4-leaf cloverleaf (sometimes referred to as a skew planar, but “cloverleaf” actually comes from it’s radiation pattern resembling a four leaf cloverleaf!)… Read more...
Apart from measuring regular capacitor and inductor parts, an LC100-A LC meter can be handy tool for measuring the inductance of your mini-quad motor windings, to determine if a particular motor has shorted turns or not.… Read more...

What were the Headplay design engineers thinking???
The Headplay HD 7″ Headset picture looks absolutely stunning when fed with a HDMI source, but the lack of clearance with the connector shroud makes it impossible to use many of the common mini HDMI leads out there.… Read more...
I’m not exactly sure how this happened, it wasn’t a propeller, but one of the ZTW 12A ESCs was nicked by something as it struck a tree.… Read more...

Ripped the SMA antenna connector off your EzUHF receiver in a crash?
It probably looks like this on the solder side:
Components side:
Whilst the SMA jack fitted on this receiver has a narrow body, all is not lost, as you can most likely fit a wide body SMA jack in its place:
When purchasing PCB mount SMA “end launch” style connectors, be aware of the PCB thickness the connector is designed for.… Read more...
Took delivery of a Headplay HD FPV headset, and not along after, took it apart.
As you do!
To help with splitting the two halves, hold the switch panel down with a finger or thumb whilst you separate the halves:
Inside – you can see the slot where the fresnel lens sits, halfway back towards the rear:
If you haven’t taken yours apart yet, something to be aware of when re-assembling:
Watch out for the wires, and make sure you don’t pinch the wires with the screw post on the other shell half.… Read more...
