This video shows the FrSky X8R S-Bus receiver, and Wookong-M flight control components mounted on the F450 central boards.
The extended arms used in this build make this a 550 class machine, however.
Unhappy with the slop in the fold over GPS antenna mount, I modified the knurled knob, so … Read more...
This video takes a look at programming the throttle limits of a Tiger Motor S25A ESC on the bench, before fitting into a build.
These T-Motor ESCs, a relatively new release, come pre-flashed with “Genuine SimonK Fast Code” firmware.
S25A ESCs came from ReadyMadeRC.
After playing around with layouts, it was time to actually start mounting motors and ESCs for real.
Key components:
• Aimdroix extended aluminium arms
• T-Motor MN3110-15 780kV motors
• T-Motor S25A ESCs
• 4mm bullet connectors
MN3110 motor wires come 600mm long, which is a lot of dead … Read more...
The actual F450/550 hybrid quadcopter build starts, and this video takes a first look at fitting a T-Motor MN3110 to Aimdroix extended arms, and how T-Motor carbon fibre propeller mount to the MN series motors.
• F450 central boards
• Aimdroix extended arms
• T-Motor Navigator series motors
• Wookong-M … Read more...
Components for the quadcopter have been rolling in!
A DJI Wookong-M flight control (FC) system along with an FrSky Taranis radio system were chosen to be the main control components.
This Taranis system uses the FLVSS telemetry module to report LiPo cell voltages back on the Taranis’s display.
Wookong-M is … Read more...
Which connector?
Another $64 question.
Battery charger has alligator clip lead ends, whilst LiPo batteries can come with XT60 or 4mm bullet connectors.
It was decided to standardise on using XT60 connectors.
If you haven’t come across XT60 connectors before, then as described on eflightwiki, they are;

Whilst waiting for some items to arrive, including the propellers, the Du-Bro propeller balancer can be assembled.
Regarded as one of the better balancers out there, it goes together in minutes… even quicker, if you’re not taking pictures of the process!
First thing to do is to align and press … Read more...
From multirotorgear.com.au, the T-Motor MN3110-15 780kV motors arrive.
In this no expense spared unboxing video, see exactly what you get.
After months of researching and seeing what was out there, it was decided to “scratch build” a variant of the popular DJI “Flamewheel F450“. In stock form, the F450 is a mid-sized quadcopter, measuring 450mm motor-to-motor across the diagonal.
However… to optimise payload capability vs AUW (All Up … Read more...
I hate that term “drone”!
Bad connotations and attracts unwelcome negativity from an ignorant general public.
But that’s the name of the local group that organise meets on Meetup.
You can use this facility on a desktop, but they have a smart phone app that really comes into it’s … Read more...

The idea of 2.4 GHz “shoot out” was raised with the VK4 microwavers present at the last 5.7 GHz shoot out.
Both myself and VK4EA did a site recce at the Murrenbong Scout Camp last weekend, and are happy to report there is no wifi crud to be heard, nor … Read more...
Looking for a 1296 MHz (23cm) Power Amplifier?
After discounting a W6PQL based kit, a PE1RKI 23cm 150W Power Amplifier was decided upon.
Like the W6PQL design, the PE1RKI (Bert Modderman) amp uses a pair of XRF-286 transistors, but comes fully assembled and tested AND worked out cheaper (Dec 2012) … Read more...
Results for the WIA VHF/UHF Field Day Summer 2014 contest have just been released.
I was amused (it doesn’t take much) to note that the Contest Manager did not quote the number of logs received, as in recent years.
To satisfy my curiosity, the official summary published as PDF on … Read more...
