Parametric Propellers

Le Tue 09 April 2019

This is an article about using a pair of OpenSCAD scripts to generate multi-bladed propellers or folding propellers for 3D printing.

Organising a Public Drone Racing Event

Le Tue 13 June 2017

Each year Hutt City Council runs a STEMM festival to promote the “Technology Valley” concept. As part of the STEMM festival for 2017, the Council and Hutt City Libraries were keen to run a Drone Racing Day with the local talent turning up to one of the local sports-grounds which would be set up with a course and video equipment for spectators to view the race from the pilot's view. organising this required a Health and Safety plan and Event management plan to be produced. In the end the event was cancelled due to rubbish weather. So as not to waste the effort used to produce the plans, I am keen to share them here in the hope that they save someone else a bit of effort organising similar events.

RC Glider NiMh Battery Pack Monitor

Le Thu 03 March 2016

This article describes a small battery monitor for indicating low voltage in a 4.8V NiMh battery pack as used in radio control gliders. The circuit is based on the Maxim 8211 voltage comparator chip.

12V Lead Acid Battery Monitor

Le Wed 03 February 2016

Both the ROV base station and the FPV base station I use are set up to be powered by a 12v battery. I was a little concerned that running these rigs for extended periods was exhausting the battery and dropping it to levels that could potentially cause it permanent damage. I needed a battery monitor that could warn me when I had used more than the battery could comfortably deliver. This article describes the 12V battery monitor I devised for the purpose.

Modifications to the Dragonfly Glider

Le Mon 25 January 2016

Several years ago I bought a Dragonfly Glider from HobbyKing..... I was drunk at the time. It looked so pretty and the built up wings kinda fragile so it remained in its box for several years. I finally decided to assemble it the other week and quickly came across the horror stories from other owners on the RCgroups discussion threads. The plane had some pretty big design flaws in it among them were teh wings collapsing and the motors burning out. So based on their ideas and suggestions I modified my Dragonfly in the hope of avoiding the problems and failures the other owners had encountered.

Fun with TS832 Video Transmitters

Le Tue 06 October 2015

TS832 video transmitters? What can I say about them. Based on what I have been taught as a kid which was "If you've got nothing nice to say don't say anything." this is going to be a really short read.

Installing a Dianmu OSD and FPV System in an Electric Glider

Le Tue 06 October 2015

Quite some time ago I purchased a Dianmu OSD (on-screen display) from HobbyKing. The Dianmu OSD also includes a flight controller with auto-leveling and return-to-home functions. It sat in a box for quite some time before I decided to mount it on my large(ish) electric Fox Glider. This page describes the connections between the various onboard electrical components.

Rotorcross Racing

Le Fri 18 September 2015

On the 13th of September 2015, the local model airplane club hosted a multirotor racing event. Using my FPV receiver I hitched a ride on the pilot's video feeds. Here is a compiled video of the thrills and spills of Rotorcross.

Custom RC Desk Pilot Scenes

Le Sun 08 February 2015

With a few rough python tools now to hand and visions for new worlds I have been building customised scenes for the RC Desk Pilot simulator. This page is where you can download these new scenes and get an idea of what they will look like.

Creating New Scenery for RC Desk Pilot

Le Wed 24 December 2014

I was browsing around to see what radio control aircraft model simulators were avilable when I came across R/C Desk Pilot, which I felt was a pretty slick little simulator. Unfortunately it only had one scene, so I picked at it a bit and found that it was possible to make new scenes for it. This tutorial / guide explains the process of building a new scene.

Component Model Library

Le Thu 07 August 2014

During the process of designing stuff I have built up a library of digital models of purchased components. This webpage provides links to the various models that I have created so that you can download and use them in your own creations. The models are in Blender and OBJ formats.

A Simple DeltaWing

Le Mon 19 May 2014

This is a little DeltaWing project I adapted with the addition of some 3D printed parts. The original designs came from from the websites referred to which include videos on how to construct them and demonstrate them in flight.

Quadcopter V2 - Quadcopterus Robusticus

Le Sun 13 April 2014

This is an update of my first crack at a Quadcopter and has features such as metal landing skids which make it somewhat more resistant to my rough piloting skills.

Quadcopter V1 - The Hulking Quadcopter

Le Fri 20 September 2013

This was my first shot at designing and making a quadcopter. It worked well enough but was a bit vulnerable to my crappy piloting skills so this design was soon superceded by Version 2 which is also described on this website.
