David Watson converts a pusher prop powered jet style model into EDF by employing 3D printed components.

During the 2020 lockdown I converted an established model design, Pushy Cat, from pusher-prop to EDF using own designed and printed 3D components. As an introduction to 3D printing, it was an excellent project. It even resulted in a practical flying model!

Alex Whittaker looks at some simple sheet balsa wood working techniques.

Perversely, although the flying field is open, the wind is light and the sun is shining, I have been back at my bench.

Danny Fenton concludes his build of a DB Sport & Scale semi scale kit.

I used a hinging technique that I first saw Brian Taylor use. I am sure it has been around since before that, but it produces a beautifully accurate, precise and free moving hinge, with the bonus that the piano wire hinge pin can be removed to allow disassembly right up until applying the final paint.

Danny Fenton describes his build of a DB Sport & Scale semi scale kit

Regular 'Make It Scale' readers may recall that I had purchased a DB Sport & Scale Auster Autocrat from an advert in RCM&E. The remit was for a fun model to try a few techniques I had been musing for several months. In fact, one had been on the cards for a few years! My mind works quite slowly sometimes but I do get there in the end.

Each time you assemble your favourite ARTF it's a good idea to check for wear and tear on the servo leads, especially where the wires crimp into the plug.

If the wires are starting to break, then it's time to replace the whole plug. You could make new crimps but it's easier to solder on a fresh plug

Paul Cox reveals a simple way to bring your receiver status light to the fore

Knowing that your transmitter is solidly bound with your model's receiver can be a concern if the receiver is buried in the bowels of your pride and joy and you’re unable to view the status light to give you comfort and confidence.

Joe Collicutt describes his finely tuned method of building from plans using Depron rather than balsa.

Lots of people have become used to using Depron sheet as a building material in the past decade or so and some have designed whole models out of the stuff. A typical example being the Ultimate biplane by Dave Royds, as featured in the December 2009 edition of RCM&E. However, I am not aware of many builders who have employed it extensively to make a sizeable scale model from plans designed for balsa wood.

Back in the old days, many plans had a materials list included on the drawing - and it’s been suggested that it would be good to reintroduce the idea. However, even if future plans do incorporate such a list there are thousands of old ones that don’t, leaving the builder to work out what materials are needed. The materials list of yore was only ever a loose guide, because some people use more wood than others. For example, one individual might cut a set of wing ribs from two sheets of wood by carefully interleaving them, whereas someone else might use the ‘solid block’ method of cutting them out, which uses far more wood.

My beloved, ageing 72” span Harvard, built more than fifteen years ago from a Flair kit, hit the ground like a dropped jigsaw. We’d been through a great deal together over the years…balmy summer evenings, winter snow. . .

Anyone researching electric flight for the first time can’t help but notice the advice to buy a wattmeter which appears in so many magazine articles and forum posts aimed at beginners. Let’s look at what they do. Quite simply a wattmeter is an electrical measuring instrument that is connected within a DC electrical circuit and measures and displays the current flowing in the circuit and the voltage present. It also multiplies the voltage and current together to present the watts consumed by the circuit.

3Dprinting may seem like a fairly recent innovation, however it’s been around for longer than you might perhaps imagine. The first 3D printers appeared commercially in the mid 1990s, but priced in the region of £75,000 they certainly weren’t cheap - you were in Ferrari and Porsche territory. The technology was developed in the 1980s, Chuck Hull being accredited with demonstrating his SLA-1 printer as the first commercial example some 34 years ago on March 9th. His intention was to develop a machine that would be capable of speeding up the time it took to create prototypes as using a one-off machining process was expensive in terms of both time and money;the ability to print an item in just a few hours represented a major breakthrough as you can imagine.

JAMMIN' “Whilst removing a propeller from my model I encountered a jammed collet-type prop adaptor”, writes Henry Leong from Brisbane, Australia. “This wasn't the first time this had happened, and the subsequent firm, twisting and tapping required to separate the tapered outer collar from its shaft is always a worry, risking damage to the airframe. What I needed was a set of claw-like fingers, precise enough to pull the outer collar whilst a central finger pushes the collet shaft in the opposite direction. Memories of my dad's crank pulley removal tool flashed past and I came up with an improvised tool that would act as a very effective collet puller, based on a (cheap) skeleton-type caulking gun from my local hardware store.

My home-brew winter project has reached the stage where the woodwork is essentially complete, bar some final gluing up, and it’s time to cover the model. Since the aeroplane is a sports design I’ve decided to use an eye catching scheme in a bright iron-on film. Now, before applying any covering I always perform a trial installation of the radio and engine, including all control runs, as it’s all too easy to damage a covered model during this process. Also, it’s very much easier to cover components whilst they’re still flat objects on the bench.

Visit any flying site and you’ll notice that, whether i. c. or electric powered, the majority of models being flown are single-engine. That’s not to say that twins aren’t seen, but for many the journey into multi-engine installations is a trip into the unknown and, therefore, often avoided like the plague! One reason for this is probably the cost, as models with multiple power units are, by nature, more expensive to build and operate.

YOU WILL NEED: 1. A well ventilated room 2. A variety of cyano glues 3. Materials (wood, plastic etc.
