The first Saito FA-30 from 1979. Over the last 50 years the first noticeable factor is the modeller himself. No gender bending here as the point to which I will allude is purely man’s domain. .

Ajay Models have sent details of the Titan ZG 26SC - a new 26cc petrol engine from Zenoah. Suitable for models in the glow range of 1. 20-1. 60.

At last, a single cylinder four-stroke of over 120-size. . . at a decent price, too.

This article was first published in 2006. I take no responsibility for the initial idea to build a pulsejet powered model - my good friend Bryan Passey is to blame for the inspiration. Always reminiscing about flying pulsejet powered control line speed models, he tried to get me to build and fly one. Frankly, though, a 1.

The Graupner Monsun pulled by a happy engine, a few simple steps should ensure you maximise your flying time. The great thing about modern glow engines is their reliability. Some engines of thirty years ago were as reliable as their modern counterparts, but production techniques were less advanced, tolerances varied, and the chances of getting a duff one were certainly greater. Today, with better metallurgy and the introduction of CAD coupled with CNC machining, the modern engine is a precision item and a thing of wonder.

The model diesel engine is very close to my heart, so I'm always pleased to see a new one appear. I was eleven years old when I saw my first, this being when my very enlightened secondary school woodwork teacher started an aeromodelling club. Imagine today's angst-ridden teachers showing such initiative, with their hand-wringing fuss over health, wealth, safety and sorcery in this litigious age! Wandering aimlessly around the playground circa 1963 I became aware of a burping, rasping noise that turned out to be a small diesel running on a test bench outside the woodwork shop. A gaggle of curious pupils crowded around the teacher as he fiddled with the tommy bar, coaxing the engine up to speed.

Similar in appearance to Enya's popular 41 four-stroke glow engine, this rather unusual hybrid is an interesting beast. Supplied partly assembled with cylinder head only lightly affixed, pushrod tubes loose in the box and rocker cover similarly detached, it's clear that this one's aimed at specialists and collectors who know one end of a conrod from the other. As we discussed in the last issue, the general construction is up to Enya's impeccably high standard yet, as always, the proof of the pudding is in the eating. Stay tuned, then, as we seat ourselves for dinner and prepare to savour every mouthful of Enya's brand new four-stroke diesel offering.

Having been a modeller for well over 30 years (and an engineer for a lot longer than that) I’ve built a fair number of models but have never made an engine for one. Despite the fact that there are a number of plans available, I never seemed to get around to it. However this changed when I read Alex Whittaker’s article in RCM&E concerning his Firefly project. I admire anyone who tries to have a go at something a bit more adventurous, and I was sufficiently tempted to give the Firefly a go myself, particularly as Alex was asking for volunteers to try the drawings out and machine a working prototype.

Last month we left the workshop having completed the cylinder head, barrel, liner, crankcase, bearing, and backplate of this feisty home-brew . 46. We’ve established that nothing so far has been that taxing in terms of manufacture, and I’m pleased to tell you that the same ease applies to what’s left. So, let’s crack on and get it finished.

Until now, plans for DIY engines have tended to be of smaller diesels and maybe the odd 2 or 3cc non R/C glow. However, the Firefly . 46 is the first forty class, two-stroke, R/C self-build engine to be published in a generation. In the UK, I can only remember the Jones, some decades ago, and that was a sixty, and even then you had to buy the plan.

When asked to write this feature I was very wary, if only because this is the one subject that's almost guaranteed to put the cat amongst the amateur industrial chemists out there, with almost everyone having an opinion on the subject. The problem with glow fuel is that we think we know more than we actually do, and in truth reading the instructions supplied with most model engines does little to clear things up. For years the importer of one particularly well-respected range of four-stroke engines remained completely at odds with the manufacturer, countermanding their advice. The supplied instructions were very clear in that they demanded only synthetic lubricants in the fuel, yet the factory instructions were rubber stamped 'Use Castor Only' in bold red typeface, leaving the buyer between a rather imposing rock and a very hard place indeed, with similar paradoxical examples to be found elsewhere.

Even apparently simple things, like starting an engine, often assume a good bit of inter-related background knowledge. Of course, the problem for the newcomer is acquiring that know-how quickly. So, I want to look at the underlying fundamentals one by one and then go though a typical and practical start-up procedure step-by-step. Buckle up tight in the back now! We’ll be starting a standard sport glow engine in the modelling equivalent of the missionary position.

Glance at the picture on the right there and there's no need for me to tell you that the subject of this review looks pretty striking in blue. Actually, it's very blue, and to all intents and purposes is a typical, nicely made, Chinese engine like all the others in this category. This is no bad thing, for without such Far Eastern manufacture the range of engines available to us would be very limited. The Chinese have been hard at this game for a couple of decades now and their engines are arguably amongst the very best out there.

Welcome to the second part of my JBA 52. I covered the basics in Part One, so I'll now move on to how it performed. Bolting the JBA 52 to my trusty (if very oily and battle damaged) test rig, I affixed an APC 11 x 6" glass nylon propeller to the business end. Since there’s no plug supplied (black mark, I hate that - it's like buying a car without a steering wheel; useless 'til you have one) I fitted a trusty Enya No.

For me, the initial appeal of MVVS petrol engines is that they’ve been designed exclusively for use with model aircraft and model boats. They’re not a revamped leaf blower / chainsaw / general hand tool engine or a mishmash of parts sourced off the shelf, assembled and then presented as an aero engine. For some reason the odd modeller will point to the carburettor used on an engine to indicate that it’s a ‘convert’ engine, as hand tool engines all use this type of carby. Not so, actually - the carburettor is almost always out-sourced from quite a few specialist manufacturers.
