Company founder Gen Saito with one of his first model motors, a pre-war spark ignition unit. There will be few readers of RCM&E to whom the name ‘Saito’ is unknown: even those modellers who, like myself, have not yet bought or used a Saito motor will recognise the marque. Unlike the other ‘big’ Japanese model aero-engine manufacturers such as O. S.

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.

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.

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.

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.

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. .

A Cox control-line P-51. Cox were making live fuel powered RTFs generations before the current boom in ARTFs. Spring has sprung, the grass is riz. The blonde person has been having great fun with her brand new, shrieking-yellow strimmer.

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.

Weston's Alan Greenfield - note the Weston muffler fitted to this RCV engine. Weston UK confirmed at the Nuremburg trade fair that they will be the exclusive worldwide distributors of the RCV engine range going forward. It's good news for users of these unique British designed four-stroke engines now made in China. Weston UK director, Alan Greenfield confirmed that the motors will continue to receive full back up from Weston's considerable UK and U.

Saito have just unveilled something of a new departure for them - a 36cc four-stroke petrol engine! The Saito FG-36 is supplied with an electronic ignition system and a purpose-made aluminium engine mount. The carb' employs a diaphram pump for reliable fuel feed at any attitude and isn't sensitive to the position of the fuel tank. The motor will happily accept forecourt quality petrol mixed in a ratio 20-30:1 petrol to oil. We'll have a full review of the engine in the September issue of RCM&E Datafile Name - FG-36 UK distributor - MacGregor Industries Displacement - 36.

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.
