Flying small model aeroplanes with rockets is a thrilling activity, one open to all, but in the last couple of years there have been questions about the availability of Rapier motors, and their reliability and performance when you can get them.

Although they are not now sold by model shops like the splendid 'SAMS Models', who nevertheless sell models for them, see:

Rapiers are still made by Dr Zigmund in the Czech Republic and available in this country. They can be collected at meetings or by personal delivery. The situation is not unlike that of the more powerful motors for model rockets. But, if you want 'em, you can get them, and the latest 2013 batches are well worth having.

The latest L-1 motors put out 100mN for 10 sec, giving my Swedish Lansen (above) a sparkling performance:

The latest L-2 motors are also pretty potent, and so far, I've had no blowouts. So we can build and fly with confidence!

 Welcome to the first of what I hope will be regular 'Jetex and Rapier related 'blogs'. As this is my first foray into the 'blogosphere' it will take me time to find my niche, so please bear with me.

These will of course be full of interesting observations about the modern 'small model jet plane flying' scene which will motivate a loyal cadre of enthusiasts to keep up with the latest news about motor availability, upcoming meetings and how to take part in what I hope will be a growing part of the free flight aeromodelling scene. Note the 'free flight' bit. I have nothing to say about those marvellous and sophisticated RC jets that we see showing off at meetings. However, free flight EDF is pertinent to our hobby and is one way of keeping our models flying. We shall see!

What with the winter weather – my own flying field is more suited to hydroplanes than aeroplanes at the moment – I have been designing some new models for the new flying season. These are simple 'semi-profile' models like the Cougar above  suitable for the latest batch of Rapier L-1 and L-2 motors.
