转：欢迎来到麦克的像真模型世界

转者注：这可是个牛人啊，而且专门做小尺寸模型，虽然不是遥控器的，但是自由飞的魅力也很大！

The purpose of this site is to show examples of free-flight flying scale models from the UK, together with (hopefully) useful information, hints and tips for fellow builders. If newcomers to this fine hobby find encouragement here, then so much the better!
My main interest is in traditionally constructed scale models, built using a balsa framework covered in tissue. Motive power is usually electric, CO2 or the traditional rubber strip motor. It is years since I built a model with an internal combustion motor in it - nowadays there seems to be a move towards quieter, more "enviromentally friendly" power units, so CO2 and Electric are becoming more popular, and there are even compressed air power units now available. The appearance in recent years of Rapier solid fuel propulsion units has also lead to an entertaining detour into the wonderful world of small free-flight scale jets.

建立这个网站的初衷是展示一些来自英国的自由飞像真模型，也展示一些模型及其制造者的信息。如果这方面的新手由此被拉下水，那就太好了！
我的主要兴趣是用传统公益制作像真模型（用轻木做框架，棉纸蒙皮）。动力通常使用电动、二氧化碳（翻译者注:猜想是干冰气化产生动力）、或者橡皮筋动力。从我开始做内燃机模型至今已经有些年头了，现在看起来动力在朝着更安静、更环保的方向发展，所以电动和二氧化碳驱动变得越来越流行，同时现在也有了压缩空气引擎。近年来固态火jian发动机（翻译者注：不知道怎么翻译，从后面看就是火jian发动机原理）也开始在小尺寸像真模型的领域应用。

我对干冰引擎非常感兴趣，看起来应该是很便宜的东西：只要有一个容器装干冰，并且能承受其气化压力即可。另外，不知道“Rapier solid fuel propulsion units”究竟是什么东东。不过这个牛人的模型做得太棒了。

The second shot shows how I extract the motor. In operation each motor is recessed 1/4" within it's nacelle. To remove the spent casing I pull the retaining wire away from the casing then insert a heavy guage wire through the nacelle inlet cone and push it out. The scale nacelle outer diameter did not allow augmented airflow into and around the motor. However, the motor mount has an 1/16" air gap around the motor and the inner surface of the nacelle is foil lined. I won't have any cooling problems.

Not seen in the pictures - the rear turret has twin 20 mm cannons made from one of those nylon tag tethers found on new clothing. They're rigid but flexible if I forget about them. Piano wire or pins hurt, these don't! More info. will follow as weather improves and I begin glide testing."

I can't wait to hear how it goes!

这段看得我晕乎乎的，从中得到一个映象，大概这种引擎是一次性的，喷完就没有了，所以飞完以后要更换一个内胆。有高手请指点一下

压缩的二氧化碳，当然一喷就玩完了
