Post subject:	2005 Epson環保嘉年華-- 環
香港環保促進將會在2005年1月30日於灣仔運動場舉行一個全港中小學生手擲滑翔機比賽，並邀請香港遙控滑翔飛行協會協辦該日賽事。為了此事，我們一班幹事在上星期五舉行了一次特別會議，為是日活動進行了一次簡單之討論及作初步分工。我們協會將會為當日比賽訂定賽例，以及為大會任評判。賽前兩個月，亦需為參賽講解有關滑翔機之飛行原理與制作。 YC 正在為此搜集資料，阿堅亦會在準備一兩架標準樣辦機，在講解日給參賽參考。日後若有更詳細資料，我會在此再為大家報告。是次比賽主要參賽對象為全之中小學生，目的為希望透過生動有趣的方式，提高香港青少年對環保問題的關注，並鼓勵他們發揮創意，以既新穎且實用的方法，設計出具環保意念的模型。該次活動亦能激發青少年對環保科學之興趣，更能提高參賽隊員對氣流力學之認識，箇中教育意義甚為濃厚。

可以參考中國比賽賽例，因為他們每年都有比賽。同時他們有比賽用飛機套裝可提供參考。

今個星期六上午9:00-12:00 在城市大學有一個簡介會，由 YC 及阿堅主持，到時需要有約十個幫手。主要工作是在小組討論時幫手向老師或學生解答一些飛機制作問題及飛行原理。有時間出席幫手的請與我聯絡。 Ken 9033 9701

我估 EPP 算唔環保物料。咁 Monokoke 或 Oracover 之類物料環唔環保呢？好多DLG都會用這些煬膠。其實我覺得用 Balsa 木仲唔環保，要斬好多樹！

Plastic materials are not, and they make pollution since they were being produced. We only use just a very very small amount of wood for modelling material. Compare to those who cut down a whole tropical forest for fuel and building material, I think wood models are less harmful to the environment. http://www.mat.uc.pt/~pedro/ncientificos/artigos/techbal.html One said that if you are going to cut a 100 years old tree to make a piece of furniture, then you must use that furniture for another 100 years. I totally agree with this. Environment protection is to treasure everything our mother Earth gives us. (ahhh. . . I feel guilty when I think of my composite sailplanes . . . ) p.s. Anyone can tell me how to use "CD/VCD/DVD" to make model airplanes

Hello Ken, How about the glue? We are used to epoxy and CA but do you think if they are acceptable? I just can't imagine using "rice+water" to build my model.

We are getting more and more environmental-unfriendly planes with all these stuff: plastic, foam, epoxy glue, glass fiber, kevlar, dynama, etc... I still remember I lost my Shooting Star years ago in Fei Ngo Shan. After a year lost in misery, it was discovered by a fellow pilot and emerged out from the bush again. The fuse body is intact (made of glass fiber -that's environmentally bad!) and should be able to reuse again. The wing is basically intact but the wing's inner part with the balsa sheet sandwich was badly degraded (environmentally good!). The conclusion is glass moldies are environmental-unfriendly - may be the carbon (degradable?) fiber planes are better, mmmg... Anyway, we should go back to the good old days with our planes built from wood parts and glue them together using rice-water. By then, we might be able to get back our clean air and blue sky. Don't you realize we got choked by the polluted air all day up on the mountain?

曾經係 cable-TV discovery channel 聽到句slogan, 好似係: Use only for our need, not our greed. 用EPP唔環保, 用木都唔環保, 要斬樹, 兼夾glider唔係our need (只係滿足我地既玩物慾). 可能真係要用蕉皮來做. 不過, 入返正題, 協會真係要預定 D 小朋友問"用木造機係咪環保"之類既問題啦...

很多同樣的問題我們已在過去幾次與環保會開會時提出過。這次比賽的主要目的是要令學生知道什麼是循環再用物料。大家不要將循環再用物料誤作環保物料。 EPP, Monokoke 或 Oracover 之類煬膠, Carbon Fibre, 膠紙, Epoxy, 膠袋, 油性噴漆....都不能用。他們在本星期六舉行的簡介會，就是要令大家更清楚比賽及解答問題，大家有空請出席，到時又可以幫忙。其實 CM 可以不用漿糊作膠水，現在很多文具店已有賣白膠漿，煬膠可以用絲巾或薄紗絲代替，上色亦可用水彩。其實世上有很多物料是可以用環保物料替代的，若真的沒有，大家亦可考慮一些循環再用物料。這次比賽很有意義，所以協會才會盡力協助。

聽日又要去城大教D小朋友設計飛機﹐唸起自己都未設計過﹐就整隻企業號滑翔機試下﹐剛剛試飛完﹐都算幾定幾浮。
