Yes, I can see the pilots moving himself foreward and backward to shift CG. |

唔怪之得有D鏡頭入面見個派樂伸左個膝頭出黎啦﹐無理由架﹐好阻風架渦﹐諗極都唔明﹐原來俾緊 up. 整到隻載得人既飛機﹐真係睇下都好開心﹐點解人地可以搞到呢D活動出黎架 ﹖除左錢外﹐仲要有咩野條件呢 ﹖睇落真係好過癮渦﹗ |

要收效果, 唔洗真人騎上去卦... 不如攪個遙控滑翔機定點降落賽, 由國金出機, 西九定點降落啦. 咁創舉既活動一定有電視台黎採訪. |

我覺得那些細路學生有這麼毅力，我們這班滑翔機手應該要學習、學習！ 我有一個奇想，就是造一架20米的滑翔機由飛鵝山起飛，然後滑翔降落在舊啟德機場上。如果載人有危險，可以考慮以遙控方式，接力控制。由飛鵝山山頂到啟德機場大約有5至6公里，飛鵝山的高度是500米，只要隻滑翔機的gliding ratio有12倍左右，這個構思是絕對可行的。況且如果風向適合，滑翔機還可沿山坡盤高，增加滑翔距離。至於接力控制問題，我們可選擇視野清晰的接力點，我估計只需兩個接力點就可以，如圖所示： 
這個創舉如果得到大機構的贊助如：國泰航空、民航處、匯豐銀行等等，應該可以為慈善機構籌得一畢可觀的善款，公眾又會對滑翔飛行這類活動有更多的認識，何樂而不為呢？ |

Sounds a great idea. Count me in. |

What is the current weight limit for RC models ? Is it 6kg or 9kg ? Do you think any of the companies will risk breaking the law on this project ! A 20 meter sailplane will be very heavy. Flying that plane across a build up area is not a good idea. What if someone else switch on their radio with the same band

Build one from Dr. Mark Drela's series and then get exposure with MIT University of USA as well as inviting Dr Drela to Hong Kong!!! |

Not a good idea. What happen if the RC plane landed on Choi Hung or somewhere eles? No chance to get the admission by gov I can say. Tsz Ming |

I would suggest flying to the waterfront of Sai Kung, and lands on the sea, it is much comfortable. Just like the paraglider flies to the abandoned field.

FYI, the max weight for exempted aircrafts is 7kg. Anything heavier than that will be considered as "real planes" by the CAD. Flying one with an on-board human pilot is only possible with an air-worthy (real) plane, otherwise it's irresponsible and probably suicidal. The way those Jap students do it, flying off a pier wearing a safety helmat and life vest, plane structure built with light weight materials and a breakable cockpit, boats following alongside, demonstrates a lot of safety built into the system. Much safer than flying an unmanned model over populated area I would say. I believe the CAD would not interfere with some folks jumping off a pier in a plane like costume, even if it flies a bit. And "a bit" can become 100m next year... and after you have done it for 10 years everybody accepts the status quo. Never do it over hard land, could get someone killed. |

你地呢幾日冇機放就發夢,我今曰己經親自去咗香港飛行總會間過,私人飛機在港內飛行,所有飛行器須到澳州驗機,因為佢最平!!只有三條民用路線.飛鵝山無份!!仲要係有意外是不會跌入民居, |

Of course there're all sorts of "kin stuff" up there, but hey, it's not about cheap and easy flying experience. Like JFK said "not because it's easy, but because it's difficult!" That's why those students did what they did. |
