Dear all,
The objective of holding a DIY F3F contest is to enhance our in sight on aero dynamic and craftsmanship as well as to encourage creativity.
To clear the ambiguous, I have set some basic principles for the event.
1) The model must be home made by the pilot himself
2) Safety will be the utmost concern, the Contest Director shall ensure the model is ‘Sky-worthy’ (like roadworthy of a car)
3) No limitation on the materials. EPP, balsa or composite fabric is allowed. You can use solid brass for the entire model if you think fit
4) Wing area, wing load and wingspan etc, shall adhere to FAI’s F3F rules. So you could make a 60 inches racer or a 3 meter warship
5) The majority parts of the model shall come from raw material (servos, push rod and rudder horn etc, are exempted)
6) Carbon rods or strip (those commonly available in HK’s model shop) for reinforcement is allowed
7) Downloading the airfoil from open resource is allowed (e.g. HN-354, RG-15 and H5N1 etc.)
Shift-made is allowed. For example, you can use your mop pole at home to make the tail boom. However, you could not use any part of a broken fuselage as the substitution in your new model
9) The wing joiner is difficult to make / build by newcomer. With a view to encouraging participation, you can use any wing joiner in hand
10) Using any part of other model as the plug for making mould is not allowed. For example, you cannot use the wing of a Mini-NYX as the plug to make mould.
11) If the pilot have a model factory, he could not use his factory product for this game (Ah Kin, I am talking about you !)

親愛的朋友們，
其目的舉辦 DIY的F3F比賽是為了提高我們的視線對空氣動力學和工藝，以及鼓勵創意。
要清除的曖昧，我設置了一些基本原則的事件。
1）自製模型必須由飛行員自己
2）安全將是最令人關注，該競賽主任應確保該模型是'天空，值得'（像道路上行駛的汽車）
3）沒有限制的材料。資源增值計劃，輕或複合面料是允許的。你可以使用實心黃銅為整個模式，如果您認為合適
4）翼面積，機翼翼展負荷等，應堅持以議員的F3F規則。所以，你可以讓一個 60英寸賽車或是3米軍艦
5）大部分部位的模型應當來自原材料（伺服電機，推桿和舵角等者除外）
6）炭棒或條狀（這些通常可以在香港的模型店）允許加固
7）下載翼型從開放資源是允許的（例如，為 hn - 354和RG - 15和H5N1等）
8）輪班制是允許的。例如，你可以用你在家裡拖把桿，使尾部的繁榮。但是，你不能使用任何一個破碎的機身部分為在新的替代模式
9）翼Joiner是很難使/建設的新人。為了鼓勵參與，您可以使用任何翼喬伊納在手
10）使用其他任何部分作為插件模型製作模具是不允許的。例如，您不能使用機翼一個小型尼克斯的插頭製造模具。
11）如果有一個模型試驗廠，他不能用他的工廠的產品為這個遊戲（阿金，我說你！）
