Do you need a model flying licence to fly the plane in the park?

BarF1

looks like Eflite battery ... kV ? Prop size ?

fy789: no I will be using a pair of 7" APC props (propellers). EDF (ducted fan) looks good but the efficiency is terrible, and I would probably need 4 of them to fly which is going to make the plane very heavy.

fm9610: I don't think so, as I never get in trouble but getting surrounded by kids. I need crowd control.

BarF1: No definitely not E-flite. Their stuff are overpriced and the quality is average. The battery brand is Zippy-K and it's from an online store called "HobbyKing".

need a nice paint job, maybe zuesel can help?

rockypath

can it actually fly?

saotome

ACC-HE: Ya I am a terrible painter, help anyone?

Rockypath: Will it fly? I don't know yet. But here is a flight video from last year before the conversion.

報告各位看官:首航己告失敗。

死因係CG太後，之前較好既CG位置不可用。估計應該係推力線相反既關係，機頭抬頭嚴重，升降陀全開無效。

可幸既係保住左機翼，機尾同部份機頭。

遲少少post番段炸機片

當初整後推版既目的就係要搵出完美 CG 點，點知原來摩打改位之後之前定既 CG 已經唔合用，慘痛教訓！



各位認為 CG 要推前幾多呢？摩打進角都可能要改…

saotome

終於飛得起

經過上次慘痛既教訓，今次將 CG 向前移 1.5"，摩打偏角向下 5 度左右。狠起心再掟佢上天，不成功便成垃圾喇！！



不過降落速度實在太快，又冇設定 flaps 或 air brake，衰收尾！
好彩除左甩左隻假引擎之外，一樣野都冇爛

可能要考慮裝轆…

好好睇! 好靚好靚!
