早排Download咗Hitec Optic 6嘅Manual同Tutorial, 份Manual寫得幾詳細, 好多飛機操作模式都有解釋, 例如Differential Aileron, Flap, Landing Mode等...
Tutorial就比較Practical, 差唔多係Step By Step咁教每一個操作模式嘅Setup...
睇完呢兩份文獻, 真係獲益良多, 久唔久要拎番出嚟睇睇, 應該另有一番領悟...

Optic 6都有好多Function, 對我現時嚟講, 足夠有凸...
除咗佢係6 Channel之外, 唔知同Futaba FF9差幾遠...

房仔話Hitec喺外國好出名, 比Futaba更多人用, 香港就唔係咁多地方有得賣...
如果要用Optic 6個PCM, 一定要用番Hitec嘅QPCM接收, 我諗都唔係咁易買到...
PPM就無所謂, Futaba/Hitec個Transmit Shift係Negative Shift, JR/Multiplex就係Positive Shift, 只要Set正咗就用得, 都幾方便...
