之前整個條係E-sky 接futaba , 用來教仔玩
而家用DX7 做master, 因JR/ Spektrum Master 用negative shift, Futaba student 要用signal inverter 或 PIC 改PPM 輸出, positive shift 做番negative shift 輸出
更正: Spektrum DX7 輸出為 9ch , Frame 22ms, 9channel, positive shift 1.5V
及T7CHP 輸出為 8 channel, Frame 20.5ms, 8channel, positive shift 2V
所以只要接T7CHP PPM 輸出 致DX7 mono plug in 便可. 但要修改 T7CHP channel 排序
另E-sky 4ch 係可接 DX7 , 要修改E-sky channel 排序.
成功
