Every Part on the plane is new. Every extension, battery, servo, even the 9Cap radio. I am using FM however and not PCM. With every servo unplugged from the reciever and plugging 1 reg servo into each channel, every channel is jumping. Its like I am transmitting it, however its doing it on every channel with 2 differant Txs and 2 diff Rxs, even on 2 differant channels!! I cant figure it out guys, do i need to be on PCM?
