Fly Sky reciever question
 

I just bought the FlySky GT2 radio as an upgrade for my old RC10 and/or tc3 and need to connect my servoes. What connector do I need since my OLD servoes still have the 3 pin Futaba plugs. I have the plug from an old Hitec serveo that I cut off of one that seems to fit. Are they all the same connectors now or do I need a spefic brand/style? Sorry for the neub type question but my stuff is pretty old.

Thanks
Mark
