Sim binding problem.


Senior Member
I am building my first quad copter and before I put it up in the air I want a simulator to practice on. I downloaded the old version of the heli-x (because it is free) and I have no clue on how to bind my transmitter to it. I am using a 9XR transmitter a windows 8 computer. could you guys please help me bind the to things. I am also open to any other free sims.
