The OLD Falcon 46 should not have been called a Falcon as it really was an old Hawk II (a much different heli then the current Hawk Sport) that had a different motor mount and a longer tail boom to accomodate the longer 600mm blades. The Falcon 46 really has little in common with the Falcon SE or the SEV2.

You have done away with the 8mm mainshaft system of the old F46 and installed the far superior 10mm system from your Hawk Sport. This shaft is a fair bit longer, so you will find that the control rod lengths from the Hawk Sport will work very well. Note, be sure to use the complete collective system from the Sport as well because it uses the longer elevator A-arm that is also required.
