How the transmitter sits on the bird

Use the mount that matches the hardware on your transmitter. These photos are from the Marshall site.

If you use a leg mount

Every transmitter ships with a tail spring. Take the spring off for a leg mount. Keep the spring so you can change back to a tail mount or a TrackPack later.
