DO NOT double the antenna back on itself. This in effect shortens the antenna. The folded back section will in effect cancel the signal received by the section where it is doubled. Let the excess hang out the back of the fuse. Do not fold or coil the excess at the RX for the same reason. The antenna should be straight from the Rx to the end, minor deviations are permissable such as routing the wire around the compartment, etc. Avoid running the wire near the servos or any large metal objects.
