RE: Correct way to install Futaba 2.4 617 rx
For the receiver mounting, I would just use Velcro.
For the antennae. They need to mount 90 degrees to each other. Look at them and you will see a "silver tip" sticking out the end of the wire. Those tips are the actual antennae and are what should be 90 degrees to each other. the coated wire between the receiver and the tip is not so important as to how it runs.
Many (including me) glue a piece of drinking straw or fuel tube to the fuse and run the antennae inside that. I like to have the actual antenna part sticking out of the tube but have been told it makes no real difference.
I just went out to take a photo but my camera battery is flat. Will charge it up and post one later if nobody else has posted a photo in the meantime.
