Lake Reaper aerial rubber bung. This is used for covering the hole on the Lake Reaper which is left from removing the aerial wire from the AD1202, DE-104 handset receivers, and also if you remove a fish finder aerial. This is needed when you are upgrading/changing your AD1202 & DE-104 handsets to a new handset such as the Flysky, Microzone and DS600 single hand control radios and you want to cover/fill the hole left behind.
