Does the receiver have an antenna? If so, how long is it? Return to Top
Yes, the stock antenna is 8.5” long making mounting the antenna easy. What’s more, if you prefer a shorter antenna, you can carefully cut the Spektrum receiver antenna to just 3.6” – and not lose any performance. This way, you can keep the antenna inside the body.


So 8.5-3.6 = 4.9" to cut off!
