- Where to run your radio aerial when
using a 35MHz radio
There is quite a bit of
misunderstanding about the aerial on the helicopter that is connected to
the RX (Radio Receiver).
Far too many people
believe - WRONGLY - That it is fine to just wrap it round and round the
Doing so will cause you
to loose contact with your helicopter a lot nearer than you should, and
an out of control helicopter is a VERY DANGEROUS THING to have.
The radio manufacturers
will tell you that it really is essential to have at least 9 inches, and
preferably a bit more, of STRAIGHT aerial wire. This should be
either the first section or even the last section, which is exactly why
most helicopters come with a length of plastic aerial tube that
typically fits to the skids. This tube is about 9 inches long, and
therefore forces you to have that first section of your aerial STRAIGHT.
If you use this aerial
tube at the start of the aerial that is fine, and you can then wind the
rest of the aerial up the boom tube if you wish. I personally use
a longer tube, and then wind all the rest of the aerial back around the
far end and tape it there. Then I connect the back end of the tube
to the rear end of the boom support.
NEVER THINK ABOUT CUTTING THE AERIAL, THEY NEED TO BE A CERTAIN
LENGTH... That also applies to 2.4GHz aerials as well
