hiko you could route the wire round the NB circle rather than dangling at the rear,

if the diameter permits that is..

Phoenix


I've submitted the photos of my 22" Nutball to Phoenix (RC sim) as per their instructions. Now wait and see.

Thanks for the antenna info I thought it had to be in a straight line I will route it around the edge
Uberjay
Some of this delivery problem is mine They said the delivery could take up to 45 days when I ordered.
I thought wow that long and didnt start enquiries until the 45 days were up and then I find out that the tracking has expired Lots of learning for me here!
They have promised to do an investigation for me so I live in hope

You're welcome Hiko.

Ideally straight is the best, but around the circle is going to be quite close in reception effectiveness, being in a circle should make it quite "directional effective"

In other words, and w/o getting too technical a straight dipole antenna like those will pick up signals better from most directions only when placed vertically and static.

But another way of getting them to receive well signals coming from anywhere in 360 degrees...is

making them round!

See? the NB is good even when it comes to this matters!

I used to fly an old heli with its antenna like this...



Ridiculous but
a. it worked
b. it came stock like this
c. where else could you put it? running through the tiny tail boom along with tail motor wires? yikes...

So I guess one can even get away with almost anything if it's short range...

I already said that earlier Chris.. indoor-close proximity etc.

Also, let's consider that those helis (I have to confess I had one) are not exactly...you know..

But would you risk it with a "proper" RC plane that will fly outdoors and who knows in what radio environment?

I'd like to think I wouldn't...

been there..done those mistakes before, loosing control of my models has always been a scary scenario, always.

they often end up costing time, money and hope that nothing, or, and, no one gets hurt.

IMHO...not worth it, I wouldn't take the chances knowing what I know now.

Never shorten the antenna, the system is tuned to it's length, the signal being picked up by the end of the wire. What you can do for shorter range is wind the wire like a coil, never crossing over itself, leaving a short length hanging. Having the wire cross over is the same as cutting it short to that point.

Still, you should follow the radio manufactures recommendations for legal reasons for you own protection if flying near spectators, public locations or me.

Better still, install a Corona 2.4 kit and never have to worry again.
