HAHA, WHOOPS! I didn't mean to sound like an ass there. I actually did find the thread for you and copied the link, but apparently I forgot to paste it in my post. Sorry I made you do extra work there. I didn't mean anything bad by that.

It's a GREAT antenna, though. I made 2 by myself. They turned out really well, but my takeoff angles are all outta whack. The antenna works really well and is tolerant to build mistakes. You'll love 'em!

Of course I'll balance the prop afterwords.

Doesn't matter how balanced the prop is, if you can't ensure it sits centered on the shaft
which is why the hole matters.

For those running Dragon Link, what length of receiver extension will I need if I want to place the receiver in the fuselage, and have the antenna elements on the vertical stabiliser? My options are:

18"
24"
30"
36"

cheers,

Sub.

The shaft does not touch the inner hole on my prop, the adapter presses against the outside rim.

You're going to have to show a picture of that, because it doesn't make any more
sense this time, than it did the last time you said it. If there's no contact with
the shaft, then any time you tighten the adapter nut/spinner down the prop
could be offset in any direction and there's no way to balance that.
APC supplies adapter rings to make the hole smaller so it fits the shaft.
If your prop doesn't have that and the hole is too big for the shaft,
then it's not suitable to your application.

Ok maybe I'm being dumb again. I'll take a picture a little later thanks for the help.

I was considering doing exactly what you did... or I was going to just have my antenna on the tail boom to avoid the run on coax. You aren't concerned about any of the cable loss? Just curious if you feel that the benefit of having it on the tail outweighs the drawback of the length of coax

The VTX is mounted flat on the area behind prop. The antenna is taped along the entire length of tail boom to avoid snagging and it is taped in front of the vertical fin all way up to the antenna.

The antenna itself is taped to top surface of elevator.

Lots of tape to hold it in place and I have hit branches with the antenna without any damages at all.

Any bad performance due to ~50cm cable??

Not as far as I have noticed - no glitches, no harmonics, no nothing
(VTX @1280mhz and Spektrum DX7 radio)

Yep, I think that's how I want to set mine up. Do you have a pic of your rx installation?
