Antenna Placement

Hi Guys,

I've got my Rangelink and done a few ground tests! (Awesome)

Now it's time to install the RX's and antenna's and I'm not sure of the best position? I'm guessing for the best performance it should be vertical.
(I also have a 900mhz Vid TX and a GPS on board. They are currently at opposite ends of the plane.)

This is what I'm installing it into....
Any ideas for the best antenna placement??

For the guys that have done it can you please post photo's of what you did.

Cheers!

Scott

A nice big plane

only for reference: (center wire goes up and the ground wire goes down)

Hi guys im having trouble trying to get my DX7 to PPM mode. I cant get the Red led to flash on the Rangelink.
On my DX6 it works, I just plug the pnp plug in the trainer port on the dx6 and power up the rangelink with 3slipo and all good.

But I just cant get the dx7 to work, any ideas?

Cheers if you can help

Is it a problem for inteferences that the RL-RX is 2 cm away from the GPS?
Isnt it better to take the long RX antenna from you and place it vertical at the end of one/any wing?

cheers

far away from VTX is good idea,but for the GPS no need,it work on rx mode.

Thanks for the info. So thats really not much power at all, I could run 800Ma battery for a pretty long flight.

Btw sid, works like a charm with the Dx6i. Just Plug and play :-)

That is ok,Alex, the futaba radio ,it needs a 10K pull up, because that is a "OD/OC" output, so need pull up make level convert...
