Default DX-7 Signal Shading Question...

Danny,

I'm installing a DX-7/AR-7000 system in a 90 size Seagull Yak and I have a concern about signal shading on the antennae.

The wing tube is aluminum and the primary Rx whiskers will be parallel to it approximately 3 inches behind, and about 1/2 inch below the centerline of it. One of the primary Rx whiskers will also be about 1 inch forward of the rudder servo. The secondary Rx will have it's whiskers oriented vertically ( up and down) on the side of the fuselage with one of the whiskers about 1/2 inch of the throttle servo and wire.

With this setup, how concerned about signal shading should I be? If it's not good to be that close, how far away should I keep the Rx's from the "shade"?

I've seen too many of the Spektrum units in action and I do have confidence in it but, I feel I need to ask for my own peace of mind.

Thanks!

It sounds like your receiver installation should be just fine. Be sure to range test before flight as described in the manual, but it should work just fine.

Thanks Danny.

It range checked fine at the house with the engine off. I even had a friend rotate the plane 360 degrees and at all imaginable angles. It's rock solid in the low power mode at way more than the recommended distance.

Life is good![8D]
