ORIGINAL: R/C Art
My Futaba book on my 7C says to place the antennas as far away as possible from each other and at 90 degrees to each other. The picture shows one antenna on the side of a fuselage and the other across a bulkhead ( neither one being vertical)......another picture shows a heli and a similar arrangement as my installation.
When it comes down to it - there are only 2 antennas and they will always be on the same plane relative to the receiver - what you are talking about is relative to the model. And that is where the debate lies........
Another consideration is surrounding metal such as what the front of this model will have totally enclosing it and also the big metal power plant up front which can block the signal if the receiver is too close to the front of the plane. And then there are all the flying and landing wires, not to mention the squirrel cage of a landing gear.
Oh, and don't forget the three pairs of control cables going to the tail surfaces.
An interesting conversation, isn't it?
Oh yeah.........a real "cliff hanger"!
