Default DX5e range test mode- what's a good distance?

I have a DX5e controlling a 60" trainer sporting an Orange RX with a satellite RX.

In range-test mode, off the front quarter of the plane, I have good reception out to about 200 feet- but I have no idea if this is a good result, middling, or not that good?

Since, in the DX5E manual page 10, Spektrum suggest about 90 feet I'd say you're doing amazingly well.

Several years ago, the now defunct RCReport magazine did tests on the 2.4 Ghz radio systems, including Spektrum and Futaba radios. Their range tests with the receiver located inside a full scale airplane with GPS location system showed these 2.4 Ghz radios have a line of sight range of about three miles. That is far further than the model can bee seen visually.

As for the Orange receivers,

Range is generally not a function of the TX, the RX is mostly what counts.
Orange RX----some swear by them, some swear at them. Of course the same can be said of stock Spektrum RX.

I am approaching the orange RX with some skepticism. If I develop doubts about it, I will put a spektrum in there- but would need to scrape up the cash to do so.

As Flydiver says range has a lot to do with the RX...so the fact that your Orange Rx range tests over twice as far as Spektrum expect their own RXs to do sounds quite encouraging to me.

And since I've still not had any problems with any of my Orange Rxs I'm firmly in the "swear by them" camp .

That might be common on these range tests. The name brand radios tend to list their range testing as a minimum.

As for my DX7 and AR7000 receivers, I can walk to the edge of our field, about 100 steps or so and still get solid range. That's considerably more than the specifications call for.

Default Receivers

I saw a youtube video yesterday where the Horizon Hobby guy was defending the AR600 receiver.. His main point was that the antennas needed to be oriented right. One antenna needed to be running forward or aft and the other, up and down (towards the wing or landing wheels) He asserted that having them parallel or worse, crossed would cause problems.

Lol this is one reason why I am cautious and will be using 72mhz for most of my planes.... What you are stating is that you gotta play with the antennas like if they were RABBIT ears on a UHF or VHf band ....

The shower to stay clean but cigarette smoke coating residue after a long day theory.... Nevermind that.... Anyways I thought these receivers brown out from irregular voltage fed from the ESC...? Just curious?

LOL!!!
That's the point, those two little antennas ARE miniature rabbit ears!
Which is why the quality receivers use one or more slave receivers with their associated miniature rabbit ear antennas, to make certain that at least one of the receivers is receiving a good signal.

Yeah
I've seen three model crashes at our club field this past year because of the BEC on those ESC's overheating and shutting down the receiver. Take a look:
http://www.wattflyer.com/forums/showthread.php?t=63779

Either go for the Castle Creations ICE series of ESC's (or similar types) with the switching BEC's, or go for those external switching BEC's such as Castle Creations or Common Sense uBEC's. I've got both, and they have been flawless over the past four flying seasons on six different airplanes.

Max power to the antenna when you are at right angles to the antenna, my TX antenna is always bent to the left or right so the goal is to at all times have one antenna pretty much the same way.
