He will get the same range regardless of where he is. 2.4 is immune to nothing but the signal hopping keeps the system on a clean signal at all times. If this was a 72 MHZ system I would agree with you.
Not true.
<span style="color: rgb(255, 0, 0);">It "keeps" hopping within a rather narrow range of frequencies,</span> that often get swamped by other 2.4gHz devices, especially in residential areas.
I've seen this happen with these particular systems when both multiple WiFi access points are fairly close by and things like Microwaves are turned on.
The other devices swamp the entire spectrum that 2.4 devices use.
Don't assume that "hopping" solves all of the problems.
At normal flying sites the risk of this happening is MUCH MUCH lower because you are not as close in to the emitters.
There are over a million frequency combinations that out equipment can lock onto. Not exactly a small spectrum. I would love to know where you are getting your information. To interfere with our systems at all a signal has to have the same frequency, encoding and power level! That just really dosent happen in the real world. The bodas do have to be horizontal for full range. That way they are most exposed to the signal. Imagine running water in a rain gutter being the signal now position a slender object into the water lengthwise with the direction of the water. Not much exposure. Now turn it sideways, much more exposure. Now the battery issue, most batteries emit a low frequency electro magnetic field. Having it that close the the RX is a bad idea. See the way the servo wires are twisted on the Hitec digital servos? Its because of this field and twisting the pos and neg wires reduces it's effect. When I worked for Lockheed, anything we built with DC current had twisted wires and there was even a spec on how many twists per inch per wire gauge.
Jose, please offer expainations on your differing opinions as I have always done. Your findings don't really add up to me. Then again I have 15 years in RF experience and currently work at a company called Randtron Antenna Systems. I suggest you look it up.
