Just to make this crystal clear in my little head... ALL Spektrum RX's have the same range if they are in an airplane that has no "shadowing" issues, right?
But doesn't every electric airplane have a chunk of metal up front spinning the prop, an ESC and a battery to block signals?
And... can a longer antenna be aded to any "Park Flyer" Rx to help it see around shadowing?
(I think this is going to be a great thread NJS).
No all receivers do not have the same range. In fact the smaller units usually do have a shorter range, but it is irrelevant if the range is 1.7 miles for the AR6100 vs 2.3 miles for the AR6200. Both will provide you with far past line of sight vision for most any airplane.
So yes - smaller parkflier planes also have stuff that may
block signals like motors, wires and batteries. And yes some signals (frames/packets) might
The good news is it takes many dropped frames/packets before you start having issues. No RF link is 100%, period. So don't spend much time at night losing sleep. Since the plane is moving all the time it will be out of that shadow condition in a fraction of a second. This is why heli installations are so critical. In theory you could be in an orientation in hover that blocks the signal for a second or two. This would be fatal.
Yes you could add a longer antenna but the benefit is likely marginal and in fact you will likely cause yourself more issues. The receiver was designed and testing in the configuration provided. You are much better off to select a receiver with the airplane and conditions in mind.
For example if you have a carbon fiber fuselage - you MUST buy a receiver that you can get the antenna(s) outside of the fuse. That is why Spektrum makes an RX for just that purpose with two nice long whiskers that you place outside the carbon.
When you use the Flight Log data link feature on the Spektrum receivers (that support it) they will actually tell you how many lost packets you have. This can show a poor installation. That said you will be shocked at how hard it is to even get one lost packet. The systems are simply that well engineered.
Here is the quote from Spektrum:
Spektrum’s optional Flight Log is a unique tool that allows you to view the performance of your radio system like never before. With the revolutionary Flight Log, you can now quickly and easily view the real-time voltage supplied to your receiver, how many fades each internal receiver and remote receiver gets each flight, and if the system received any frame losses or failsafes (holds).
