Your a very defensive young guy and I admire your tenacity. When I said XPS is still the same box as it was two years ago I meant that fundamentally the OS is the same. The XPD is a bell and the new cases are a whistle. But the guts of the device, the spherical nuclear all encompassing antenna etc are the exact same.
The one and only issue with XPS that I see from a user point of view is that it is a single locked channel system with no antenna diversity, no possible way in the world to dodge interference or skirt it somehow.
The other systems (ASSAN is the exception but they dont claim to hop or try to get out od the way) ALL HAVE DIVERSITY.
If XPS would do what the manufacturer says it can do and show with repeatable certainty that it is a flexible and agile 2.4 Ghz radio transmission device perfectly suitable for RC use in all types and sizes of model airplanes then I will take my hat off to JD and the company. Competition is great, it drives technology, it creates a buyers market and normally it gets the customer a better deal in the end. But sometimes there are people who sell little bottles of snake oil at exorbitant prices claiming to cure anything and everything when in fact the oil in the bottle is for frying turkeys in.
As for testing the resistance of the others to the same test I have done it a dozen times but what I cant do is soak the entire band with sufficient noise to make even the slightest impact. I dont want to spend another $500 on the jammer as that is just wasting my money on a ten minute show and tell and then what will use it for?? Sort of a dumb device to be carrying around in my RC box I think.
So if your willing to let me show you FASST and SPEKTRUM working in the exact same conditions as I tested XPS I will post the video for you. But realize that with a single channel Rx (XPS) I will make it go into fail safe. The others will work perfectly because in the case of SPEKTRUM it has the second channel miles away from where I can swamp it and FASST just passes through it as if it does not exist.
I will try my best to get the video done tonight and post it for you. |

Just for the record....Spektrum and FASST haven't done anything more fancy than XPS in regards to upgrades.
Spektrum--under the table upgrade that changed how it looked for freqs when a brown out occurred. Did nothing to stop the brown out or decrease its value. If it wasn't for the R/C forums no one would know you could do it.
FASST--Out in the open (good job there) they will reset your radio off the Zguid but that is still clouded in whether or not its a perm fix. You have other countries getting a different version of the fix than the US. Which is better or correct?
I would definetaly say that of these 3 manufactures that non of them has done a superb job of fixing their own issues.
As for your tests Kiwi........don't buy more equipment. Just post the vid of you doing the same thing you did to XPS to the others. so that would mean putting Spektrum on and putting the same power on one freq. Then slowly bringing it up and from the side etc. Then doing it again to the other freq it uses. For FASST I would just pick a freq in the front, middle, and end of the spektrum and do the same thing.
I expected these 2 to pass, but wanted you do it just to make sure that there wasn't something intrinsic in the test that may cause all to fail. Posting the video seals the deal just like everyone says it does with XPS.
