XPS and Giant Scale
Now that XPS has been out for awhile I was looking for some reports either positive or negative regarding its use in 50cc planes and up...any installation pics are welcomed as well...

RE: XPS and Giant Scale
I'm using "XPS" in a GP Ultimate / a "Planes Plus" 34% Extra /a GP Patty Wagstaff---All have spark/ignition engines---Works just fine!
FWIW---I'm also using the orginal "Toledo" stub antenna version TX module---

RE: XPS and Giant Scale
I have been using a 10 channel XPS receiver in a 1/4 scale (102") ME109G with a Quadra 75 gas engine on C&H ignition and have not had any issues. I am able to get the system to act sluggish during a ground range check at about 50' and at one particular spot with respect to the plane. In this location the large aluminum air tank for the retracts is directly in line with the receiver. As soon as I re-attach the antenna or release the low power button, the response returns to normal. The sluggishness also goes away if I move even a few feet from the left or right of that one position. Seems strange to me, but I am not able to get the system to act sluggish when I stand directly in front of the plane, putting the engine between me and the transmitter. I would have thought this to be the worst case scenario with the metal of the large engine (a Quadra 75 is pretty large), but it seems fine. I have not noticed any sluggishness in the air.

RE: XPS and Giant Scale
I don't have this system and I don't fly giant scale. One tip Ihave picked up across all the MFG systems is make sure you have enough battery to the receiver to hold voltage. All of these 2.4 GHz receivers are microprocessor based. If you drop the voltage too low, they have to "reboot" for lack of a better word and that can take a couple of seconds. I think the XPS can tollerate down to 3.5V which is VERY low voltage, but you dont' want it dropping below 4, for sure.
I am sure you you have plenty of power but keep this in mind. On 72 MHz systems, the receivers seem to fade momentarily if the voltages drop too low but they don't actually restart.
I am not giving you the technical detail, just the cause and effect. Make sure you have enough power to insure voltage to the receiver.
