Hmm interesting, Because XPS inventor dragged his feet for two years US market claiming he could not get plastic module housing from Horizon, all the while he was secretly working with Graupner. .02

The Graupner 2.4G is not new I seen the German adds over a year ago. I also asked JEff H from Team JR at a early spring event if Graupner was using licensed Spektrum, he said no and made no comment as to what they were using.

The XPS creator has a long history of contraversial subject matter of the design claims on RCGroups/Runryder as well as RCU, Given the guys tactics to enter the market alone is enough for me to put his system last in line.


FWIW
XPS was also onsight at a recent Las Vegas electric event during weekend of 60th anniversary Airshow Airforce, They watched in horror as an XPS equipped Ducted Fan system flew out of site WOT straight an level. Never to be found. spextrum also went down in fairness and No one could verify to me an actual FASST going down. That event is about to get cancelled as taboo as a violent RF enviroment. The club is on a fact finding mission to documnet all problems from real pilot data input only, no My buddies second hand info. I'm awaiting their findings. The XPS guys had a Freq analyzer and said the airwaves were ablaze, speculating the Air Force was bombarding all radio freq out to Area 51, ....who knows. but interesting reading none the less. Do your own search, XPS is a very contraversial supplier of 2.4G
