There is no doubt that the XPS system when it first came out had serious problems, some people got the system to work, but they are in the minority, hence Graupner recalling the IFS system and refunding monies, companies like Grupner do not do this usually they issue a credit note or upgrade the system the unusual step of refunding indicates their belife that the system was not viable and contraveaned the strict "Customer use Regulations" in Germany.

The new system that does have the capability of hopping between channels I am sure is a much better system, would I buy it, NO, I do not like being used as a Development Engineer with a system that could have cost me an airframe, once bitten twice shy, in fact I now will not buy anything Graupner as they argued the case with me until others sent theirs back, I think it was the various threads and Forums that I sent links to them for that finally convinced them.
