Default Re: Independent tests prove lack of frequency hopping with XPS

The issue here is that XPS DOES NOT HOP IN A USEFUL FASHION
Well, thats not what is bothering me in the first place. Its this: XPS seems to work most of the time well, but tends to fail in some locations horribly. See e.g. one case here in Germany - during a Pylon racing contest in Leipzig last month. Eleven pilots with FASST, two with XPS (iFS). Both XPS flyers lost all their planes - two per pilot - due to radio lockouts. In two cases not even the failsafe kicked in - mandatory for pylon competitions - and the models flew away at high speed. These pilots did do their training at home with XPS (iFS), without troubles. Only when they came to the competitions location the lockouts started. Oh, and no radio issues with the other 2.4er radios at all at the same spot.

This seems to be consistent with other reported crashes using XPS. I don't know if it is caused by the lack of hopping, voodoo spells, phase of the moon or a race condition in the firmware. But lockouts seems to happen occasionally, none in some locations while more in others.

And yes, I have also seen XPS (as IFS) perform well.

But I for myself prefer a radio that has a more consistent record of credibleness.

wrightme: sorry for your loss! Hope it can be repaired.
