Default Re: Kiwi's XPS test results are up.

DSM2, not yet. But I did test DX6 + AR6000 combo and it was considerably more robust.
Many people related problems with the AR6100, but the AR6000 with its two
receivers always seems to relink within 2 seconds when going from full loss of link
back to being able to see its signal. I don't know if the pilot who's DX7/6100 system
I tested has sent anything back to Horizon yet, but there were so many people relating
"normal" poor performance for the 6100 that I generally wouldn't trust em.

One theory tossed around with respect to the AR6100 is that since it only has one
receiver, it's only listening on one of Spektrum's two channels (some theorize
that it rapidly switches back and forth between them, but I don't think there's any
evidence to support that). My suspicion is that all the dual receiver Spektrum systems
are able to continue to listen to the original channel, even while they're
scanning for the Tx on its new channel, which accounts for the faster re-link,
while the AR6100 on its one channel (or one receiver), can either listen or scan, but not both
and it's more easily blocked, which of course is a major
criticism of XPS. The difference between the AR6100 and XPS though, is that XPS will
hot-link instantly once the signal is visible again, while the AR6100 may lock you out for
5-15 seconds while it rescans.

[edit] More info on this since last night.
Here's a quote of a post on RCG in my thread regarding this issue
