[NSRCA-discussion] Spektrum 2.4

Where is he flying from? I'm wondering that if there's a lot of
broadband use in that area then the signal clarity might suffer
(increasing latency). Did he note any change in latency between flights?
Odds are that the system selected two different frequencies each time it
was turned on.

Hello All ...
Jon, if anybody will catch the latency issue, it'll be your Dad.
He was one of the very few, along with Cliff Hiatt and myself that
griped loudly about the PCM-512 latency, those many years ago.
I eagerly await that your test-flying.
Trottle curves can be managed, even with an external box like the
7-point mix module that Webra intended for the computer carb.
Heck, we can even do a lot mechanically!
 
later,
Dean

	Curious, I was talking with a very good pilot and his opinion of
the spectrum was that it felt sluggish as compared to our current
radios, although hes flying the 14z.  He refered to it as having high
latency...
	 
	Can anyone comment on this?

		My Dad has one of the new DX7's flying in a 2 meter
Arresti III pattern bird and it works fine.  It is designed for all
uses, not just foamies.  I haven't flown it yet, but expect to over
Christmas.  One big deterrent for me is the fact that it doesn't have a
throttle curve in airplane mode.  I looked at using heli mode which does
have throttle curves, but there are only a couple of mixes available,
and neither includes trim.  Airplane mode has several programmable
mixes, a couple of them have trim available, but none have multipoint.
		 
		Since it is designed for all uses, there should be no
problem at the Nats, if you can live with the limitations.
