Spektrum AR9210
Seems like a nice compact setup.

Would this suffice in my Flash or should I step it up to the AR 12200 for the added security of the fourth antenna?
Or should I stick with the original plan? Thanks!
I'll be going with a [link=http://powerbox-systems.com/e/powerbox_systeme/powerbox_sensor/start.php]Powerbox Sensor switch[/link] and a AR12020 in my UF.
Yebb, I'm spending channels like crazy because I can, lol.
I have two 33% Extras with AR 9210s. I have had one AR 9210 fail. Horizon replaced it. I also had the fun of helping Horizon/Spektrum figure out that the things are capable of 7.4 VDC and 6 VDC. The spec states 6 VDC, says nothing about 7.4 VDC andand I was seeing 7.4 volts.Horizon/Spektrum has the resulting procedure for toggling the voltage settings on the Horizon Hobby site in the bulletin on the product. I was pulling my hair out trying to figure that one out, when Dan Smith at Horizon/Spektrum took on the task and came back with the procedure for toggling the voltage. .
A few months ago, it appears that I somehow reset the Preset Failsafe to the Manufacturer's defaults when one of my AR 9210s lost the preset failsafe settings. Then, I was having trouble getting the presets to take w/o precisely timing the pressing of the bind button. I have telemetry on both planes. I asked Dan for the procedure to do a reset, which I did not get. Apparently since then they posted another procedure in the Manuals Section of the product on the web site on how to do a work-around on setting the Preset Failsafe with Telemetry. So Dan did work out the problem I was having. I just did not know about the resolution until I was browsing the site today.
So, ... At this point, I think we have worked out all the undocumented features and work-arounds except for the reset. If you can get past all that, the AR 9210s are excellent devices. I like them a lot. They handle the power you need, they have independent redundant supplies, and do not appear to be susceptible to any RF, etc. They are a bit pricy though.
The concept of 3 Rxers is good. Given what I know about antenna polarization, I can't imagine flying without three Rxers. Four may be overkill unless you have a lot of Carbon Fiber, etc. Did I mention that when the one AR 9210 failed, I still flew in the plane even though both trouble LEDs were lit and the rudder was twitchin' a bit? I guess that is what PowerSafe is all about. I suspect my next build will have another AR 9210 in it, unless I need more than 9 channels.
In contrast, you can with the cockpit SRS units.
Edited- sorry, I'm talking rubbish, it's the PB spectrum i was thinking off. It's a little clearer here.
