Looking at the website, I seems the expander do not have any functionality to eliminate RF noise due to long leads.
Anybody know which one will do:
-provides full power to servos and clean power to receivers
-optically isolated
-Allow use of two batteries. Do not require separate battery for receiver.
[link=http://smservices.net/acatalog/Large_Model_Units.html]SM Services[/link] have one that's optically isolated, but requires a separate receiver battery. The also have an optical isolation unit only.
I guess only the powerbox does it all.. (?)
mmm, maybe you are not reading the same website I am -
The Smart-Fly Power Expander provides full power to servos and clean power to receivers at an affordable price..
In addition, the input power is regulated and filtered before it is delivered to the receiver. All signals in and out of the unit are RF filtered resulting in extremely clean operation.
The channels with four servos have each servo individually buffered for clean signals with long servo leads.
You can use two batterries with the SmartFly Batshare and feel safe. I use it in my 30% Edge with long leads to the tail servos with no problems. This has been a solid setup for me, and can't see why it wouldn't be just as good in a jet application. It does not have optical isolation, so susceptability to other noise generators is unknown.
