Ok dude knows his stuff. The pin switch is a Smart fly product and works with either their voltage regulators or power expanders. It should also work with a Spektrum power safe RX. What is pictured there is only the part that activates the solid state switch. What I see is a very well assembled airplane with top shelf components.

So the single line that is coming from the redundancy pin is not the only part for that setup? I guess what I am asking is that line coming from that pin, does that go directly into the receiver? Or is there something else that it plugs into which then runs to the receiver?

also, will the Spektrum AR8010T receiver work then with the current setup of the airplane?

The AR8010T does not have a built in soft switch. The AR12120 does. Not a big deal you can just use a different type of switch(s).
