@LitterBug that model _doesn't_ have the full 4in1 multiprotocal module... I ordered that exact one and found out when it got to me.
it is as confusing as it gets because it uses the same verbiage in the description and the only place on the store page that I could find a difference is in the description "Internal CC2500 RF System(Frsky, Futabas SFHSS)" and a picture that says the same thing.
Those 2 items on a radio with an actual 4-in-1 shows 4 different chips on that line instead of the 1.
So, if it is your first radio and are good with the limited protocals, it looks like a good choice. However for someone like me who has a bunch of spectrum RXes and wants to be able to just use 1 TX... it didn't work for me.
from some conversations after I RMAed it, I found out that I might have been able to just purhase the 4in1 replacement part for the standard version of that and replace it myself to upgrade that one to a full 4in1.
[yes I had a bad time ordering that TX]
