Back when I posted the pix of the Plantraco "Butterfly" I included in the picture a tiny DPDT relay with a coil rated at 5 volts. I breadboarded this and the receiver, driving the relay coil through a diode from one of the "steering " outputs. The combination worked OK, but since the RX was rated at only one cell, the motor that I had wired in didn't seem to be going fast enough to have any power. I noticed that in their ads they had a slightly larger board that they said was good for up to 12 volts and 3 amps- and I bought one of those. Got busy with other projects, and never tried the second board. Recently, going back to their website I see that they rate what looks like the same board at only 3.7 volts (1 cell) now.

You realize, I'm sure, that the Plantraco "actuators" work on a totally different system from normal R/C servos. I know just enough about electronics to make things sizzle, and to create spectacular smoke clouds, but I'm sure that one of these RX's could be run from a 2 or 3 cell pack through a 78XX voltage regulator chip (less than $1) and the steering output made to drive a couple transistors sending up to full pack voltage to a motor-- I just don't know what transistors to use.

Glad that you started another thread! No reason why all the R/C info has to be in one long one, and as you say, this will make finding specific info easier in the future
