No pistix needed.

You won't be able to switch fans without adding like a pico switch, and even then you'd have to use the trim adjusters to turn it on and off. Each stick has an up/down and left/right. You would obviously use the up/down on the left stick for forward/reverse, leaving the left right of the left stick open, which then could be used for a fan if you add a pico switch. The right stick would be used for left/right and the up/down is open for fan switching if you add a pico switch. As mentioned, you'd have to use the trim adjustment to then go extreme right or left to turn the pico switch on and off.(or extreme up and down depending on which stick you use. Really not very ideal.

As far as spring return, you're just going to have to open it up and see, your the first with that tx.
