I do believe your limited to the manual electric trim option on the 50, about $3K on hardware and whatever the dealer wants to install it. Having just put a System 30 in my 185, the pitch servo is just a joy to install, as it is back in the tailcone. The Trim option for a 182 would install back there as well. So it is a combination of running the harness from tail to panel, putting in the switches and wires to your yoke, and mounting the brackets and bridals to attach to your trim system. So bottom line, a lot of interior has to come out, some metalwork on the tailcone, and some mods to your yokes. Nice thing about STEC, they come with pre-built harness & brackets from the factory and a comprehensive hardware kit. The documentation is a bit of a head scratcher at points. However, they build to order, so expect some delay. They only sell to dealers to do the install.
