Terry has it right. The RT-Mod suit is bigger (circumference of pieces) than the FX and FX-lite is the way to go if you want to source your own helmet since the FX is not accurate. The FX would fit you, but that's not to say that other makers would not. It's more about how you build it to fir you than what kit you buy. Most of the helmets out there are around the same size, AP, TE/2, ATA, and depending on your head size you may or may not be able to fit fans and all that in the helmet. Some people use welding shield for the lenses in their helmets and some use a sheet of green plastic which is movie-accurate. Some vendors will even sell completed helmets, most people buy a kit and assemble it themselves because assembled lids are expensive. I think Nomex flight gloves are the primary gloves used and Smitty sells those here, they can also be sourced from any military surplus place. Underarmour is popular for the body suit, though you can use a dance-suit, or off-brand stuff. For blasters you can get resin or rubber prop weapons, or buy a Hasbro E-11 and a conversion kit that has the resin parts needed to make the blaster look right. The gun pictured is for Sandtroopers, but the DLT (I think is the right name) can be carried by TKs. In terms of custom-fab, the kit is straightforward to assemble, and you can hang it off your person any way you like. There is a generally accepted way though which involves suspenders to support the ab/kidney plates as well as the shoulders and biceps. Troopermaster devised that setup I believe. The answers to all your questions can be answered in more depth by searching on specific topics, but don't hesitate to ask questions if you have them. Welcome to FISD.
