First off don't make the mistake I did and get the wrong "non-CMP" FW190. It is exactly the same plane except for the servo tray and fuel tank mounts. (There is no fuel tank placement on mine. Built my own.) The MOST IMPORTANT aspect of buying the wrong FW was of course the FOAM CORE WING. The CMP comes with a fully built up wing. Mine is a foam core with the spar and light sheeting. Don't get me wrong,,, it flys great. Most foam wing kits are killer flyers with tons of lift because of the light wing. BUT,,,,,,, retracts are a nightmare. I've built the rails and boxes twice now. I fly from pavement but once visited a friend's club in Oklahoma City where it was grass. I Never got off the ground before the gear broke out of the wing. Since then I've done some extensive research here on foam wings and hopefully have a stronger rail box. I used Sumo Glue "by Loctite". Like Gorrilla Glue it expands but stays plyable. Will give but not break like more brittle glues. My retracts are 704 series SpringAirs (74.deg) with custom 8" Robinaire struts. Lee's struts are not flimsy at all and weigh a bit more than Robarts, etc but will not bend. They do however add weight to an already weak rail box that has no place to attach to within the foam LE area of the wing like a fully built up wing has. Sorry to go on and on boring you but I thought the advice was warranted. Now for me,,, the rest of the plane is solid and works well. If someone could measure from the front to the back at the very middle of their (true built up CMP wing) basically the mounting area. Then I could determine if a true CMP wing would fit my FW and try to order one from Nitro Models, etc. "Please?"
