RE: Pica/Platt FW-190D9 Build Log
I have Robart retracts in mine. They are the spring down variety, and have worked very well. I had to lengthen the Robostrut though. I JB welded thick (1/4") I think, inside the strut and then sleeve it with brass tubing. This has worked well also. Not sure if Robart has a strut long enough. At least with Robart, you can get it quick from Tower hobbies.
