Hey guys Im about to begin work on a Top Flite Sea Fury and had some concerns about retracts. I was going to go with the easy route and get the century jet 3/8 system comes with everything made for the sea fury but after reading around and seeing so many people bash on ho CJ is crap and brakes easy im kinda scared to go that route. Now Im looking into the Robart 510 series with 7/16 robostruts (if that would work?) but I like for the speed of up and down motion to be controled because i love scale looks witch is why I was concerned because the 510 retracts are sprind down. I could see how the the speed could be controled up because there air up but wasnt sure about down because spring? Either choice I made would be from Tower because as a member you seem to get some awsome deals through them. Any help would be great, thanks
