Just ordered Robart Retracts for my SBD a couple days ago and I'm studying the plans to get my ducks in a row for installation. This is my first retract job and the plans are designed for mechanical/servo gear so I need some help with what may seem obvious to most of you...

The SBD has a one-piece wing and I'm assuming that I'd want my air system & cylinder all to be in the wing??? I don't think that you'd want to connect & disconnect air lines between the fuse and wing every time you flew... seems like potential for wear & leaking. Likewise for fill valves, pressure checks, etc.

I think that my system comes with the Medium size air cylinder, which is 8" long by 2-1/4" diameter. This size will require a good bit of cutout in my 85" wing, which concerns me from a structural strenght standpoint.

Any advice??

Thanks!
