Diezel 0 #1 October 6, 2015 Is it OK to use Aerodyne 21 inch risers on Mirage G4, the white loop being quite a bit longer then standard Mirage loop. I myself don't see any problems, but what do I know... Quote Share this post Link to post Share on other sites
riggerrob 558 #2 October 6, 2015 Fortunately, (3-Ring Inc) published common standards for 3-Ring riser manufacture a long time ago. Since 1998 most of the manufacturers have been sewing risers to the same standard, so they are cross-compatible with most harnesses. The longer white loop just improves the mechanical advantage of the Aerodyne risers .... a good thing because it reduces pull-forces on the handle. Is the RSL ring on the correct side to make it compatible with your Mirage? Speaking of compatibility, do the Aerodyne risers have round rings .... or oval "Mini-Force" rings? Mini-Force risers require slightly longer release (3-Ring) housings that might not be compatible with your harness. Fortunately, most other harnesses have enough slack (excess length) release housings to accommodate Mini-Force risers. When in doubt, ask your local rigger to inspect before you jump it.

Diezel 0 #3 October 6, 2015 Makes sense, thanks Riggerrob! They are 'mini-force' rings but looks like 3 ring housings on my mirage are large enough to accommodate them. I'll show it to some one before jumping though. Thanks again! Quote Share this post Link to post Share on other sites
riggerrob 558 #4 October 6, 2015 The next step in the compatibility-check is to attach your new(Aerodyne) risers to your (Mirage) harness. Wrap one hand around the harness (just below the 3-Ring) and pull the riser in a variety of directions. If you always have a bit of slack in the (metal) release housing .... Cool! Finish assembling your rig and go jump it! OTOH if you see any tension on the (metal) release housing, your new risers are incompatible with your harness.

riggerrob 558 #5 October 7, 2015 The most critical dimension is the distance between the bottom edge of the harness ring (e.g. RW-8) and the grommet through the riser. The worst combination is installing long risers (e.g. Aerodyne Mini-Force) on a short (RW-8) harness ring. OTOH Quote Share this post Link to post Share on other sites
