Unpacked the parachute boxes and reviewed contents/instructions. Put the rocket tube in and fished the washers/nuts down the channel to get them on the bolts. There is some conflicting information that I had to send a question in to factory on - the manuals say there is only one Rocket Tube Lifting Plate that goes on the bottom but the Sling/Evan videos clearly point out there are two for both top and bottom. I tend think there should be two as the angle of the rocket tube seems to point too closely to the parachute box wall if the second lifting plate is not included. Awaiting clarification from factory. Changed the support bracket for the pull cable and prepared it for routing through the fuselage. Added the needed rivnuts to the dash attachment bracket.
