I might cross-post it on TRF. Basically depends on if I feel like it tomorrow.
(note on abbreviations: LOC-Precision, here just 'LOC', is the company that makes the kit, including all the components. PNC = Plastic Nose Cone; BT = Body Tube)
Without further ado, what actually came in the bag:
- Nose cone: 3.5:1 plastic ogive PNC-2.56, color off-white. The shoulder is 2.5" long and includes a molded eye for shock cord attachment. It's standard-issue LOC thick-walled plastic - 112g (3.95 oz) accoridng to Apogee, and has raised ribs on the seams.
- Body tube: 30" of LOC BT-2.56; 2.56" internally and 2.63" externally weighing 139g (4.92 oz). The tube is thick-walled and high-quality, with an outer glassine wrap for strength and ease of finishing. The spirals are tight and shallow and will not interfere with finishing.
- Coupler: 3" of LOC 2.56" tube coupler; 2.479" internally and 2.555" externally weighing 11.8g (0.41 oz). It is also thick-walled and made of kraft paper; it is used to fit the 4 motor tubes into the rocket. Formerly Viper IV kits contained 2 plywood centerting rings, but those tended to snap durign sendign hence the change.
- Motor tubes: 4 lengths of LOC 24mm motor tube, each 12" long and in total weighing about 1 ounce. As well as the motor mounts, they are the entire aft end of the rocket.
- Fins: 4 plywood fins each 1/8" thick and total weight about 2 ounces. The root is 5" long, the tip 2", and they they're 4" wide. The plywood is incredibly high quality - very strong, and just 2 minutes with 120-grit sandpaper and steel wool makes each fin smooth on the faces and glass-like on the edges.
- Shock cord: 8 feet of 1/4" flat elastic for the shock cord plus a short length of nylon to mount it to the wall of the tube. Not incredibly strong, and below Madcow quality, but good enough.
- Parachute: 18" diameter circular black ripstop nylon parachute with 6 medium-length sewn-on nylon shroud lines. High quality and able to stand up to abuse; however, there is one tear in the edge sewing that is mostly merely cosmetic and takes 10 seconds with a sewing machine to fix.
- Launch lug: 6" of LOC 1/4" diameter launch lug. Decent quality.
To which I will likely add the following:
- Quick-link: simply to aid in changing the parachute.
- Motor retention: threaded rod between the motor mounts plus a few assorted nuts and washers. Will prevent the ejection charges from pushing the motors out instead of the parachute.
- Chute protector: 9" piece of aramid (Kevlar™) cloth that does not burn, to protect the parachute from the heat of the ejection charges. Will add with a quick-link to allow use on multiple rockets.
- Rail buttons: to allow launching off launch pads with launch rods or launch rails.
The total height is 9 + 30 + (12-3) = 48 inches tall. My second-tallest rocket after the Nike-Apache, my third cluster (after the Twofer and Multi-Goon), and my first 4-motor cluster.
Pictures, simulations, and actual building coming soon.
