My Apogee Components, Inc Perigrine JR model rocket lovingly kit bashed into the DEVO WHIP IT! is now complete sans recovery system connection and spin testing. Without engine or parachute, weight comes in at 9.91 oz and stands 31” tall. With all the modifications entered into Open Rocket she shows a stable flight on an Aerotech Enerjet E30-4T with a stability of 1.14 without any additional nose weight. We’ll see how the spin testing goes to make a decision about the nose weight. You might recognize the Whip It! font from another 80’s Whip Master, Indiana Jones and Raider’s of the Lost Ark. The fins of this rocket have vinyl silhouettes of Indy as well in this homage to the two 80’s cultural phenomena. As with all my projects my beautiful bride Lorrena made all the vinyl graphics. Here’s a complete list of components for this really fun project: The base kit is the Apogee Components Perigrine JR. The energy dome nosecone and lower small energy domes were custom 3D printed items from GoopTroop on Etsy. The Bison Skulls were also 3D printed by ScaleGrail also on Etsy. The DEVO figure was from Super7.com. I also ordered the clear BT70 tube and BT70 Coupler from Apogee. The internal ceiling/floor bulkheads were made by me out of 2 layers of 1/8” balsa sheet. For the stage I added a 1/4” balsa riser. The stage lights are dollar store push pins and the DEVO name on the stage we’re just beads from a bead kit. I custom constructed the Boattail after replacing the engine mount with a longer piece of BT50 tube. I added another engine mount centering ring (made from Matt board for photos from Amazon) at the base to add more support for the rearward engine and the Boattail. I did not use the standard metal engine hook and instead bought an Estes 24mm screw on engine retainer also from Apogee. The nosecone to tube interface was a custom made double coupler made from the piece of BT70 tube not used from the kit. I replaced the shock cord from the kit for an engine mounted 250lb Kevlar shock cord. The Kevlar is by Emma Kites off Amazon. I’m using an automotive sandable primer and RustOleum stops rust gloss enamel colors. All graphics are being made from permanent vinyl cut on a Cricut cutter. The clear tube is a slightly different internal measurement from the BT so the couplers on both ends required quite a bit of modification to work. That about covers it. I think I whipped this project pretty good! #WhipIt #WhipItGood #DEVO #WeAreDevo #WhipMaster #markmothersbaugh #WhenaPoblemComesAlong #IndianaJones #geraldcasale #80sICONS #ApogeeComponents
