They utilize a patent pending high-strength polymer case and bulkhead, ceramic nozzle and RCSs exclusive Black Max™ aerospace- grade composite propellant formulation, which produces nearly double the specific impulse (or \"Isp\", a propellant efficiency rating) of conventional black powder propellant. They are not susceptible to thermal cycling like black powder motors. Q-Jets generate a highly-visible exhaust plume and delay smoke trail. All Q-Jets ship with a FirstFire Micro™ 2-lead initiator, which can be used with any launch controller.\u003c\/p\u003e\n\u003cp\u003eSPECIFICATIONS:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMotor Diameter: 0.698\" (18mm)\u003c\/li\u003e\n\u003cli\u003eCasing Length: 2.75\" (70mm)\u003c\/li\u003e\n\u003cli\u003eTotal Impulse: 9.8 N-sec\u003c\/li\u003e\n\u003cli\u003eBurn Time: 0.84 seconds\u003c\/li\u003e\n\u003cli\u003eAverage Thrust: 12 newtons\u003c\/li\u003e\n\u003cli\u003eDelay Time: 8 seconds\u003c\/li\u003e\n\u003cli\u003ePropellant Weight: 7.7 grams\u003c\/li\u003e\n\u003cli\u003eMotor Weight: 23.7 grams\u003c\/li\u003e\n\u003cli\u003eMaximum Liftoff Weight: 56 grams\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Quest Aerotech","offers":[{"title":"Default Title","offer_id":41363827425446,"sku":"QUS6118","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0520\/1972\/4454\/products\/aerotech-6118-q-jet-black-max-composite-model-rocket-motor-c12-8fj-2-pack-ships-usps-ground.jpg?v=1632771508","url":"https:\/\/www.whiterosehobbies.com\/products\/aerotech-6118-q-jet-black-max-composite-model-rocket-motor-c12-8fj-2-pack-ships-usps-ground","provider":"White Rose Hobbies","version":"1.0","type":"link"}
