O.S. glow plugs have been used repeatedly as a trusted brand by modelers around the world.  Among others, the ever popular No.8 has been known as the industry standard plug by 2-stroke engine users. Now about to be released, the all-new OS No.7 plug lies in the medium range, slightly hotter than No.8. Every aspect of the No.7 plug including the coil is newly designed and developed. It covers wide range of engines and with rich mixture, offers stable idling, broad peak needle and punchy acceleration. This next generation glow plug has been developed focusing on easier handling at low and medium speed range than No.8.  The No.7 suits most 2-stroke airplane, helicopter and car (expect turbo heads) engines. No.7 is especially recommended for helicopter engines because it offers superior performance around hovering r.p.m. range which is critical for smooth and powerful 3D and F3C type flight.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\" colspan=\"2\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable cellpadding=\"0\" cellspacing=\"2\" border=\"0\" width=\"610\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"OS Engines","offers":[{"title":"Default Title","offer_id":14995501219875,"sku":"OSM71607100","price":15.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0036\/2115\/8947\/products\/os-no-7-medium-hot-glow-plug-1167712080.jpg?v=1751163723"},{"product_id":"os-engines-standoff-5x44-5mm-1-3-4-4-gt33","title":"OS Engines Standoff 5x44.5mm 1-3\/4 (4), GT33","description":"\u003cp\u003e\u003cstrong\u003eO.S.

The 10G carburetor has a remote needle valve mounted on the engine back plate which makes tuning easier and safer. Added webbing on the crankcase strengthens high-stress areas to help ensure that they stand up to the rigors of learning to fly. Includes #871 muffler and #A3 glow plug. Fuel for this engine is recommended to use 5~20% nitro, with at least 18% oil content.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdl\u003e\n\u003cdt\u003eDisplacement\u003c\/dt\u003e\n\u003cdd\u003e0.15 cu in (2.5 cc)\u003c\/dd\u003e\n\u003cdt\u003eBore\u003c\/dt\u003e\n\u003cdd\u003e0.598 in (15.2 mm)\u003c\/dd\u003e\n\u003cdt\u003eStroke\u003c\/dt\u003e\n\u003cdd\u003e0.539 in (13.7 mm)\u003c\/dd\u003e\n\u003cdt\u003ePractical rpm\u003c\/dt\u003e\n\u003cdd\u003e2,500-18,000\u003c\/dd\u003e\n\u003cdt\u003eOutput\u003c\/dt\u003e\n\u003cdd\u003e0.40 hp @ 17,000 rpm\u003c\/dd\u003e\n\u003cdt\u003eWeight\u003c\/dt\u003e\n\u003cdd\u003e4.87 oz (138 g)\u003c\/dd\u003e\n\u003cdt\u003eRecommended Props\u003c\/dt\u003e\n\u003cdd\u003e7x4, 7x5, 8x4, 8x5\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"OS Engines","offers":[{"title":"Default Title","offer_id":43588684611619,"sku":"OSM11536","price":179.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0036\/2115\/8947\/files\/os-engines-max-15la-s-15-nitro-aircraft-engine-with-871-silencer-11536-1253182775.webp?v=1786001020"},{"product_id":"os-engines-muffler-mounting-screws-873-2pcs-46ax-55ax-25425400","title":"OS Engines Muffler Mounting Screws 873, 2pcs, 46AX, 55AX [25425400]","description":"\u003cp\u003eThis is the OS Engines Muffler Mounting Screws 873, 2pcs, 46AX, 55AX [25425400]\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOS Engines Silencer Fixing Screw E3020.873(Csm3x35)\u003c\/span\u003e\u003c\/p\u003e","brand":"OS Engines","offers":[{"title":"Default Title","offer_id":43588688379939,"sku":"OSM25425400","price":8.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0036\/2115\/8947\/files\/os-engines-muffler-mounting-screws-873-2pcs-46ax-55ax-25425400-1253182779.webp?v=1786000973"},{"product_id":"os-engines-front-bearing-46ax-55ax-ggt15-gt15-26731002","title":"OS Engines Front Bearing, 46AX, 55AX, GGT15, GT15 [26731002]","description":"\u003cp\u003eThis is the OS Engines Front Bearing, 46AX, 55AX, GGT15, GT15 [26731002]\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOS Engines Ball Bearing (F) 40-61.70s.91s\u003c\/span\u003e\u003c\/p\u003e","brand":"OS Engines","offers":[{"title":"Default Title","offer_id":43588689625123,"sku":"OSM26731002","price":21.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0036\/2115\/8947\/files\/os-engines-front-bearing-46ax-55ax-ggt15-gt15-26731002-1253182780.webp?v=1786000961"},{"product_id":"os-engines-cylinder-liner-gt33-28303100","title":"OS Engines Cylinder Liner, GT33 [28303100]","description":"\u003cp\u003eThis is the OS Engines Cylinder Liner, GT33 [28303100]\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOS Engines Cylinder Liner Gt33\u003c\/span\u003e\u003c\/p\u003e","brand":"OS Engines","offers":[{"title":"Default Title","offer_id":43588697849891,"sku":"OSM28303100","price":96.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0036\/2115\/8947\/files\/os-engines-cylinder-liner-gt33-28303100-1253182781.webp?v=1786000951"},{"product_id":"os-engines-piston-pin-retainer-gt33-gf30-v1-gf30-ii-28317000","title":"OS Engines Piston Pin Retainer, GT33, GF30 V1, GF30 II [28317000]","description":"\u003cp\u003eThis is the OS Engines Piston Pin Retainer, GT33, GF30 V1, GF30 II [28317000]\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOS Engines Piston Pin Retainer Gt33\u003c\/span\u003e\u003c\/p\u003e","brand":"OS Engines","offers":[{"title":"Default Title","offer_id":43588699160611,"sku":"OSM28317000","price":10.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0036\/2115\/8947\/files\/os-engines-piston-pin-retainer-gt33-gf30-v1-gf30-ii-28317000-1253182782.webp?v=1786000939"},{"product_id":"os-engines-gf30-ii-four-stroke-engine-with-f-6040-silencer","title":"OS Engines GF30 II Four Stroke Engine with F-6040 Silencer","description":"\u003cp\u003eThis is the OS Engines GF30 II Four Stroke Engine with F-6040 Silencer\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe GF30 II is THE power plant for models designed for 120-150 glow engines or 20cc gas engines.
