	12986 : OS.32SXH Engine (RINGED) Developed for small helicopters, the O.S. MAX-32SX-H is an all-new engine, not a modified version of its predecessor, the 32F-H. With many of the design features of the larger, F3C competition standard 61SX-H, the high performance 32SX-H has a new design of large bore carburettor - type 20C - to provide stable hovering characteristics and more power at the top end. It also includes a plated crankshaft to prevent corrosion and to increase the engine’s durability, a new rear ball bearing design with specially heat treated balls, enlarged con-rod and crank pin and a heat treated piston pin. With its twin ball raced crankshaft, enlarged cylinder head for improved cooling and identical mounting holes and crankshaft thread to the earlier 32F-H, the 32SX-H makes a worthwhile upgrade for any flyer. Price: £85.10 £99.99 Including VAT at 17.5%


	12987 : OS.32SX-HX Recoil Start Helicopter Engine Although basically identical to the standard 32SX-H Ring, the 32SX-HX is equipped with a handy and durable pull-start system. No more lugging about of heavy 12V batteries and starters with this engine. All you need is fuel and a glowstart and you're ready to fly. The 32SX-HX will not fit in some helicopters but ideal for the Hirobo Shuttle or similar Price: £130.20 £152.99 Including VAT at 17.5%


	14000 : OS.37SZ-H Engine (NEW LOWER PRICE) The all-new 37SZ-H engine is fully compatible both with regard to mounting hole and muffler position to the popular O.S.32SX-H and can therefore be mounted in any of the existing 30 class helicopters. To achieve the low vibration required for a helicopter engine, a good balance has been struck between both the higher r.p.m. for aerobatics and lower r.p.m. for stable hovering which results in smooth power across the entire r.p.m. range. Thanks to a specially designed 20M carburetor, this power can be obtained right from idle, through hovering or during stunning 3-D flights. The 37SZ-H almost exceeds the limits of a 30 class helicopter. Price: £85.10 £99.99 Including VAT at 17.5%


	15550 : OS.50SX-H Ringed Hyper Engine (New Lower Price!) The 50SX-H combines balance with usability in any 50 class helicopter. This popular engine is now offered with even more power. The cooling efficiency has been improved using a new blue anodized heat sink head. The new head design offers greatly improved combustion efficiency which delivers stable power for hovering and aerobatic flight. The specially designed carburettor has a large, 10mm diameter intake which gives the engine even more stability. The "MAX-50SX-H RING Hyper" brings even higher performance to the many modelers flying in this class. Price: £100.42 £117.99 Including VAT at 17.5%
