Engines brand and it's based on their square stroke Speed B21 Ty Tessmann II edition engine.\u003c\/p\u003e\n\u003cp\u003eLike the M3X, the M3X V2.0 it’s been specifically designed for maximum power, performance and tune-ability. With this engine you will have a great and super smooth linear power from low to high R.P.M.\u003c\/p\u003e\n\u003cp\u003eThe carburetor, crankcase and crankshaft have been developed to improve fuel consumption.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCOOLING HEAD\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe cooling head has been redesigned by Modelix. It’s not as low as the B2102 lower profile but it’s lighter so it keeps the center of gravity as low as the B2102 but improving its performance on very high temperatures. It’s the same head as the M3T and M3S engines.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCARBURETOR\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike the previous M3X, the V2.0 comes with the 21 J3 carburetor. Its high-speed needle holder has been redesigned for a better refrigeration of the fuel flow into the carburetor, lowering the temp of the carb, and consequently it’s more stable with a great idle stability, improves fuel mileage and overall engine performance.\u003c\/p\u003e\n\u003cp\u003eBesides this, the uniball joint of the carb slide has also been modified with two stoppers instead of one. With this new modified design, you can easier adjust the angle of the uniball joint without having to disassemble the engine.\u003c\/p\u003e\n\u003cp\u003eThis carb offers a higher accuracy tuning, a very interesting advantage to experienced drivers.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBACKPLATE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe original design of the OS backplate has been modified. It’s been milled to improve the gas flow going to the piston.\u003c\/p\u003e\n\u003cp\u003eThe backplate is CNC machined and made of 7075-T6 Swiss Aluminum. The reason of making it with this material is to make it harder than the original and reduce the conrod-backplate friction increasing the life of the conrod and improving engine efficiency and performance.\u003c\/p\u003e\n\u003cp\u003eThanks to its design, you can remove the backplate without damaging the conrod even when it is on its lower position (PMI). The lateral grooves allow to easily remove the backplate without having to use any tool that can damage it.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCRANKSHAFT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe crankshaft selected for this V2.0 version is the B2101 one to increase the power at low RPM. This crankshaft has been designed by the O.S team of engineers to ensure an optimum flow of fuel thanks to the aerodynamic design and the silicone filling. It is balanced with a tungsten weight in order to increase the inertia to rotation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBEARINGS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn line with the high quality and performance of this engine, its two high precision made in Japan bearings ensure high idle stability, longer life and low friction at high temperatures.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVENTURIS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe engine is supplied with a 6.5mm aluminium venturi.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSLEEVE AND PISTON\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe sleeve with 3 inlet port and an exhaust port guarantee a low fuel consumption with a very high but smooth and linear power.\u003c\/p\u003e\n\u003cp\u003eBoth, the sleeve and piston are made from a high strength aluminium bar to improve its durability.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTECHNICAL SPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDisplacement: 3,49 cc\u003c\/p\u003e\n\u003cp\u003ePower Output: 2.61 hp @ 34,000 rpm     \u003c\/p\u003e\n\u003cp\u003ePractical Range RPM:  4,000 - 42,000 rpm\u003c\/p\u003e\n\u003cp\u003eBore x Stroke: 16,40x16,40mm\u003c\/p\u003e\n\u003cp\u003eSleeve: 3 + 1 ports\u003c\/p\u003e\n\u003cp\u003eRear Ball Bearing: steel\u003c\/p\u003e\n\u003cp\u003eFront Ball Bearing: steel\u003c\/p\u003e\n\u003cp\u003eCrankshaft: 14 mm\u003c\/p\u003e\n\u003cp\u003eCarburetor: 21 J3\u003c\/p\u003e\n\u003cp\u003eGlow plug: P3 Turbo\u003c\/p\u003e\n\u003cp\u003eExhaust Position: rear\u003c\/p\u003e\n\u003cp\u003eFuel type: 25% nitro.
