    Polini Motori is glad topresent the new Polini THOR 200EVO, which means never ending technical evolution for PoliniMotori. The THOR 200 EVO engine has many improvements thanks to the newfollowing features:
    • New transfers and exhaust diagrams
    • New head drawing with embedding in the cylinder
    • New crankshaft with filling inserts
    • New cooling shroud And a modification for the Walbro carburetor

    All these mechanics improvements concretize in advanced technology, betterperformance, and extraordinary weight/power ratio and above it is possible toexploit all the engine power.
    The cooling is better after a careful inspection of the air flows for theengine cooling and thanks to the new cooling shroud which keeps the operatingtemperatures under 10-15% (in standard conditions) increasing the enginereliability.

    The most important development refers to the carburation. Polini has been ableto develop both the models together, one equipped with bowl carburetor and onewith Walbro carburetor. And during this stage it has been clear that to finishthe job it was necessary to follow two different ways:
    - Thanks to the upgrade the models with bowl carb proved to be reallyperforming with a constant power output at all rpm, contained temperatures andreduced consumptions. Furthermore it features a torque increase and a widerengine range. Now the engine reaches 8000-8200 rpm. It is recommended the useof a propeller with more pitch to better exploit the engine trust that the newThor 200 EVO offers.
    - To find the best Wabro carburetor setting the opening of the throttle valvehas been limited: this allowed a torque increase and a smoother power output.The maximum engine range is 7400-7500 rpm and it is reached faster than withthe previous Thor 200 model. It is not necessary to use a different propeller.

    TECHNICALFEATURES

    CARBURETORS
    The new THOR 200 EVO is an advanced engine that can use two different fuelsystems: d.28 PWK model carburetor or WB37 WALBRO carburetor.

    CENTRIFUGAL CLUTCH
    The centrifugal clutch has been studied to grant the best safety featuresduring all the stages: starting, take off, flight and landing.

    BALANCING COUNTERSHAFT
    It is equipped with a balancing countershaft which cancels any vibrationgranting more comfort and longer last of the engine when flying.

    EASY STARTER
    THOR 200 EVO engine is provided with the new Polini “Flash Starter”, reallyeasy to start. A version with electric starter is also available.

    SPECIFIC POWER UNIT
    The cylinder is cast in light alloy and its liner has a nickel-chromecoating for the best piston sliding. The piston is gravity die-cast in lightalloy at high silicon content with 2 special chromed and nitride steel rings.The design of the piston top optimizes the compression ratio.

    CRANKSHAFT
    Crankshaft with filling inserts to increase the primary compression ratio andgrant a better mixture flow.

    EXHAUST SYSTEM
    The exhaust system is completely hand made for a better product quality.Compact design and contained dimensions. The reduced overall dimensions improvethe aerodynamic and grant a low noise level.

    FRAME CONNECTIONS
    The frame-engine connecting points of the Polini Thor 200 EVO are exactly thesame as the other engines: Thor 130, Thor 190, 200 and 250.

    ADVANCED SOLUTIONS
    Polini THOR 200 EVO engine features many other technical solutions and safetycharacteristics. System with closed circuit for the fuel collection during itstransportation (only for models equipped with PWK model carburetor)Prearrangement for 12V exit for future electric devices. Very low propelleroverturning torque granted by the counterturning masses.

    WEIGHT AND DIMENSIONS
    It is important to underline that all these improvements haven’t compromisedthe weight and the overall dimensions which remain exactly the same as theprevious model.

    DEVELOPMENT
    It has been developed and produced following all the criteria for the handcraftproducts with the most modern and advanced production methods and under thesupervision of highly specialized technicians who have achieved greatexperience, skill and creativity during the years.
