This engine was produced with the electric start option only.</B></div> <div> <B>As a response to a wider range of requirements and well aware of the electric start over pull start debate among pilots, this year, JPX Italia released a new and light weight version of the Cors-Air engine with pull start. This was a bold step in a new direction.</B></div> <div> <B>Incorporating new designs,  the newest available technologies and craftsmanship, Mr. Oscar Meschiari, Chief Designer of JPX Italia went even further and produced an engine that weighs less than the Cors-Air M21Y (the electric start version)</B></div> <div> <B>A new engine was born: </B><FONT SIZE="3" COLOR="#FFFF00" FACE="Arial" ><B>The Cors-Air M25Y -Black Devil.</B></FONT></div> <div> <B>The Black Devil exhibits the same power, reliability, safety and low maintenance like its predecessor.</B></div> <div> <B> Just like the electric start version (Cors-Air M21Y) the Black Devil will have no broken muffles like  other brands of engines.</B></div> <div> <B>The slogan that JPX Italia uses for this engine is:</B><FONT SIZE="3" COLOR="#FF0033" FACE="Arial" ><B>" It's small like a 50 cc, it weighs like an 80 cc, but it pushes like a 200 cc engine and has the legendary reliability of the M21Y"</B></FONT></div> <bR> <div> <B> The total weight of engine and muffler is 31,9 Lb Lb, that  is  less than its predecessor (M21Y)</B></div> <bR> <div> <B>Last November, I had the opportunity to test fly the Black Devil during my visit at the Cors-Air factory in Cavriago (Italy) and I must admit that this engine surpassed my expectations. Smaller and lighter but as powerful as its predecessor, the engine runs incredibly smoothly and  it is very easy to start due to a hefty external vacuum operated automatic decompressor. The Black Devil has the same safety margin as the Cors-Air M21Y.</B></div> <bR> <div> <B>The Black Devil was presented at the </B><FONT SIZE="3" COLOR="#FFFF00" FACE="Arial" ><B>Parastar Convention (April 8-11 2004)</B></FONT><B> at Fantasy of Flight (Florida) and at </B><FONT SIZE="3" COLOR="#FFFF00" FACE="Arial" ><B>Sun and Fun (April 13-19 2004)</B></FONT><B> in Lakeland Florida.</B></div> <div> <B>Aerocorsair USA  presented the engine itself on its stand, next to Ohio Powered Paragliding where a new generation of AIRFER Paramotors with the Black Devil were also  presented.</B></div> <div> <B>The Black Devil was very well received by the community and many pilots had the opportunity to test fly it.</B></div> <bR> <div> <B>Mounted on a Titanium frame AIRFER Tornado paramotor with a 110 cm propeller and a weight of 54 Lb, the Black Devil pushed  a prompt 135 Lb of thrust. Mounted on an AIRFER Bimax with a 48 inch propeller, the Black Devil is a true tandem machine.</B></div> <div> <B>It has the best "power to weight" paramotor on the market so far.</B></div> <bR> <div> <B>Below, we publish a few pictures of the Black Devil and this page will be updated again very often.</B></div> <div> <B>In the pictures to come, we will present the Black Devil mounted on a paramotor, ready to fly. </B></div> <bR> <div> <B> </B><B>        </B></div> <div> <B>            <IMG SRC="7a2c2520.png" border=0 width="450" height="338" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>The Black Devil, just as the Cors-Air M21Y and like no other engine used in paramotoring has the cylinder tilted to one side.</B></div> <div> <B>This ensures that the engine is very hard to flood because the excess of fuel is easier expelled into the exhaust manifold. No other engine on the market has this feature.</B></div> <div> <B>Also, the tilted cylinder off-sets the weight distribution and partially eliminates the torque generated by the engine and propeller.</B></div> <bR> <div> <B>The Black Devil is easy to repair. There are no bearings pressed into the crankcase like on all other engines because the crankcase is split in half. </B></div> <bR> <div> <B>The Black Devil was designed to fit on virtually any existent frame on the market thus most paramotors can be retrofitted with this engine.</B></div> <bR> <div> <B>This makes the Black Devil a real universal engine.</B></div> <div> <B> </B></div> <bR> <div> <B>We offer two versions of this engine:</B></div> <div> <B>Hand start version (below)</B></div> <bR> <div> <B>          <IMG SRC="7a4b84a0.jpg" border=0 width="440" height="330" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>           <IMG SRC="7a6cc350.jpg" border=0 width="460" height="309" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>                                and electric start version as well:</B></div> <bR> <bR> <div> <B>      <IMG SRC="7a7cc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <bR> <div> <B>The cylinder head, piston and  cylinder are made are made of the highest quality materials, just like the Cors-Air M21Y (electric start version)</B></div> <bR> <div> <B>          <IMG SRC="7a9b84a0.jpg" border=0 width="440" height="330" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <div> <B>          <IMG SRC="7abb84a0.jpg" border=0 width="440" height="330" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>          <IMG SRC="7accc300.jpg" border=0 width="460" height="560" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>The electric starter has a factoty installed additional safety bracket.</B></div> <bR> <div> <B>    <IMG SRC="7aecc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>        <IMG SRC="7b0cc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>Compared to the older version (Cors-Air M21Y) the Cors-Air M25Y Black Devil engine in its electric start version has a miniature electronic ignition and battery chargins system.</B></div> <bR> <div> <B>          <IMG SRC="7b2cc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>The heavy fllywheel used on the M21Y engine was replaced with a miniature one and it is very well balanced.
