He has flown PG for 12 years and PPG for 4 years. Mike has built 6 home made paramotors and he is now working on a PPG trike soon to be released. He is one of the Australian importers and distributors of the well known  Cors-Air M21Y engine based AIRFER Tornado and Bimax Paramotors  from Spain.</B><FONT SIZE="2" COLOR="#00FF00" FACE="Arial" > </FONT></div> <div>                                                                                                     </div> <div>   <B>Alex Varv</B></div> <bR> <div> <B>Because I enjoy very long flights on my machine, I built an auxiliary twin integrated fuel tank system that allows me to enjoy much longer flights. This system is easy to build, safe and if one is ready to lift more pounds to achieve  a longer flight here is how to achieve this goal:</B></div> <div> <B>The two auxiliary tanks are fastened in a very safe way to the cage by means of a stainless steel brackets.</B></div> <div> <B>First, to make the brackets we need  to find some tanks that have a good shape and fit the cage area. </B></div> <div> <B>The brackets are made from S/steel 6mm rod and S/steel pipe cut in half to make a good section that will fit your cage in a position that is stable and strong. </B></div> <div> <B>On the AIRFER Tornado it fits great but the system could be made to easily fit most paramotors. </B></div> <div> <B> In the picture of the single tank with the couplings we will show that the two rods are basically two parallel pieces and are connected at a half piece of pipe top and bottom that sits against the cage in a convenient spot. On the AIRFER Tornado you can see that it has a great location that is stable and strong.</B></div> <bR> <div> <B>                                                                                                                         <IMG SRC="221cc330.jpg" border=0 width="460" height="307" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>                                 I bent a locating spot for the bottom spring that you can see which holds the tank and also you can see the rubber tube that protects the tank from wear because of vibration.</B></div> <bR> <div> <B>                                                                                                                                                        <IMG SRC="223e1520.jpg" border=0 width="225" height="338" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <div> <B> </B></div> <div> <B>The spring at the top holds the top of the rods firm against the tank so it can not come out the top of the bracket.  The springs have clear tube over them as well . The two half pipe connections per bracket have ONE WRAP velcro pop riveted to them and this simply raps around the tube of the Tornado frame. ONE  WRAP velcro simply sticks to it self and is fantastic stuff.  There is some stick on rubber tap stuck to the contact side of the pipe to give a cushion effect [this is hard to see in all the pics]. </B></div> <div> <B>The picture of the two tanks connected together shows the pipe locations . The pickup tubes of the two tanks are connected together with a brass Tee and have a female coupling .  The breathers are connected the same way  with a male coupling.</B></div> <bR> <bR> <div> <B>                                                                                                                  <IMG SRC="224cc330.jpg" border=0 width="460" height="307" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>This is important and should be set up this way .  On your motor simply cut your breather in a good spot and put the same couplings in the breather line in the correct portion .  This would be the smaller male coupling on the breather from the tank and the female larger coupling on the existing breather. This means that you can connect the main tank breather nipple to the two pickups from the reserve tank ,I have made a small change that does not show up in the picture of the couplings and that is the joiner Tee is now in the middle of the fuel line between each tank or you get more suction from the closer tank if they are of set as shown,and the tank that is further from the Tee will still have half a liter or so left when the other tank is empty. </B></div> <bR> <div> <B>                                                                                                                 <IMG SRC="225cc330.jpg" border=0 width="460" height="307" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>This system works based on the following: as fuel is drawn from the main tank ,which needs to be full to get best suction, it has no breather on it but now has been connected to the reserve tank pickups. What this means is that it sucks fuel from these tanks at the same rate that it is being sucked from the main tank. The two reserves have breathers and allow the air in as the fuel is sucked out of them. </B></div> <div> <B>The fuel simply drains into the main tank and is used by the motor.  When you take the Reserve tanks off, you simple plug the couplings on the motor together reconnecting the normal breather and plug the reserve couplings together, breather and pickup and no fuel can leak!  By using this system the fuel tanks can not fail like in some other setups I have seen.</B></div> <div> <B> </B></div> <div> <B>                                                                                                                   <IMG SRC="227cc300.jpg" border=0 width="460" height="304" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <div> <B>You also can remove and replace tanks as required by simply adding another set of couplings between the two reserve tanks so you can add one reserve or two and have it set up like the pics . </B></div> <div> <B>The famous tank mirror may need to be positioned in a new spot as you still need to see the main tank once the reserves have emptied. </B></div> <div> <B>Total cost was about $100.00 Australian dollars. </B></div> <bR> <div> <B>For more info, please feel free to contact me at your convenience at:</B><B> </B><FONT SIZE="2" COLOR="#00FF00" FACE="Arial" ><B>     </B><A HREF="mailto:info@forwoodflightandfun.com" TARGET="_top" TITLE="mailto:info@forwoodflightandfun.com"><U><B>info@forwoodflightandfun.com</B></U></A></FONT></div> <div> <B> </B></div> <div> <B> </B><FONT SIZE="2" COLOR="#00FFFF" FACE="Arial" ><B>Fly safely,</B></FONT></div> <div> <B> Mike Forwood </B></div> <div> <A HREF="http://www.forwoodflightandfun.com" TARGET="_top" TITLE="http://www.forwoodflightandfun.com"><U><B><U>www.forwoodflightandfun.com</U></B></U></A><FONT SIZE="3" COLOR="#000000" FACE="Arial" ><A HREF="http://www.forwoodflightandfun.com" TARGET="_top" TITLE="http://www.forwoodflightandfun.com"><U> </U></A></FONT></div> <bR> <bR> <div> <B>             </B><A HREF="index.html" TARGET="_top" TITLE=" "><U><B>Back to Inventions</B></U></A><B> </B><FONT SIZE="3" COLOR="#000000" FACE="Arial" >       </FONT></div> <bR> <div>            </div> <bR> <bR> </td> </tr></table></body>
