<P>Hi Jason,<BR><BR>The idle screw is leaned when turned clock-wise and vise-versa... Just like the main needle !<BR><BR>If the rpm accelerates as you describe I think your pipe length is too short making the engine peaky. Maybe the power will be a little lower with the longer pipe, but the running characteristics will probably be much better. There is more than enough power anyway!<BR><BR>When using the narrow and long Greve pipe set the length between 70 and 75 cm from the exhaust port to the first baffle plate. I use 73cm (uncut 3M header) on the new fatter Greve pipe on my Rhapsody.<BR><BR>Best regards,<BR>Morten Laugesen<BR><BR>e-mail: morten@laugesen.nu<BR>URL: http://www.morten.laugesen.nu<BR><BR>> Well, finally went flying today (without 40 mph winds) and tried the A5/F<BR>> combo. Still not super smooth transition. Leaned out the low end (I think,<BR>> counter clockwise) and transition was smoother on the ground, but still<BR>> loaded up in the air. I didn't go richer (clockwise?) cause of frustration<BR>> and sun burn, so that'll be tomorrow also. Am I doing this all wrong?<BR>> <BR>> Here's my real problem. I am flying basically an 11lb AS. No prop I've tried<BR>> from a 16x16-19x8 2B's to 15x13.5 &15.75x13 3B's and 15.25x12 4B can really<BR>> slow the plane down. The best seems to be the 15.75x13 3B and tomorrow I'll<BR>> try the 15x11 4B, but it seems that the motor is just winding up on the<BR>> downlines. Then it takes 1/2 the box to slow it down again so I can make a<BR>> smooth transition to full. This makes some of those rolling and snapping<BR>> passes a bit too fast. And forget the vertical maneuvers...they're horrible.<BR>> <BR>> Is it just because the plane is a pig or cause the 3M is a 2-cycle (or<BR>> operator error)?<BR>> <BR>> Thanks,<BR>> Jason<BR>> www.jasonshulman.com<BR>> <BR>> <BR>> =====================================<BR>> # To be removed from this list, send a message to <BR>> # discussion-request@nsrca.org<BR>> # and put leave discussion on the first line of the body.<BR>> #<BR>> <BR><BR></P>
