hello Bax. I have an OS .55AX (new) and have a question or two.

here is some info: on a Aeroworks Edge 540T mounted at a 45 deg., using Morgan's cool power 10%, everything is stock with an MA 13X6 prop, and OS # plug.

1. I followed the break in process and have finished 10 flights and the motor seem to be losing power. I closed the needle valve until its leanest point and richen it up about a quarter turn. I have changed the plug with little change. Have any ideas?[sm=71_71.gif]. thanks in advance, V.
