RE: WM Midget Mustang,which engine?
Iv'e had the plane for 8 years. Heres another issue. My original engine was a OS 91 fx. I installed two of them and they were junk which is why I went to the 1.08. Now with the 91fx and probably any other that is mounted sideways with a stock exhaust you will need an extension to get it below the cowl without rubbing the cowl. As with my 1.08 , the best thing is to use a pitts.
