Hello, If you line the out let on your exhaust up to match the under hang angle of the engine a lot of the oil is thrown away from the plane. Please see my modification to Peter Millers cap21 from the August RCM&E. this installation starts easy by hand (which saves scuffing the spinner) and is very scale loking from most sides. The open underside is hardly noticeable in flight and the SC32 and plane bothe work great. Nice one Peter. http://
