At Sun N Fun last year Mark Bierle of Earth Star aircraft had a new engine
that he was working on, on display. The engine called the Rad Cam is an 8
cylinder 2 cycle radial engine which weighs in at 50 lbs but puts out an
outstanding 60 horsepower.
Since last year Mark has just over 40 hours on the original engine in the R & D stages, and has had it installed on one of his Gull 2000 doing high speed taxiing and ground hops. At Sun N Fun 2003 he had unveiled his "production proto-type" which has undergone extensive changes, from his original design to allow him to meet his design goals. According to Mark the new engine may look similar but it has been totally redesigned, with the installation of a different cam, larger pistons and cylinders, and reed valve style of carburation, for better low end performance. With the new cylinders etc. he expects to be able to produce 60 hp at 2700 rpm, down from 3600 of the older engine configuration. Mark hopes to have the Rad Cam installed and running on one of his planes within the next month, with production engines available in about eight months. For more information contact: |
