My brother David Adamisin passed away Sunday. He was a very good Stunt flyer but was more interested in engine work. He started helping Dad work on engines while still a teenager. Appropriately, spent most of his professional career working at Ford in the Advanced Engine Lab. Among other things, he patented a five-valve design that was used in Formula one racing engines. He did a lot of work in intake an exhaust system design modeling, and as a result was a pioneer in various rapid prototyping methodologies.
If you are or have flown a stunt engine with the boost port blocked then you are benefitting from a concept pioneered by Dave. When the OS-FP series replaced their easy to run S-35s, they introduced Schnuerle porting to sport engines but did not make much useful power. Dave tapped into his experience with port design at Ford to determine that the engines needed to run over 20k to get any meaningful flow velocity through the intake ports! Blocking the middle port greatly enhanced the flow velocity and air-fuel mixing so the engines could drive useful props.
Dave worked with Pete Bergstrom at Horizon to develop a special CL Stunt version of the Evolution 36. Later, he alerted Pete to the possibility of building a 60 into the Evolution 40/45/46/52 block. The resulting Evolution 60 quickly earned a reputation for good power and easy to handling. Dave & Pete prototyped an Evolution 40 built in the 36 case that runs extremely well sadly the CL version never made it to market.
In recent years Dave got into 3D printing then got into it in a huge way. If you are using a 3D printed mount from Tom Morris or Russel Honea, you are using one of Daves pieces. I introduced Dave to Tom Morris, and the two of them collaborated on designing and refining the printed mounts that Tom uses in his ARFs. Later that business transferred to Russel Honea at Okie Air. Dave has made over 500 mounts. He had also worked on a TON of experimental mounts, like the ones I am using to convert airplanes with beam mounts to accept beam-mounted outrunners
Dave had been building and re-building a lot of airplanes and was really excited at the prospects of trying everything out this summer! Ironically, one of the last projects Dave worked on was to 3D print a bypass blocker for a Fox 35. Yep, no need to whittle a piece of pine to do the job!
Aside from his aero modeling efforts, Dave rode dirt bikes, play golf, coached his kids in baseball & Softball, and generally provided a role model of an active involved and loving family man.
Visitation will be Sunday, February 13 at:
