Cowling for turbocharged Seawind as fitted at Devlin Aviation***
Devlin Aviation, located in Camas Washington, was developing
the modifications necessary to adapt turbo charging to the Seawind. Of course,
they were also engaged in building other Seawinds and other aircraft. This page contains a few photos of the shop and the people engaged in
building. Their turbocharger adaptation used the stock SNA engine mount. They
were actuating the dual turbo waste-gates with a geared electric motor (proven
At least one of the Seawinds Scott had been involved in building
is a non-quick-build kit. Among other things, he felt one of the most important
considerations is build sequence and recommended the following:
1 Set wing incidence
2 Attach aft spar fittings
3 Position landing gear as a function of 1 & 2
4 Flap drive position is a function of the aft spar fitting clearance and the
inboard flap hinge
5 Horizontal stab incidence is relative to wing incidence alone. That is the
critical dimension. Wing incidence is 3 deg relative to the fuselage but that
angle is not as critical as horizontal stabilizer to main wing.
Scott had developed a precise way to profile the airfoil.
Shown is the profiling fixture on the wing. For
additional information, see Scott's
posts in the ISPA hangar.
One of the tricky processes in building a Seawind is proper alignment
of the Main Landing Gear legs. They must fold into the fuselage and
wing without binding, and then must fold down in perfect alignment
so that the craft stays straight on the runway at 90+ MPH.
Scott's method was shown above.

All members of the Seawind community will be forever indebted to Scott's contributions and thought provoking discussions on our message board. His presence there is truly missed. Scott's ideas live on in many Seawinds as a number of members have adopted Scott's innovations to make their Seawind's much safer and more reliable. We will never know how many lives Scott's ideas may have saved.
Thank you Scott and we know that God has blessed us, by letting us know you.
