The “Brown Arch” The Gateway to Aviation Leave Your Mark The design, symmetrical in nature, will consist of 3,000 tribute bricks, each measuring 2 feet by 2 feet. Within the design is a Biplane made up of 160 bricks – 120 bricks make up the wings, 20 reflect the struts, 6 complete the cockpit, and 16 bricks stand for the landing gear. Four “Compass Rose” bricks – two flanking the North and two flanking the South – will make up the “cowling” of the Biplane design. The center piece in the Compass Rose will be the official NOAA marker providing the distance to Kitty Hawk. Purchase your brick NOW and have it inscribed and placed by AirVenture 2010!

FIREWALL FORWARD
(strong, forged 78- and 82-mm cranks are popular) requires
machining work inside the cases, and many aftermarket cases
are supplied with the required machining already finished.
(Throws up to 92 mm are available from Revmaster and are
used with Revmaster’s proprietary cases, which feature relocated camshafts.) The most-popular “big VW” is 2180 cc,
achieved with a 92-mm bore and 82-mm stroke. (This is the
only engine size offered by AeroConversions.) It typically delivers about 80 hp, at 3400 rpm.
The biggest problem facing a builder is how to get a prop
hub on the crankshaft. All the established suppliers have solved
this problem, and the homebuilder should consider buying a
prepared case, crank, and hub, rather than experimenting with
re-engineering this critical assembly.
Dual ignition is typical, using a small spark plug that enters
the head at an angle. Both magneto/electronic and dual-electronic ignitions are available. The mag systems allow
hand-propping (the always fully advanced electronic ignition is
turned on after the engine starts) and adds a level of assurance,
in case of electrical-system failure. Most dual-electronic systems are powered by a single alternator. Revmaster has
dual-electronic ignition run from a dual-alternator system.
Great Plains and Hummel offer either magneto/electronic or
single-alternator dual-electronic, and AeroConversions has a
double-redundant dual-electronic system that ultimately runs
from a single alternator.

VWs present an inherently troublesome problem for intake
systems, since the inlets are on top of the heads. The result is an
overly long intake runner from the carburetor (below the
engine) to the intake ports. Separate runners for each port are
generally preferable to single runners that end in a common
manifold. The VW heads also are sometimes available with
“standard” or “large” valves. Bigger, in this case, is almost never
better; aero engines run at much lower rpm than auto engines
for which these big-valve heads were developed.
Speaking of heads, most of the cooling comes through the
heads and the oil. Proper baffling and good “engine tin,” avail-
able from all the suppliers, help; oil coolers (and remote spin-on
