3. Precious Metal | Unlimited Class P- 51 Reno Racer
;e highly modified Unlimited-Class P- 51 Mustang Racer known as “Precious Metal” (PM) is
represented here as it was flown at the Reno 2012. Prior to this, the airplane had straight-cut propeller
tips, a bare-metal fuselage, and smooth Day-Glo green wings. By the 2013 race season, PM had
several refinements made to it including a longer canopy, upgraded wing and stabilizer tips, and a
distinctive paint job. Anyone having built a kit (not an ARF) shouldn’t have too much trouble building it.
;e construction of the
model is typical balsa and
ply, with foam-core wings
being hot-wire cut using the
templates shown on the plans.
;e focal point of the Precious
Metal racer is, of course, the
contrarotating propeller setup
powering the model. A large
hatch allows easy access to the
radio and power system, and the
canopy is available from SIG Mfg.
