Product Review Four Pi OT-40
ThE OT-40 is the modeling equivalent of what we called a
“sleeper” in the bad, old days of street racing: a four-door Chevy
Nova with a zillion-horsepower engine. The OT-40 looks like an
Old-Timer. It resembles many pre-World War I airplanes with an
open rear fuselage; exposed pilot; and shoulder-mounted, high-lift
wing.
You would expect the OT-40 to be great at flying low, slow,
large circles and not much else. Wrong! It does have great slowflight
behavior, lands at approximately 5 knots, and is forgiving, but
it climbs like a rocket, rolls fast, does outside maneuvers and
inverted flight as well as it flies upright, and will outrun most sport
airplanes. The secret is a fairly thick symmetrical wing with the
center of lift placed well forward and a blunt leading edge (LE)
paired with a sophisticated design combining strength and low
weight.
