Item Description Price Photos
SPEED-SLOPE WINDSHIELD Installation of this windshield results in lower cabin noise levels, dramatically enhanced appearance and improved visibility. Cruise speed is increased by 3-5 miles per hour. This windshield mounts approximately eight inches farther out on the nose than the original, and you will need to obtain a 1 foot by approximately 7 foot piece of glareshield cloth to install in front of and partially under your existing glareshield. We recommend a vertical card compass and the electronic OAT instrument of your choice be installed at the same time. Call with questions, or if your aircraft has a hot-plate installed. Windshields available in gray tint, green tint or clear. $1495

DORSAL FIN Adds stability and about 2-3 MPH to cruise. Enhances appearance and reduces VMC by approximately seven MPH. You will notice that after initial rudder trim is set, it will require almost no re-adjustment as fuel burns and weight shifts during flight. The fin is fiberglass, and is about three times the size of OEM. The fin is large enough to consider the option of installing hidden antennas and/or remounting an existing antenna inside. $1395

WING TIPS Adds lateral stability at low speeds and improves aileron control. Cruise speed increased by about 3-5 MPH. Enhances appearance and includes recessed navigation light mounts with streamlined lenses. Reduces wingspan by about 32 inches over stock tips. $2495
'E' MODEL NOSE KIT Another great enhancement to overall appearance, this modification adds about 14 inches to length compared to stock nose. Reduces noise levels and extends baggage compartment space. Looks identical to Aztec E & F nose. Includes streamlined landing-light lens and improved ventilation intake. This mod is highly recommended when using any nose-mounted slaved compass and is a must for any radar installation. We have noticed that slaved compass "swing" caused by electro-magnetic interference (landing light turned on) is minimized after nose installation. $5195
