Overview
The first Hangar 9® Ultra Stick™ ARF revolutionized the Stick genre with innovative design twists that really spiced up performance such as a large, double beveled control surface for 3D flight, extra-large control surfaces and optional quad flaps. Building on the legacy of this popular design, the Ultra Stick 30cc ARF provides intermediate to expert pilots a giant-scale sport plane with a wide flight envelope. It features durable construction and an abundance of power options so you can make it as mild or wild as you want. As with its predecessors, the flaps and ailerons are double-beveled so you can take advantage of flaperon and crow mixes. These control surfaces, along with the rudder and elevator, have been oversized for even better 3D capability than before. Hardware and mounting options for gas and electric power are included. You can even add floats (sold separately). Enjoy an intoxicating blend of sport-flying fun with this superbly crafted ARF that more than lives up to its name.
Turnigy gas engines have evolved over the last few years, and have now culminated in the TP (Turnigy Power) series. These TP engines offer even more power and torque than previous versions, and they remain the perfect choice for model aircraft. They are lightweight, powerful, easy to operate, hand start with ease, and have a greater degree of reliability.
There is nothing like the look and sound of a twin-cylinder engine, the TP31-T is the perfect choice for a whole host of scale and sport model airplanes. The TP31-T has very easy starting characteristics and offers low maintenance running. It will give you almost as much power as its nitro equivalent but is more economical, and it uses regular gas that can be purchased from a gas station. The TP series comes with re-designed porting in both the head and cylinder which provides the extra power and torque. It still, however, allows the engine to be very easy to tune, whilst still maintaining a smooth power curve, and have a constant, reliable idle.
All TP engines have a composite insulator block that houses the reed valve and mounts between the Walbro carb and the engine. This insulator block helps stop heat transference from the engine to the carb for improved running. The supplied wide voltage TP electronic ignition module the timing automatically to give peak performance throughout the entire rev range of the engine.
The pumped Walbro carburetor sits underneath the engine which keeps the profile quite similar to that of a full-size flat aero engine, this makes it perfect for scale airplanes. Another feature designed to help fit the engine in scale cowls is the angled spark plugs, this reduces the overall width of the engine quite considerably. The engine includes stand-offs with mounting bolts, spark plugs, mufflers, and gaskets. Just add an ignition battery, a propeller, and mount it up to your favorite airplane.
