A problem facing many Rotax 912 engine owners, who are building their kits is finding someone to weld up an exhaust system for them from the parts supplied by Rotax. To alleviate this problem Otreb Technologies supplies the PUMA with a dual exhaust system, produced in North America by Toucan Exhaust Systems. This dual exhaust system comes ready to bolt on with no cutting or welding required. As an option the customer can also have the exhaust ceramic coated which will help dissipate heat better, gives the system a cleaner look, and longer life. Another unique feature of the PUMA is that it comes standard with an oil thermostat mounted to the engine mount. This aids in faster warm ups and keeps the engine at optimum operating temperature, which will really be appreciated by pilots flying in colder areas of the country. In the case of a thermostat failure, it is designed to fail in the OPEN position. The very efficient cooling system has three air inlets one in the lower cowl for the radiator and oil cooler, and two other inlets in the top of the cowl directly in front of the cylinder heads. The standard two blade wooden propeller supplied on the PUMA is being manufactured in Italy specifically for the PUMA. Optional two, and three blade composite propellers like the IVO, POWERFIN and WARP DRIVE are also available. Ground Handling, Suspension and Steering System
The PUMA features a tricycle gear landing system. The main landing gear structure is made from certified composite resin, molded under vacuum and cured at high temperature. With the castering nose wheel assembly made of 7075 aluminum. The PUMA has independently operated hand brakes, and wheels manufactured in the U.S. by MATCO. Turning at slow speeds requires a coordinated application of brakes and throttle. Once moving pilots are able to steer the PUMA by application of rudder and back pressure on the stick. |
