Featuring a blend of narrow & wide frames, the Oxy 5 nitro offers a balance of both standard design cues, and feature focused on key components in important areas. Rigidity, strength, low weight, and aesthetics are aspects of the Oxy 5 nitro. After countless hours of design revisions and testing, Oxy Heli landed on the final design that met the critical design goals. Nitro requires high gear train efficiency, and high cooling capacity to squeak out every ounce of performance from the nitro engine. Low resistance gears, high output Lynx CNC Turbo Fan, and a efficient fan shroud to match aid in providing pilots with the best mechanical design concepts which translate to more performance. A sprag one way system ensures longevity and reliability, providing incredible strength for any type of flying style. The bearing block systems incorporates a sliding adjustment to eliminate main shaft play, which further reduces weight by eliminating main shaft collars. Lastly Fuel Tank access is critically important for all nitro pilots, and the Oxy 5 couldn't be any easier to access.
Built with an efficient single stage transmission, the Oxy 5 Nitro offers two gear ratios depending on blade selection for the pilot. Standard kit gearing offers 19T Pinion and 163 Mod 0.8 gears, which is suited for pilots looking for 600 - 625mm main rotor blades. If you're looking to shrink the model and run higher headspeeds, an optional 22T Pinion is offered and suggested for utilization of 550-575mm main rotor blades. Tail rotor drive features a 84T main pulley and a 19T tail pulley for a final drive ratio of 1:4.42. Depending on pilot choices you can increase this to 4.66 with a 18T pulley, or decrease this to 4.2 with a 20T tail pulley.
Through years of development across various helicopters, Oxy Heli understood that a solid rotor head system paired with a 10mm hollow main shaft, 8mm hollow spindle shaft, serrated center hub, and interchangeable dampening system was the only solution to pursue. A difficult problem to tackle on all 3D helis is the deviation error from zero degrees to full negative and positive collective. Oxy Heli tackled this problem with ease, and the Oxy 5 nitro offers a deviation of only 0.25 degrees with a 28 degree range of travel. Flybarless gyro adjustments will be minimal thanks to this excellent mechanical geometry offered. The rotor head offers pilots agility and precision in one single design.
Tail Rotor System
Tail performance is the single most important aspect of a pilot looking to progress and practice new maneuvers. A tail rotor system that doesn't feel "connected" is a concern for many, as in the event a blowout happens, a crash is mostly immanent and can happen in seconds. Oxy Heli understands this importance, and provide one of the highest efficiency tail rotor systems to date. Larger tail pulleys, low drag coefficients, and a simple design are all incorporated to the Oxy 5 nitros design. Mechanical concepts such as low belt wear, tail belt tension system, reduced mechanical travel error, double pinned pitch slider, and a 6mm tail output shaft are just a breif summary of the magic found within the Oxys' tail system.
