Oxy Heli's Oxy 4 will astound pilots of all skill level with extreme quality, precision, design, and flight characteristics like no other 450 class helicopter has previously. After 2 years of testing with thousands of test flights and many updates through out the time line, Oxy 4 will simply be the epitome of design for years to come.
This latest "sport" iteration is a simple update at the Oxy factory by removing the previously included CF Rotor Blades in the kit, lowering kit cost. A secondary update includes the out of the box "stretch kit" inclusion of longer boom, belt, and pushrod, allowing customers the freedom to select from 320mm main blades, all the way to 360mm!
Common features within the Oxy Heli lineup are certainly passed to the Oxy 4 design. These are: oval boom without supports, tail belt drive, one way tail drive system, incredibly precise head and tail geometry, two piece landing skid system, rigid carbon fiber frame, triple bearing blocks, DFC Rotorhead, and finally an optimized tail efficiency based on Oxy's critical design standards.
Radical design concepts and features that are new and found on the Oxy 4 include a "muscle" profile canopy, offering a modern skinny yet aggressive style, that additionally provides incredible visibility thanks to the highly visible Orange and Blue styling. The canopy is also favorably designed to provide ample room for large batteries like 4s 2200mAh or even 6s 1300mAh for crazy 3D performance. An oversized tail pulley assures precise tail power delivery and additionally provides less drag resistance providing an incredible lifetime of the belt. Two sets of tail blades are included with the kit, that additionally have a surface finish look similar to carbon fiber, that have been found to provide less noise and improved tail thrust efficiency.
