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.

OXY Heli Oxy 4 Sport Edition Electric Helicopter Kit
The quality on this helicopter is fantastic and it fly's just as good. Building was simple with a very low parts count. Its a solid built machine that will hold up in a crash. We are flying OXY at our field and they perform great. I will buy another OXY!

OXY Heli Oxy 4 Sport Edition Electric Helicopter Kit
I put together over 15 helicopters in my life and this is the worst one I've ever seen I purchased this from amain Hobbies the design and frame and parts quality is excellent but the tail shaft is too small it's not true 4mm and there's play it going back and forth and in and out it because there's space in between the pin and pulley and the shaft is undersized= cannot be fixed by replacing the tail parts=this helicopter is not worth flying tail assembly will eventually fail
