The Apex shatters the glass ceiling in freestyle frame design.

Through a process of continuous refinement and always striving to improve we have created a new breed of freestyle frame. The Apex does not compromise in stiffness or durability, so you never have to choose between confidence and performance.

Unique design elements new to the FPV world make your build and maintenance more simple than ever before. The toughness of the frame itself is increased while also offering much better protection for your investment in-flight electronics.

The DJI HD Apex is a variant of the base frame which perfectly houses and protects the DJI Air Unit. By changing only the top and upper main plates of the Apex it becomes the perfect platform for anyone wanting to experience an HD video feed.

Note: Motors/Electronics are *not* included!

Apex Arm Design

The arms of an FPV frame are the key structural component that translates the thrust from the motors to the majority of the mass in the aircraft, which is secured to the body of the frame. The design of the arms and how they are attached to the body is one of the most vital aspects that influences the performance of an FPV frame.

There are multiple problems that can occur with existing arm designs which can lead to poor performance, difficulty tuning and added cost. The Apex addresses all of these problems with a simple and unique new design that eliminates all arm slop and drastically increases durability.

Perfectly Symmetrical

Symmetrical arms make it possible to pocket one side of the part without introducing the need for distinct left and right arms, making you require more spare parts. We use a pocket instead of a hole under the motor to increase durability and we embed a press nut to simplify attachment and avoid clearance issues under your stack.

Simple Maintenance

Flight electronics are mounted to the upper main plate using countersink bolts. This completely decouples the arm attachment from the electronics mounting. Arms can be replaced using two bolts without any disturbance to your stack.

Shoulder Bolts and Threadlocker

Our custom machined shoulder bolts act as a solid steel pin through the arm which eliminates slop and tolerance issues. The precision shaft passing through the arm removes all side-loading of the carbon laminations on to the chisel-like threads of a regular bolt. Factory added threadlocker and custom aluminum cone washers spread the load of the clamping force and ensure the bolts will not vibrate loose.

Key to the Apex

At the apex of a masonry arch, a keystone locks all the stones into position and allows the arch to bear weight and be self-supporting. A keystone is a hallmark of strength and good design, the Apex FPV frame is no different and the carbon key sits at the heart of the frame to distribute forces applied to the arms.
