Stretch X Frames

Think of Stretch X Frames as the elongated sibling of True X Frames. These frames have stretched arms, which add stability and reduce turbulence. They’re a hot favorite among FPV (First-Person View) racers who need that extra bit of steadiness to cut through the air more effectively.

Plus Frames

Plus Frames look just like a giant "+" sign. They offer an alternative footprint to X Frames but are generally more prone to breaking because the arms are all centered at a single spot. If you’re looking to try something different from the more conventional frames, a Plus Frame could be a fun experiment.

Stretch Plus Frames

Addressing the field of view issues seen in Plus Frames, Stretch Plus Frames extend the front arm to give you a clearer view. This slight modification can make a significant difference in how you experience flying, especially when capturing videos or navigating through tight spaces.

Z Frames

Okay, now picture a zigzag. Z Frames utilize a stepped configuration to reduce turbulent air reaching the motors at the rear during forward flight. This feature makes Z Frames particularly efficient and gives them a unique look.

Common Frame Sizes

180 mm to 250 mm: Mini and Micro Quads

These tiny frames are perfect for indoor flying and light outdoor activities. Mini and Micro Quads are compact and nimble, making them ideal for quick maneuvers and flying through tight spaces.

300 mm to 450 mm: FPV and Sport Racing Quads

In this size range, frames cater to high-speed racing and FPV activities. They offer a balance between stability and agility, providing enough space for mounting additional equipment without compromising on speed.

500 mm to 800 mm: Aerial Photography and Heavy Lift Drones

For those interested in capturing breathtaking aerial footage, larger frames ranging from 500 mm to 800 mm are the way to go. These frames are designed to carry heavy cameras and other equipment, offering stability and endurance.

Choosing the right quadcopter frame can make or break your flying experience. From the balanced True X Frames to the oversized aerial photography frames, understanding the different types and sizes helps you pick the one that suits your flying style. So, whether you're mounting a GoPro or simply racing for the thrill, there's a perfect frame waiting for you to discover.
