3.5 Inch 155mm Carbon Fiber FPV Drone Frame Kit - Compatible With DJI Caddx Polar Vista System

FPV pilots, check out this awesome 3.5 inch carbon fiber frame that's specifically designed for the DJI Caddx Polar Vista system! With a 155mm wheelbase and weighing only about 51g, this frame is built for performance and durability.

The carbon fiber construction is top-notch - 3K material with a 3.0mm bottom plate and 1.5mm side/upper plates that can handle those inevitable crashes. Everything is precisely cut and finished, ready for your build.

Compatibility is where this frame really shines. It's made specifically for the Caddx Vista HD system with perfect fit for that camera unit. The camera installation width is 19mm with adjustable angle from 0° to 60° so you can dial in your perfect FPV view.

For your electronics, it supports 20x20mm and 25.5x25.5mm flight controllers with M2 mounting, and motors with 9x9mm or 12x12mm mounting patterns. Think 1404 3800KV brushless motors for that perfect power-to-weight ratio.

The package includes all the 3D-printed parts you need - camera side plates, motor protectors, antenna mount, and even a universal action camera mount. No need to source extra parts separately!

With the right setup (like a 750mAh 4S battery), you're looking at 11-13 minutes of smooth cruising or 4-6 minutes of aggressive FPV flying. The internal height of about 25mm gives you plenty of space for your components without being bulky.

Whether you're building your first digital FPV drone or adding to your fleet, this frame gives you that perfect balance of lightweight performance and crash resistance. The attention to detail in the design really shows when you're putting it all together.

Seriously, if you want a reliable frame that's optimized for the Caddx Vista system and can take a beating, this 3.5 inch carbon fiber option is definitely worth considering for your next build!
