Comet 250/280 - Sturdy Quadcopter Frame with internal controller deck

thingiverse

Tired of flimsy 3D-printed frames that warp while banking, constantly requiring new spare parts and lacking protection for your valuable electronics? Then try the Comet. The Comet was engineered to withstand an enormous amount of force on the arms while being significantly lighter than other comparable frames. The vibration-damped deck is positioned at the center of the chassis to ensure maximum protection for your cam and flight controller. The 250mm variant can accommodate 5-inch and 6-inch props (even though the 6-inch prop makes it challenging to mount the lipo on top) while the 280mm arms provide ample space for a large 4s Lipo + 6-inch prop. Our two test frames have already survived a respectable amount of abuse, including a free fall onto a wooden floor. Please share your experience with the frame!
