Finally, a neat and clean DJI O3 toothpick is here. With our DJI O3 canopy, the DJI O3 air unit fits perfectly to the frame, you don’t need to stack the DJI O3 air unit to the frame anymore. The digital camera. air unit and the antenna all have dedicated mounting room.  About the flight performance, with dry weight of 114g and total weight of 165g(including a 4s 450mah battery), the 3.5inch toothpick is a great and quiet sub250g cruiser, you can get over 5mins flight time with a 4s 450mah-550mah battery. And of course, it can freestyle too. Check out MoeFPV freestyle video below.  

  • Recommended Battery: 4S 450mAh battery
  • Recommended Props: HQ 3.5 x 2.5 x 3

Note 
1. The color of DJI O3 canopy will change in different batches.
2. To complete the build, you should also purchase the DJI O3 air unit, props and the battery yourself.
3. Note about the ESC firmware Preflashed to the Poly F405 AIO

Since November 2024, the Poly F405 AIO minimum start up power value is adjusted to 1010 and maximum startup power value is adjusted to 1080. This means that this setting should work well for many builds, in many cases, you don’t need to adjust the startup power value manually.

For your reference, for the first batch Poly F405 AIO preflashed with V0.21 Bluejay ESC firmware, the startup power value is min1010, max1020. If you receive the first batch Poly F405 AIO preflashed with V0.21 Bluejay ESC firmware, we recommend you adjust the start up power value to min1010, max1080 in the ESC configurator.
